## Background
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to socks. More specifically, the present invention relates to athletic socks that provide cushioning and support.
2. Background Art
Many athletes require support for their feet and special socks when moving around to stay comfortable in their shoes. Quick movement from side to side requires additional padding in certain areas as opposed to others to prevent the shoe from rubbing on the foot and causing blisters. Many athletes resort to wearing two pairs of socks in order to achieve the comfort and protection that they require.
U.S. Pat. No. 5,226,194 to Staley discloses a double-layered sock 10 including an inner sock 11 having water vapor transfer properties and an outer sock 12 that is water absorbent to keep perspiration away from the skin. Outer sock 12 has a small vent panel 16 located near its toe end on the top of the sock. The inner sock 11 is preferably concealed by the outer sock 12. Inner and outer socks 11, 12 are secured together by any suitable means, such as sewing, Velcro or snap fasteners, or the like.
WO 03/013290 to Lambertz discloses a sock for sporting activities including an outer sock (A) and an inner sock (B), which are connected to each other by sewing. The sock can include an X-cross bandage (41) (i.e. a band) that supports the ankle. The sock reduces friction between the foot and sock.
Prior art socks that are designed to be used as part of a two sock system are attached at some part of the sock and are not separate. They cannot function without being attached because they would slip with respect to the foot of the user.
Therefore, there remains a need for an athletic sock that uses two socks that are not attached that can provide comfort and remain in place during use.
SUMMARY OF THE INVENTION
The present invention provides for a two sock system, including an inner sock, and an outer sock surrounding the inner sock, wherein the inner sock and the outer sock include a support band system that prevents movement of the inner sock relative to the outer sock.
The present invention further provides for a method of preventing movement between an inner sock and outer sock in a two sock system, by preventing movement of the inner sock on a user's foot, and preventing movement of the outer sock on the inner sock, wherein the inner sock and outer sock are unattached.

DETAILED DESCRIPTION OF THE INVENTION
The present invention generally provides for a two sock system, indicated at 10 in FIGS. 1A-1C, including an inner sock 12, and an outer sock 14 surrounding the inner sock 12, wherein the inner sock 12 and the outer sock 14 include a support band system 16 that prevents movement of the inner sock 12 relative to the outer sock 14. The two sock system 10 provides comfort and support to the foot, especially during rigorous athletic use. The inner sock 12 is generally looser fitting than the outer sock 14 in order to provide a custom fit of the two sock system 10.
The inner sock 12, shown in FIGS. 2A-2D, provides comfort and breathability to the foot in the two sock system 10. The inner sock 12 includes an ankle support band 18 and an arch support band 20 on either side of (i.e. surrounding) a loose portion 22. The ankle support band 18 and the arch support band 20 fit tightly on the foot in order to secure the inner sock 12 to the foot, whereas the loose portion 22 provides comfort and does not contain as much elastic as the ankle support band 18 and the arch support band 20.
Preferably, the ankle support band 18 is located above or at an ankle portion 30 of the inner sock 12. Preferably, the arch support band 20 is located at an arch portion 32 of the inner sock 12. The ankle support band 18 and the arch support band 20 can be different sizes or the same size, or have different tightness depending on the size of portions of the foot. The loose portion 22 can include a heel portion 42 and an instep area 38. It should be understood that the ankle support band 18 and the arch support band 20 can be different sizes and can be located at various lengths of the inner sock 12, as long as they are separated by the loose portion 22, secure the inner sock 12 to the foot, and are at appropriate lengths to function in the support band system 16, described in detail below. On the opposite side of the ankle support band 18 from the loose portion 22 is an upper portion 62 that is not as loose as the loose portion 22 but not as tight as the ankle support band 18. The upper portion 62 can include an upper band 60 for design purposes of any size.
Various additional padded areas can be included at any desired place and in any desired size on the inner sock 12, such as, but not limited to a heel pad 24, a toe pad 26, an instep pad 28, and combinations thereof. Each of these padded areas can be located at any place where it is desired to provide additional cushioning or protection of the foot from rubbing with shoes, and can be tailored to movement in a particular sport. For example, the heel pad 24 can extend on the heel portion 42 from the ankle support band 18 to the arch support band 20. The toe pad 26 can be located on a top side 34 of a toe portion 36. The toe pad 26 can be especially beneficial to tennis players as they tend to wear out this area of sock first. The instep pad 28 can be located at an instep portion 38, and can provide comfort and reduce irritation of the instep while moving. In general, the two sock system 10 provides more cushioning to the sole of the foot than other socks.
Mesh vents 40 can be incorporated in any of the portions of the inner sock 12 as desired for ventilation purposes, with several shown in FIGS. 2A and 2B. It should be understood that the mesh vents 40 can be incorporated in only part of a portion or in the whole portion of the various areas of the inner sock 12. In a particular example, mesh vents 40 can be incorporated in the ankle support band 18, the loose portion 22, the arch support band 20, parts of the toe portion 36, and the instep pad 28.
Preferably, the inner sock 12 is slightly longer above the ankle portion 30 than the outer sock 14 such that the upper portion 62 is seen above an upper portion 66 of the outer sock 14, i.e. the outer sock 14 is shorter than the inner sock 12. However, the inner sock 12 can be any other desired length depending on the style or look desired, such as the same length as the outer sock 14 or shorter than the outer sock 14.
The outer sock 14, shown in FIGS. 3A-3D, provides support in the two sock system 10. The outer sock 14 includes an outer support band 44 that preferably extends over an ankle portion 46, an instep portion 48, and an arch portion 50 of the outer sock 14. The outer support band 44 preferably does not include a heel portion 47; however, the heel portion 47 is preferably tighter than the heel portion 42 of the inner sock 12 to still provide support. The outer support band 44 can cover any suitable part of portions 46, 48, 50. However, the outer support band 44 is preferably sized to correspond to the entire loose portion 22 of the inner sock 12. The outer support band 44 is tight and includes more elastic than the rest of the outer sock 14 (i.e. adjacent toe portion 56, ankle portion 46, and upper portion 64) in order to provide support to the foot. On the opposite side of the outer support band 44 from the toe portion 56 is an upper portion 64 that is not as tight as the outer support band 44. The upper portion 64 can include an upper band 66 for design purposes of any size.
The outer sock 14 can include various padding, such as instep pad 52 located at instep portion 48, for any area of the foot where further comfort is desired. However, it is also desired that the outer sock 14 not be especially bulky so that it is tight fitting and therefore padding can be omitted.
Mesh vents 54 can be incorporated in any of the portions of the outer sock 14 as desired for ventilation purposes. It should be understood that the mesh vents 54 can be incorporated in only part of a portion or in the whole portion of the various areas of the outer sock 14. In a particular example, mesh vents 54 are incorporated in parts of a toe portion 56.
Various portions of the inner sock 12 and outer sock 14 can include design features 58 for style purposes. For example, outer sock 14 can include a diamond design feature 58 in the ankle portion 46. The design features 58 can provide additional support (and include more elastic than other areas) or merely be ornamental.
The support band system 16 prevents movement of the inner sock 12 relative to the outer sock 14 without the need for the inner sock 12 and outer sock 14 to be attached, unlike in previous sock systems. In other words, inner sock 12 and outer sock 14 are not physically attached in any manner, they are unattached. The ankle support band 18 and the arch support band 20 grip the inner sock 12 to the user's foot to prevent movement of the inner sock. The outer support band 44 of the outer sock 14 grips the loose portion 22 of the inner sock 12 and prevents the outer sock 14 from moving with respect to the inner sock 12. Prior art sock designs are traditionally looser in the areas of the support band system 16 compared to the two sock system 10.
The two sock system 10 can be made of any suitable material, such as, but not limited to cotton, nylon, wool, acrylic, fleece, moisture-managing fabrics (e.g. COOLMAX® (Invista Apparel)), spandex, skin-temperature regulating fabrics (e.g. JOCKEY® Staycool), linen, silk, and combinations thereof. Different portions of the two sock system 10, the inner sock 12, and/or the outer sock 14 can be made with different fabrics as desired. It is desired that the materials used for the inner sock 12 and the outer sock 14 not be too thick (except in areas where thicker portions are desired (i.e. the pads) so they can be worn comfortably together in a shoe in the two sock system 10.
The two sock system 10 can be made in any colors and designs desired. For example, the inner sock 12 can be a first color, and the outer sock 14 can be a second color. Team logos and colors can be incorporated in the design as desired.
The two sock system 10 is especially useful while playing sports or moving on one's feet in a rigorous manner. For example, the two sock system 10 is useful for playing tennis, football, baseball, basketball, rugby, soccer, running, hockey, or any other sport.
When the inner sock 12 and outer sock 14 are worn together, the two sock system 10 delays sweat running down the wearer's leg into their shoe and reduces friction between the foot and the shoe. The two sock system 10 further provides support, comfort, and breathability to the wearer.
The present invention further provides a method of preventing movement between an inner sock 12 and outer sock 14 in a two sock system 10, by preventing movement of the inner sock 12 on a user's foot, and preventing movement of the outer sock 14 on the inner sock 12, wherein the inner sock 12 and outer sock 14 are unattached to each other physically. Movement of the inner sock 12 is prevented by gripping the inner sock 12 to the user's foot, and movement of the outer sock 14 is prevented by gripping the outer sock 14 to the inner sock 12. More specifically, ankle support band 18 and arch support band 20 grip the inner sock 12 to the user's foot to prevent movement of the inner sock 12. The outer support band 44 of the outer sock 14 grips the loose portion 22 of the inner sock 12 and prevents the outer sock 14 from moving with respect to the inner sock 12. Each of these elements have been described above.
