A spike structure made of different materials includes: a sole protruding portion, an interface member and a cleat member. The interface member is disposed between the sole protruding portion and the cleat member, so that the sole protruding portion does not directly contact the cleat member, but the sole protruding portion and the cleat member are in contact with the interface member, and because the interface member is easily bonded to the cleat member, the interface member and the cleat member can be fixedly combined by bonding. Besides, the interface member and the sole protruding portion are made of hard materials with similar hardness and are not easily deformed when they are in contact with each other. Therefore, the interface member and the sole protruding portion are not easily slipped off.

An outsole for a shoe including first and second sole segments that overlap at least partially. The first sole segment can include at least one stud and be arranged at least in a mid-foot portion of the outsole. The second sole segment can include at least one stud and be arranged at least in a toe portion of the outsole. In some embodiments, the outsole can include a first cushion element arranged between the first sole segment and the second sole segment and overlapping with at least one first stud of the first or second sole segment. In some embodiments, the outsole can include a second cushion element being arranged between the first sole segment and the second sole segment and overlapping with at least one second stud of the first or second sole segment. In some embodiments, the outsole may be an outsole for a football shoe.

The present disclosure relates generally to traction devices for footwear. In some embodiments, cleats are provided that are operable to provide preexisting articles of footwear with enhanced grip, traction and performance. Certain embodiments of the present disclosure comprise a threaded male extension for interfacing with a preexisting shoe sole and at least one projecting gripping element for contacting or extending toward a ground surface.

The present disclosure is related to a cleat for a shoe. The cleat can include a base having opposing first and second surfaces. The cleat further includes a fastener extending from the first surface and adapted to couple the cleat to a sole of the shoe. Additionally, the cleat can include a plurality of spike legs arranged in a distributed arrangement and extending outwardly from the second surface of the base to terminate in a distal end portion spaced from the second surface. The cleat can further include bristles extending between at least some adjacent pairs of the spike legs away from the second surface of the base.

The invention relates to devices and methods for designing and manufacturing customized footwear, and components thereof. An example method includes a method of designing at least a portion of a sole of an article of footwear customized for a user. The method includes the steps of determining at least one input parameter related to a user, analyzing the at least one input parameter to determine at least one performance metric of a foot of the user, and determining at least one customized structural characteristic of at least a portion of a sole of an article of footwear for the user based on the performance metric.
