DETAILED DESCRIPTION
The subject matter of the present invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this disclosure. Rather, the inventors have contemplated that the claimed or disclosed subject matter might also be embodied in other ways, to include different steps or combinations of steps similar to the ones described in this document, in conjunction with other present or future technologies. Moreover, although the terms “step” and/or “block” might be used herein to connote different elements of methods employed, the terms should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly stated.
At a high level, aspects herein are generally directed to a sock for athletic wear having a toe seam located primarily on a lateral side of the sock. An advantage of the toe seam being primarily located on the lateral side of the sock is that comfort for a wearer is improved by presenting an unseamed surface to the medial side of a wearer's foot, particularly to the area of the first hallux (i.e., big toe) of the wearer's foot. In one aspect, the sock comprises a tubular body having a textile wall. The sock may additionally comprise features such as a collar that forms a perimeter edge around a foot opening for receiving a wearer's foot when the sock is worn, a heel opening through which a portion of a wearer's heel extends when the sock is worn, as well as one or more toe openings through which a wearer's toes extend when the sock is worn. In accordance with aspects herein, when a bisecting reference plane bisects the tubular body of the sock into a medial side and a lateral side on opposing sides of the tubular body, the medial side is different from the lateral side at the toe end of the sock since, as described above, the toe seam is primarily located on the lateral side of the toe end.
In aspects, when the sock is an open toe sock, the tubular body may comprise a foot locating feature that is located on the medial side of the tubular body when bisected by the bisecting reference plane. In one example aspect, the foot locating feature may be generally configured to engage an anatomical region of a medial portion of a foot of a wearer when the sock is worn by the wearer. For instance, the foot locating feature may be in the form of a toe anchor that engages an area between the wearer's first hallux and the wearer's second hallux. In this aspect, the toe seam would be located on an opposite side of the bisecting reference plane from the toe anchor. Other foot locating features are contemplated herein such as textures, graphics, knit structures, and the like, where these foot locating features may be located on the medial side of the tubular body when bisected by the bisecting reference plane.
With reference to the bisecting reference plane, the toe seam comprises a first terminal end and a second terminal end. The total length of the toe seam (e.g., the toe-seam length) is the distance between the first terminal end and the second terminal end along the toe seam. In other words, the length of the toe seam extends from the first terminal end to the second terminal end of the toe seam. In one aspect, the bisecting reference plane may extend through at least the first terminal end of the toe seam. In another aspect, the bisecting reference plane may extend through both the first terminal end and the second terminal end of the toe seam, where the toe seam extends from a dorsal portion of the sock to a plantar portion of the sock.
In aspects, the sock comprising the tubular body may be described as having a medial dorsal portion, a medial plantar portion, a lateral dorsal portion, and a lateral plantar portion. When the bisecting reference plane bisects the tubular body of the sock, the medial dorsal portion and the medial plantar portion are located on a first side of the bisecting reference plane and the lateral dorsal portion and the lateral plantar portion are located on a second side of the bisecting reference plane, where the first side of the bisecting reference plane is opposite to the second side of the bisecting reference plane.
Continuing, for an open toe sock having a foot locating feature in the form of a toe anchor, the foot locating feature may extend from the medial dorsal portion of the toe opening to the medial plantar portion of the toe opening of the sock. Thus, the foot locating feature or toe anchor may divide the toe opening into at least two toe openings, with a first toe opening having a first circumference and first diameter and a second toe opening having a second circumference and a second diameter. And, in example aspects, the first circumference and first diameter of the first toe opening may be less than the second circumference and second diameter of the second toe opening. The first toe opening may be configured to receive a first hallux of the wearer when the sock is worn, and the second toe opening may be configured to receive the remaining toes of the wearer when the sock is worn. In other words, the foot locating feature or toe anchor engages the first web space of a wearer's foot that is between the first hallux and the second hallux of the wearer's foot, when the sock is worn. Thus, the open toe version of a pair of socks in accordance with aspects herein will have a right footed sock and a left footed sock to properly engage each foot of a wearer when the pair of socks is worn. It is contemplated that the open toe sock described herein may be suitable for activities such as yoga, bane classes, Pilates, and the like which require the wearer's feet and toes to be able to frictionally engage a floor or exercise surface. In other words, the exposed toes of a wearer may grip the exercise surface.
In other aspects, the sock in accordance with aspects herein may comprise an open heel, or an opening in a heel portion of the sock, to expose the heel of the wearer so that the heel of the foot of the wearer can frictionally engage an exercise surface. In further aspects, the sock may comprise both an open toe and an open heel to provide more contact surface area of the foot of the wearer with the exercise surface, which may lead to greater control in physical activities that require balancing such as those mentioned above.
It is contemplated that the tubular body of the sock having the toe seam located on the lateral side of the sock, in accordance with aspects herein, is knit on a circular knitting machine. In example aspects, at least the toe portion of the sock may comprise a series of reciprocally knit sections that are knit on the circular knitting machine using one or more sets of needles, while remaining needles on the circular knit machine are inactive. The series of reciprocally knit sections are integrally knit with each other, and it least one edge of one of the reciprocally knit sections comprises a free edge (i.e., an edge that is not integrally knit with another reciprocally knit section or with another portion of the sock). The free edge may be seamed to, for instance, the tubular body of the sock to form the toe seam, where the toe seam is generally located on the lateral side of the sock. It is contemplated herein that a technical face of the tubular body is external facing and the technical back of the tubular body is internal facing. That is, the technical back of the tubular body of the sock is configured to face inwardly and is configured to be adjacent to a wearer's foot when the sock is worn.
Positional terms as used herein such as “medial,” “lateral,” “front,” “back” “interior surface,” “exterior surface,” “external facing,” “internal facing,” “inferior,” “upper,” “lower,” “superior,” “top,” “plantar,” “dorsal,” and the like, are with a sock being worn as intended and as shown and described herein by a wearer standing in anatomical position. Thus, the medial side of the sock is positioned adjacent to a medial side of a wearer's foot, a lateral side of the sock is positioned adjacent to a lateral side of the wearer's foot, a plantar side of the sock is positioned adjacent to a sole of the wearer's foot, and the dorsal side of the sock is positioned adjacent to the dorsum of the wearer's foot. An internal facing surface of the sock is configured to be positioned toward a skin surface of a wearer, and an external facing surface of the sock is configured to face away from the skin surface of the wearer.
The term “knit course” as described herein is a predominantly horizontal row of knitted loops (in an upright fabric as knit) produced by adjacent needles during the same knitting cycle. The knit course may comprise one or more stitch types such as a loop stitch, a held stitch, a float stitch, a tuck stitch, a transfer stitch, and the like as these terms are known in the art of knitting. The term “integrally knit” as used herein may mean a textile or fabric having a yarn from one or more knit courses of one area being interlooped with one or more knit courses of another area. The term “technical back” as used herein refers to the inner side or underside of the fabric or textile as it is being knit. The term “technical back” may also be defined as the side of the fabric or textile that contains back loops or purl loops. And the term “technical face” as used herein refers to the outer or upper side of the fabric or textile as it is being knit. The term “technical face” may also be defined as the side of the fabric or textile that contains face loops or weft knit loops. The term “elastomeric” as used herein when describing yarns generally means a yarn type that may provide a maximum stretch greater than about 200% under load prior to returning to its non-stretched state when the load is removed, and some elastomeric yarns provide a maximum stretch of about 400%. Examples of elastomeric yarn types include, LYCRA®, elastane, spandex, rubber, and the like. The term “about” used when, for instance, describing numerical ranges means within ±10% of a designated value unless indicated otherwise.
As used herein, the term “seam” may be defined as an area where two or more edges of a textile are joined together using affixing technologies such as stitching, adhesive, bonding, and the like. In aspects, the seam may be formed in a post-knitting step or may occur simultaneously during the knitting step. Further, the term “foot locating feature” may be defined as a feature (e.g., toe anchor, graphic, texture, pattern, knit structure, and the like) present on the sock that will aid a wearer in differentiating a right footed sock from a left footed sock. This is so that the wearer can don the proper sock on the respective foot in order to experience the full benefits and comfort characteristics provided by the pair of socks in accordance with aspects herein.
Continuing, the term “toe anchor” may be defined as a structure in an open toe sock configured to separate a wearer's first hallux from the remaining toes of the wearer's foot. In some aspects, the toe anchor may be formed in a post-knitting step and secured to the sock using affixing technologies such as stitching, bonding, or adhesives. In another aspect, at least one end of the toe anchor may be integrally knit with the tubular body and the other end of the toe anchor may be secured to the tubular body using the affixing technologies described herein. In yet other aspects, the toe anchor may be integrally knit with the tubular body such that both first and second ends of the toe anchor are integrally knit with the tubular body. For instance, a toe-anchor may be integrally knit with the tubular body if a yarn from one or more knit courses of the toe-anchor is interlooped with one or more knit courses in the tubular body of the open toe sock. Moreover, the term “bisecting reference plane” may be defined as a plane positioned such that it extends through the middle of each sock, dividing the sock into generally equal lateral and medial halves, in accordance with aspects herein. In other words, the bisecting reference plane divides a sock into a generally equal (e.g., in terms of surface area) medial half and a lateral half. The medial half may also be referred to as a “medial side” and the “lateral half” may also be referred to as the “lateral side,” in accordance with aspects herein. Unless indicated otherwise, all measurements provided herein are with respect to the sock in a resting state (i.e., a non-stretched) state at standard ambient temperature and pressure (298.15 K and 100 kPa).
Additional objects, advantages, and novel features of the invention will be set forth in part with reference to the figures, as follows, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned by practice of the invention.
Turning now to FIG. 1, a wearer 10 is shown donning an open toe sock 100 comprising a toe seam 124 primarily located on a lateral side of the open toe sock 100. The open toe sock 100 further comprises a tubular body 128, a collar 110 and an optional integrally knit tab 112 positioned interior to the collar 110 in accordance with aspects herein. The open toe sock 100 is shown in the form of a liner sock or a ped sock although other sock lengths are contemplated herein such as a no-show sock, a quarter sock, a crew sock, or an over-the-calf or executive sock. To don the open toe sock 100, once the wearer 10 inserts her foot into a foot opening defined by the collar 110 (better shown in FIG. 2 and labelled by reference numeral 126), the wearer 10 exerts an upward tension on the collar 110 or the optional integrally knit tab 112, which when present, may act as a lever to pull the collar 110 around the wearer's left foot 18 or right foot 20, respectively.
With further respect to FIG. 1, additional optional features of the open toe sock 100 are depicted including a heel opening 114 through which at least a portion of the wearer's heel 12 extends, and one or more toe openings including a first toe opening 116 through which a first hallux 14 of the wearer 10 extends and a second toe opening 118 through which the wearer's remaining toes 16 extend. As briefly described above, the open toe sock 100 may be suitable for activities such as yoga, barre classes, Pilates, and the like which require the wearer's feet and toes to be able to grab a floor or exercise surface. Because of the number of openings, it may be difficult to orient the open toe sock 100 such that the wearer 10 inserts her foot in the correct opening. To facilitate orientation, as shown in FIG. 2, the open toe sock 100 may comprise one or more foot locating features that differentiate a right footed sock from a left footed sock, such as a toe anchor 120 that extends from a top/dorsal portion 132 of the open toe sock 100 to a plantar portion of the open toe sock 100 and divides the toe end opening of the open toe sock 100 into the first toe opening 116 and the second toe opening 118. As explained further below, the toe anchor 120 may be positioned on a medial side of the open toe sock 100 such that the circumference and/or diameter of the first toe opening 116 is less than the circumference and/or diameter of the second toe opening 118. The difference in the circumferences and/or diameters of the first and second toe openings 116 and 118 may act as a visual indicator of whether the open toe sock 100 is a right footed sock or a left footed sock. If present, the optional integrally knit tab 112 may also act as a visual indicator of the correct foot opening 126 through which the wearer's foot is to be inserted. As well, visual indicia (not shown) and/or different textures (not shown) may be integrally knit into the tubular body 128 and/or printed on to the tubular body 128 to indicate whether the open toe sock 100 is a right footed sock or a left footed sock. For example, the visual indicia may include alphanumeric characters, graphic designs, and the like, that may be included on the top/dorsal portion 132 or the plantar portion of the tubular body 128 of the open toe sock 100.
FIG. 3 illustrates a lateral side perspective view of the open toe sock 100 donned on the wearer's left foot 18, in accordance with aspects herein. And FIG. 4 illustrates a medial side perspective view of the open toe sock 100 in accordance with aspects herein. As shown, the toe seam 124 is primarily located on the lateral side of the open toe sock 100. The toe seam configuration in accordance with aspects herein, improves comfort of a wearer by avoiding pressure points potentially caused by a seam to the medial toe/foot portion of, for example, the wearer's left foot 18 (as shown) and the wearer's right foot 20 (not shown). The pressure points are undesirable since in some instances, they may cause painful chaffing. This may be especially true when the open toe sock 100 is worn for activities such as, for example, bane classes where contact of the medial side of the wearer's foot with a surface may frequently occur.
FIG. 5A illustrates a front view of the open toe sock 100 in an as-worn configuration, and FIG. 5B illustrates a plantar view of the open toe sock 100 in the as-worn configuration. For illustrative purposes, the open toe sock 100 may be bisected by a bisecting reference plane 122, bisecting the open toe sock 100 into a medial side half 130 and a lateral side half 140 having generally equal surface areas. The medial side half 130 is comprised of a medial dorsal portion 131 and a medial plantar portion 133. Similarly, the lateral side half 140 is comprised of a lateral dorsal portion 141 and a lateral plantar portion 143.
Continuing with reference to FIGS. 5A and 5B, the toe anchor 120 is located on the medial side half 130, and extends from the medial dorsal portion 131 of the medial side half 130 of the open toe sock 100 to the medial plantar portion 133 of the medial side half 130, as shown in FIG. 5B. The toe anchor 120, because of its location, may serve as a foot locating feature to signal, for example the wearer 10, whether the open toe sock 100 should be worn on the left foot 18 or on the right foot 20. Further, as discussed above with reference to FIG. 2, the toe anchor 120 also helps define a circumference of the first toe opening 116 and the second toe opening 118, where the second toe opening 118 is larger than the first toe opening 116. In other words, the smaller circumference of the first toe opening 116 would serve to signal the location where the wearer 10 should insert her first hallux. Further, when worn as intended, the toe seam 124 of the open toe sock 100 will be primarily located on the lateral side half 140, as defined by the bisecting reference plane 122.
The toe seam 124, as shown, may extend from a first terminal end 142 on the top/dorsal portion 132 of the tubular body 128 to a second terminal end 144 on the bottom/plantar portion 134 of the tubular body 128. Further, in accordance with aspects herein, the bisecting reference plane 122 may extend through the first terminal end 142 as shown in FIG. 5A. And as shown in FIG. 5B, the bisecting reference plane 122 may further extend through the second terminal end 144 of the toe seam 124. In example aspects, the first terminal end 142 of the toe seam 124 may terminate at or near (e.g., within ±about 1 cm) the bisecting reference plane 122, and the second terminal end 144 of the toe seam 124 may terminate at or near (e.g., within ±about 1 cm) the bisecting reference plane 122. As used herein, the term “about” means within ±10% of a designated value. In example aspects, it is contemplated herein that FIGS. 5A and 5B represent the farthest medial position of the first terminal end 142 and the second terminal end 144 of the toe seam 124 to locate the toe seam 124 primarily on the lateral side half 140 of the open toe sock 100. It is contemplated, however, that the toe seam 124 may have the first terminal end 142 and the second terminal end 144 located differently from the locations illustrated in FIGS. 5A and 5B respectively. For example, the first terminal end 142 and the second terminal end 144 may be located anywhere between the farthest locations shown in FIG. 5A and FIG. 5B, respectively such that the first terminal end 142 and/or the second terminal end 144 are located lateral to the bisecting reference plane 122.
As discussed above, and as further shown in FIGS. 6A and 6B, the toe seam 124 comprises a toe-seam length 125 extending between the first terminal end 142 and the second terminal end 144. In some instances, the bisecting reference plane 122 (shown in FIGS. 5A-5B) may intersect or extend through the first terminal end 142, the second terminal end 144, or both the first terminal end 142 and the second terminal end 144. In a different aspect herein, more than 50% of the toe-seam length 125 may be located in the top/dorsal portion 132 of the lateral side half 140 (also known as the lateral dorsal portion), the bottom/plantar portion 134 of the lateral side half 140 (also known as the lateral plantar portion), or any combination thereof; more than 55% of the toe-seam length 125 may be located in the lateral dorsal portion, the lateral plantar portion, or any combination thereof; more than 60% of the toe-seam length 125 may be located in the lateral dorsal portion, the lateral plantar portion, or any combination thereof; more than 65% of the toe-seam length 125 may be located in lateral dorsal portion, the lateral plantar portion, or any combination thereof; more than 70% of the toe-seam length 125 may be located in the lateral dorsal portion, the lateral plantar portion, or any combination thereof; more than 75% of the toe-seam length 125 may be located in the lateral dorsal portion, the lateral plantar portion, or any combination thereof; more than 80% of the toe-seam length 125 may be located in the lateral dorsal portion, the lateral plantar portion, or any combination thereof; more than 85% of the toe-seam length 125 may be located in the lateral dorsal portion, the lateral plantar portion, or any combination thereof; more than 90% of the toe-seam length 125 may be located in the lateral dorsal portion, the lateral plantar portion, or any combination thereof; or 100% of the toe-seam length 125 may be located in the lateral dorsal portion, the lateral plantar portion, or any combination thereof.
In an alternative aspect and as shown in FIG. 7, the toe seam 124, may extend from the first terminal end 142 on the top/dorsal portion 132 of the tubular body 128 to a second terminal end 144 located generally, for example, at a lateral aspect of the tubular body 128 at a point where the top/dorsal portion 132 transitions to the bottom/plantar portion 134. In this aspect, the toe seam 124 does not extend fully on to the bottom/plantar portion 134 of the open toe sock 100.
Further, although the discussion above has focused on an open toe sock 100, it is contemplated that other types of socks such as a closed toe sock 200 shown in FIGS. 8 and 9 may comprise a toe seam 224 primarily located on the lateral side of a tubular body 228, as shown with respect to bisecting reference plane 222. As well, a closed heel sock 300 shown in FIGS. 10 and 11 may comprise a toe seam 324 primarily located on the lateral side of a tubular body 328, as shown with respect to bisecting reference plane 322. Further yet, a closed heel and closed toe sock 400 shown in FIGS. 12 and 13 may comprise a toe seam 424 primarily located on the lateral side of a tubular body 428, as shown with respect to bisecting reference plane 422.
In aspects, the placement of the toe seam 124 may be achieved by reciprocally knitting a series of sections at the toe end of the open toe sock 100. The edge of the last knit section to be reciprocally knit may be seamed to the tubular body 128 to form the toe seam 124. FIGS. 14A and 14B illustrate the different reciprocally knit sections. FIG. 14A illustrates the top/dorsal portion 132 view of the open toe sock 100, and FIG. 14B illustrates the bottom/plantar portion 134 view of the open toe sock 100. With respect to FIG. 14A, the open toe sock 100 has a toe area 1400, which includes a dorsal segment 1402. The dorsal segment 1402 comprises a first dorsal triangular panel 1406A, a dorsal portion 1406B of a toe anchor segment 1420, and a second dorsal triangular panel 1406C. As shown in FIG. 14B, the toe area 1400 of the open toe sock 100 further comprises a plantar segment 1404. The plantar segment 1404 comprises a first plantar triangular panel 1416A, a plantar portion 1416B of the toe anchor segment 1420, and a second plantar triangular panel 1416C.
With continued reference to FIGS. 14A and 14B, the toe area 1400 of the open toe sock 100 further comprises a medial segment 1440 and a lateral segment 1450. The medial segment 1440 is formed from a medial triangular panel 1444 having a medial base 1442, where the medial base 1442 may extend from a point of intersection 1408 with the bisecting reference plane 122 on the top/dorsal portion 132 to a point of intersection 1418 with the bisecting reference plane 122 on the bottom/plantar portion 134. In a similar manner, the lateral segment 1450 is formed from a lateral triangular panel 1454 having a lateral base 1452, where the lateral base 1452 may extend from the point of intersection 1408 with the bisecting reference plane 122 on the top/dorsal portion 132 to the point of intersection 1418 with the bisecting reference plane 122 on the bottom/plantar portion 134. As will be further discussed, the lateral base 1452 may represent the edge of the last reciprocally knit section that is seamed to the tubular body 128 to form the toe seam 1424. It is contemplated herein that the medial segment 1440, at least a portion of the lateral segment 1450, the dorsal segment 1402, and the plantar segment 1404 are integrally knit with each other and with the tubular body 128.
In some aspects, the tubular body 128 of the open toe sock 100 may comprise circumferentially extending knit courses 1460. In some example aspects, a longitudinal knitting direction of knit courses 1462 that form the lateral segment 1450 and a longitudinal knitting direction of knit courses 1464 that form the medial segment 1440 of the toe area 1400 are in a generally parallel alignment with a longitudinal knitting direction of the knit courses 1460, but are reciprocally knit such that at least a portion of the knit courses 1462 that form the lateral segment 1450 and knit courses 1464 that form the medial segment 1440 of the toe area 1400, do not extend circumferentially around the open toe sock 100. In the same aspect, the dorsal segment 1402 of the toe area 1400 may comprise a plurality of reciprocally knit courses 1466 having a longitudinal knitting direction extending generally perpendicular to the longitudinal knitting direction of circumferentially extending knit courses 1460. And in the same aspect, the plantar segment 1404 may comprise a plurality of reciprocally knit courses 1468 having a longitudinal knitting direction extending generally perpendicular to the plurality of circumferentially extending knit courses 1460. To describe this in a different way, the knit courses 1466 that form the dorsal segment 1402 and the knit courses 1468 that form the plantar segment 1404 of the toe area 1400 may be oriented to be generally perpendicular to the knit courses 1460 used to form the tubular body 128. This may be due to, for instance, how the open toe sock 100 is turned in the circular knit machine during the knitting of the reciprocally knit sections. In some aspects, toe anchor knit courses 1430 used to form the toe anchor 120 may also extend generally perpendicular to the plurality of circumferentially extending knit courses 1460, may extend generally perpendicular to the knit courses 1464 that form the medial segment 1440, and may extend generally perpendicular to the knit courses 1462 that form the lateral segment 1450. The toe anchor knit courses 1430 may extend generally parallel to the knit courses 1466 that form the dorsal segment 1402 and the knit courses 1468 that form the plantar segment 1404.
In some aspects of the open toe sock 100, the tubular body 128 and the plurality of toe anchor knit courses 1430 may comprise elastomeric yarns. Using elastomeric yarns may provide enhanced comfort to the wearer and allow the open toe sock 100 to be donned and doffed more easily. Alternatively or additionally, it is contemplated that the toe anchor knit courses 1430 of the toe anchor segment 1420 may have larger knitted loops than other courses in the open toe sock 100. This feature would further allow a greater degree of mechanical stretch compared to areas of the open toe sock 100 that are knit with smaller knitted loops.
Moving on to FIG. 15, a flow chart of a method 1500 for manufacturing the open toe sock 100 in accordance with aspects herein, is shown. For example, as shown at step 1510, the method may include knitting a tubular body of a sock using a circular knitting machine using all the needles of the circular knitting machine, and as shown at step 1520, knitting continuously from the tubular body of the sock, a toe portion of the sock, wherein the toe portion of the sock is reciprocally knit in a number of different sections using a select number of needles of the circular knitting machine.
In accordance with aspects herein, the toe portion of the sock may be formed according to the method 1600 shown in FIG. 16. FIG. 16 describes a series of reciprocally knit sections, where the sections are knit in a certain order to produce the lateral toe seam described herein. Unless specified, the different reciprocally knit sections are integrally knit with each other. At step 1610, a medial segment, such as the medial segment 1440, is reciprocally knitted where a first side of the medial segment is integrally knit with the tubular body of the sock, as shown at step 1610. The knitting process may continue with reciprocally knitting a first dorsal triangular panel, such as the first dorsal triangular panel 1406A, having a first side integrally knit with a second side of the medial segment, as shown at step 1620, followed by reciprocally knitting a first plantar triangular panel, such as first plantar triangular panel 1416A, having a first side integrally knit with a third side of the medial segment, as shown at step 1630. The process may continue by reciprocally knitting a toe anchor segment, such as the dorsal portion 1406B of the toe anchor segment 1420 and the plantar portion 1416B of the toe anchor segment 1420, of the toe portion of the sock, as shown at step 1640, where a first side of the toe anchor segment is integrally knit with a second side of the first dorsal triangular panel and with a second side of the first plantar triangular panel. Then, the process may continue by reciprocally knitting a second dorsal triangular panel, such as the second dorsal triangular panel 1406C, having a first side integrally knit with a second side of the toe anchor segment, as shown at step 1650, followed by reciprocally knitting a second plantar triangular panel, such as the second plantar triangular panel 1416C, also having a first side integrally knit with the second side of the toe anchor segment, as shown at step 1660. Further, the process may continue by reciprocally knitting a lateral segment, such as the lateral segment 1450, of the toe portion of the sock, as shown at step 1670, where a first side of the lateral segment is integrally knit with a second side of the second dorsal triangular panel, and a second side of the lateral segment is integrally knit with a second side of the second plantar triangular panel. The lateral segment represents the final reciprocated section, and, as such, it comprises a free edge. Thus, step 1680 comprises seaming a third side (i.e., the free edge) of the lateral segment to the tubular body of the sock. The seaming may comprise a post-knitting step and include processes such as stitching, bonding, embroidering, and the like, that would be useful for providing a toe seam in the toe portion of the sock that is primarily located on a lateral side of the sock, in accordance with aspects herein.
