     DETAILED DESCRIPTION 
       [0022]    Various exemplary embodiments of the shoe spike system are disclosed herein. As seen generally throughout the figures, the present system  10  generally relates to a novel spike  12  that can be attached to and removed from certain shoes  14 . Also disclosed herein are a variety of methods and apparatus used for attaching and removing the disclosed spikes, including a specialized aglet  16 , as is best shown in  FIGS. 5 ,  8  and  10 - 14 . In certain embodiments, the aglet  16  further comprises a coupling head  18  which is adapted to couple to the spike by way of an opening  20  in the spike. For purposes of this application, “spike” is meant to include any kind of spike or cleat that attaches to the bottom of a shoe, including without limitation a shoe used in athletics, and aglet is meant to include any kind of attachment to the end of a shoelace, drawstring, or the like. 
         [0023]    Turning to the figures in detail,  FIGS. 1-14  depict various embodiments of the shoe spike system. As seen in the exemplary embodiment depicted in  FIG. 4 , certain exemplary embodiments of the system  10  comprise at least one spike  12  set in a shoe  14  and at least one aglet  16  further comprising a coupling head  18  adapted so as to allow a user  1  to loosen and tighten the spikes  12  easily and without carrying any extra equipment. As best depicted in  FIGS. 1-2 , certain exemplary embodiments comprise spikes  12  having an opening or other female mating region  20  formed to accept a corresponding male region mounted on the aglet. Other coupling means are possible, as would be apparent to one of skill in the art. 
         [0024]    Continuing with  FIGS. 1-2 , in certain exemplary embodiments, the system comprises a spike  12  having a first end  12 A and a second end  12 B connected by a solid portion  12 C. In these embodiments, the first end  12 A of the spike  12  can be tapered to a point, so as to aid the spike  12  in facilitating traction between the shoe and the surface the shoe is used on. In such embodiments, the spike  12  can be constructed from any kind of material typically used for a spike, including without limitation metal, plastic, rubber, other synthetic polymers or combinations thereof. 
         [0025]    In these embodiments, the second end  12 B of the spike  12  has a connection that can be coupled to the shoe (as shown fitted in  FIG. 4 ). This connection can be a threaded male connector (as best shown in  FIG. 1 ). On the second end  12 B of the spike that is sized to mate with a female connection on the shoe (as is shown in  FIG. 6 ), however other connections are possible. These other connections include a magnetic connection between the spike and shoe, a peg and slot type connection, a twist and lock connection, or any other equivalent apparatus or method adapted for connecting a spike to a shoe, as would be readily apparent to one of skill in the art. Certain alternative embodiments can also utilize a male threaded connector on the shoe connecting to a female threaded connector on the spike  12 . 
         [0026]    As depicted in  FIGS. 1-2 , in certain exemplary embodiments, the spike also has an opening  20  defined into the solid portion of the spike  12 . This opening  20  is adapted to mate with the coupling head  18  of the aglet  16 . This opening  20  could be defined either partially or completely through the solid portion. One advantage of an opening completely through is that it can be accessed by the aglet from either direction, but this is in no way necessary to the function of the system. In certain exemplary embodiments, the opening  20  may be defined substantially perpendicular to an axis connecting the first and second ends of the spike, though, again, this is not required for the system to function. 
         [0027]    As can be seen in  FIGS. 1-3 , this axis between the first  12 A and second  12 B spike ends is generally a substantially straight line. The cross-section of the spike can be any shape, including without limitation circular, triangular, rectangular, hexagonal, or circular with two flattened sides defined by parallel chords through the circle. 
         [0028]    In certain exemplary embodiments, a spike  12  that has a threaded connector (for example, as depicted in  FIGS. 1 &amp; 6 ) as its connection to the shoe can have certain materials applied to the threads on the second end  12 B to assist the second end in forming a tight mate with the female threaded connection on the shoe. In certain embodiments, these materials can include nylon, Teflon, tape, plastic or other equivalent materials that accomplish the goal of facilitating a tight male-female connection. This material could be applied anywhere threads exist for connecting the spike to a shoe, including internally or externally on either the spike or the shoe. 
         [0029]    In other exemplary embodiments, certain materials can be applied to the threaded connector  12 B on a second end of a spike that assist in enabling the spike to be screwed into the shoe. The materials may then contribute to resistance against being unscrewed. These materials include grease, oil, and other kinds of lubricants that would make it easier to screw the spike into the shoe, and then after the spike is in the shoe would help the spike resist being unscrewed. 
         [0030]    The opening  20  that is otherwise defined in the side of the solid portion of the spike in the embodiment described above allows a person to insert an object into the spike, and then exert pressure on the object in such a way as to create a force in a clockwise or counterclockwise direction around the axis between the first and second ends of the spike  12 . This facilitates attachment or removal of the spike by way of the coupling head  18 . In certain embodiments, the object inserted into the opening  20  in the spike can also be anything with a small enough cross-section to fit into the opening  20 —it need not necessarily be the coupling head  18 . 
         [0031]    As shown in  FIGS. 4-7 , certain exemplary embodiments of the system also comprise an aglet  16 , further comprising a coupling head  18  that is adapted so as to be inserted into the opening  20  in the side of a spike  12 . In certain embodiments, this is a male-female coupling, as described above, though other methods of coupling would be apparent to one of skill in the art. In certain exemplary embodiments, the aglet  16  is coupled to the end or ends of a shoelace  22  opposite the coupling head  18 , so as to allow it to be kept with the user without adding substantially any weight or further equipment to the user. 
         [0032]    As shown in FIGS.  5  and  7 - 14 , in certain exemplary embodiments, the aglet  18  comprises a coupling head  18  that is generally cylindrical. As will be discussed herein, many other shapes are possible. By way of example, the aglet  16  may be adapted so as to have a first end  24  having an opening region adapted for the accommodation of a shoelace  22  or other connection means and a second end  26  adapted for securing the coupling head  18 . While the aglet  16  and coupling head  18  shown in  FIG. 5  appear to be generally rigid forged unit, such as a steel, aluminum, alloy, or hard plastic, in certain embodiments the aglet  16  can be comprised of more malleable material such as shrink wrap plastic, polymer, polyolefin, PVC, biaxially oriented polypropylene, fiber, yarn, titanium or any other suitable material which would facilitate the placement and fastening of the coupling head  18  and shoelace  22  inside opposite ends of the aglet  16 . In certain embodiments, the aglet  16  and coupling head can be formed from the same material, while in alternate embodiments the aglet  16  and coupling head are comprised of different materials. In certain embodiments, the coupling head  18  can be made of metal such as stainless steel, spring steel, titanium, carbon fiber, any number of allows or combinations thereof, plastic, ceramic, rubber, or any other material capable of substantially withstanding a rotational force applied to the aglet  16  in order to rotate the spike  12  by way of the coupling head  18 . 
         [0033]      FIG. 6  generally depicts the manual removal of a spike  12 , as is done in the prior art and as may be done in the current system following the initial loosening of the spike  12 .  FIG. 7  depicts the insertion of the coupling head  18  into the opening  20  of the spike  12 , so as to ease rotation (shown as A) and increase leverage around the axis of the spike  12 . 
         [0034]    As shown generally in  FIGS. 8-14 , in certain exemplary embodiments, the coupling head  18  can be specifically adapted to fit into the opening  20 . This can be achieved by a variety of structures and methods. In certain embodiments, the diameter of the aglet  16  and coupling head  18  may differ, though this is by no means necessary. Further, a variety of other shapes may be employed, such as a cubic, hexagonal, or other polygonal shape, as would be best adapted for the particular opening  20  in the spike. 
         [0035]    In certain exemplary embodiments, and as depicted in  FIGS. 8-14 , the coupling head  18  can take a non-linear form to assist in removing the spikes  12  from a shoe  14 . For example, the coupling head  18  may comprise a steel extruded rod, having at least one angle in it, and be capable of removing a spike with an opening  20  in its side, as described above. 
         [0036]    As depicted in  FIGS. 8-9 , in certain embodiments, the aglet comprises an L-shaped for removing a spike having an opening. In these embodiments, coupling head  18  can be specifically adapted to avoid difficulties in accessing the opening  20 , as would be apparent to one of skill in the art. As shown in  FIGS. 8-9 , and for simplicity, the coupling head  18  having at least a first angle  30  can be inserted into the opening  20  so as to prevent the aglet and shoelace from being substantially in line with the opening and also allow the user to loosen or tighten the spike  12 , as shown by B. 
         [0037]    As shown in  FIG. 10-14 , in certain exemplary embodiments the coupling head  18  can comprise more than one angle  30 ,  32  so as to facilitate the removal of the spike and avoid any problems with tangling or catching that may occur with certain combinations of shoes, shoelaces, and coupling heads having angles of approximately 90 degrees.  FIG. 10  also depicts an aglet  16  comprising shrink-wrap plastic and a shoelace  22 . 
         [0038]    As shown for a variety of views in  FIGS. 11-14 , in certain exemplary embodiments the coupling head  18  can comprise a plurality of angles  30 ,  32  and a plurality of segments  40 ,  42 ,  44 , which can be set in a variety of X- Y- and Z-planes or axis from one another. By way of example, and as shown in  FIGS. 11-14 , the plurality of coupling head  18  segments  40 ,  42 ,  44  are set in differing axis from one another, such that a first angle  30  of less than 90 degrees is set between the first  40  and second  42  segments, and a second angle  32  of less than 90 degrees is set between the second  42  and third  44  segments, such that the plurality of angles  30 ,  32  are set in distinct axis from one another and the plurality of segments  40 ,  42 ,  44  are set in distinct planes from one another. As would be apparent to one of skill in the art, additional angles and segments are possible, and the present system encompasses angles of any size and orientation. This embodiment is in no way limiting to a specific number of angles or segments, nor is it limiting as to the axis, orientations, planes, or other configurations. 
         [0039]    Certain shoes do not have laces or algets, and are instead retained on a user&#39;s foot with the help of a zipper, snaps, or other mechanisms. In these cases, the system can be adapted for attachment to the zipper or snap by similar means as those disclosed above, such that, for example, the aglet can be fitted to couple to the zipper or snap. 
         [0040]    In other exemplary embodiments, a tool for removing a traditional spike could be attached to the aglet  16  in addition to the coupling head  18 , or to another part of the shoe. This tool may be configured to fit around any traditional type of spike, including circular spikes, hexagonal spikes, or substantially circular spikes with two flattened sides. These tools are well-known in the art. 
         [0041]    Another embodiment is a kit comprising other embodiments described above, comprising one or more of: spikes with openings in the side, aglets configured to be inserted into the openings in the spikes, aglets connected to tools used to attach or remove spikes, or objects used to insert into the openings in spikes and attach or remove them. 
         [0042]    In addition to other materials mentioned herein, any or all elements of the system and/or device or apparatuses described herein can be made from, for example, a single or multiple stainless steel, spring steel, titanium, carbon fiber, hard plastic, aluminum, metal, alloy, PVC, polymer, stainless steel alloy, nickel titanium alloy, nickel cobalt alloy, molybdenum alloy, tungsten-rhenium alloy, a polymer, polyethylene teraphathalate (PET), polyester, poly ester amide (PEA), polypropylene, aromatic polyester, a liquid crystal polymer, ultra high molecular weight polyethylene, polytetrafluoroethylene (PTFE), expanded PTFE (ePTFE), polyether ketone (PEK), polyether ether ketone (PEEK), poly ether ketone ketone (PEKK), poly aryl ether ketone ketone), nylon, polyether-block co-polyamide polymer, aliphatic polyether polyurethane, polyvinyl chloride (PVC), polyurethane, thermoplastic, fluorinated ethylene propylene (FEP), absorbable or resorbable polymers such as polyglycolic acid (PGA), poly-L-glycolic acid (PLGA), polylactic acid (PLA), poly-L-lactic acid (PLLA), polycaprolactone (PCL), polyethyl acrylate (PEA), polydioxanone (PDS), and pseudo-polyamino tyrosine-based acids, silicone, zinc, zinc oxide, nickel-titanium alloy, tantalum and gold. 
         [0043]    While multiple embodiments are disclosed, still other embodiments of the present invention will become apparent to those skilled in the art from the following detailed description, which shows and describes illustrative embodiments of the invention. As will be realized, the invention is capable of modifications in various obvious aspects, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not restrictive. 
         [0044]    Although the system has been described with reference to preferred embodiments, persons skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
