A cap for capping an upper surface of a shoe a first layer, a second layer, and a third layer. The first layer has an outer surface that has a coefficient of friction that is greater than that of the upper surface of the shoe that that the cap caps. The second layer is an adhesive layer. Third layer is a release layer that can be peeled off the adhesive layer to expose it, thereby enabling said adhesive layer to stick to said shoe.

Ground-engaging components for articles of footwear include: (a) an outer perimeter boundary rim that at least partially defines an outer perimeter of the ground-engaging component, wherein the outer perimeter boundary rim defines an open space at least at a forefoot support area of the ground-engaging component, wherein the outer perimeter boundary rim is shaped such that the outer perimeter of the ground-engaging component tapers or curves inward moving from a forefoot support area to an arch support area, and wherein a narrowest dimension from a lateral side edge to a medial side edge of the outer perimeter boundary rim is located in a heel support area of the ground-engaging component; and (b) a support structure extending into or at least partially across the open space. The ground-engaging component may have a narrower width dimension in a central heel or rear heel support area than in the arch support area.

An article of footwear has a sole including a toe portion and a heel portion, a toe bumper disposed on the toe portion, the toe bumper being configured to contact a ball, and a heel bumper disposed on the heel portion, the heel bumper being configured to contact the ball, wherein at least one of the toe bumper and the heel bumper has an asymmetric shape.

A sports shoe, particularly for soccer use and the like, comprising an upper and a sole which is provided with one or more studs, each stud being associated with the sole by way of at least one elastically deformable element for the movement of at least part of the stud about its own longitudinal axis in such a manner as to follow the movements of change of direction, traction and stopping of the athlete who is wearing the sports shoe, the sports shoe further comprising a stripping prevention element that lies inside the sole and the stud, passing through the elastically deformable element in order to prevent accidental breakages of the elastically deformable element and/or the separation of the stud during the use of the sports shoe.

A track and field shoe can include an upper, a sole structure, and a toe plate. The upper includes a medial side portion, a lateral side portion, and a toe box portion. The sole structure is attached to the upper and includes a spike plate. The spike plate has an anterior portion, a posterior portion, and a plurality of spikes. The spikes are configured for penetrating a track surface. The toe plate is attached to an anterior portion of the toe box portion of the upper. One or more portions of the toe plate are exposed from an exterior surface of the upper. The spikes are spaced apart from the toe plate such that the spikes disengage the track surface when the toe plate contacts the track surface.

The present invention belongs to the technical field of shoe spikes, and more particularly relates to a carborundum wear-resistant shoe spike. The carborundum wear-resistant shoe spike comprises a shoe spike main body and a nickel coating attached to the surface of the shoe spike main body; the surface of the shoe spike main body is also provided with a carborundum layer, and the nickel coating is disposed between the shoe spike main body and the carborundum layer. Compared with the prior art, the present invention lies in that the outer surface of the nickel coating is provided with the carborundum layer, and since the carborundum layer has the characteristics of good toughness, high hardness, good wear resistance and the like, the wear resistance property of the shoe spike can be greatly improved, and the service life of sports shoes using the shoe spike is prolonged.
