Footwear element including a flexible outer sole assembly and a flexible upper, the footwear element extending lengthwise from a rear end to a front end, widthwise between a lateral portion and a medial portion, and height-wise from an outer surface of the outer sole assembly to an upper end, the footwear element having a shoe insertion opening. The footwear element includes spikes projecting from the area of the outer surface of the outer sole assembly. The footwear element includes at least one reinforcement, the reinforcement including a base and a wall, the base extending opposite the outer sole assembly outside of the footwear element, the wall extending from the base toward the upper end, also outside of the footwear element.

A cleat for footwear. The cleat includes a base layer that attaches to the outsole of the footwear, a cushioning layer and a traction element layer. The traction element layer is attached to the base layer solely by the cushioning layer. Each of the cleat layers provides friction with the ground when the cleat engages the ground. The durometer of the base layer and the durometer of the traction element layer are greater than the durometer of the cushioning layer. When a user steps on a surface wearing a shoe outfitted with these cleats, the resilience of the cushioning layer at once both lessens the impact of the traction elements on the ground surface and lessens the reaction force on the user's foot transmitted through the shoe's outsole. The user's comfort is thereby enhanced.

A golf shoe has an upper, a midsole, and an outsole. The outsole includes a plurality of wave-like flex channels, surrounded by a hard base material. The hard base material provides stiffness for support and stability while the flex channels allow the outsole to bend when a user walks or swings a golf club. The outsole also has a plurality of receptacles for attaching and removing cleats, providing traction between the golf shoe and a ground surface.

A method for manufacturing a shoe sole with multi-material spikes includes: providing a spike-forming mold which includes an upper mold and a lower mold, wherein the lower mold includes a first filling hole which is in communication with the first spike cavity, different materials are placed in the first spike cavity to form the multi-material spike; providing a first mold which includes a second spike cavity; providing a second mold which includes a second filling hole; assembling the first and second molds, together to form a sole cavity, wherein the multi-material spike is placed into the sole cavity, a sole material is filled into the sole cavity through the second filling hole, and then the multi-material spike and the sole material are adhered to each other by hot melting; and opening the first and second molds, and obtaining a shoe sole with the multi-material spike.

A sole structure for an article of footwear includes a plate, a plurality of cleats extending from the plate, and an auxetic structure disposed between the plurality of cleats. The auxetic structure is affixed to the plate such that an outer surface of the auxetic structure is positioned between a lower surface of the plate and a tip surface of at least one of the plurality of cleats.

An athletic shoe comprising an upper portion; a sole; and a cleat assembly comprising a base for coupling to the sole, wherein the cleat assembly includes a post assembly having a biasing member; and a cleat body, wherein the cleat body is disposed on the post assembly; wherein the post assembly has 360 tiltability, relative to the sole; wherein the cleat body also has 360 tiltability, relative to the sole. A cleat assembly for an athletic shoe is also provided.

A method for securing studded shoes by using the effect of inertia, wherein a studded shoe, comprising a structure of stud and receptacle combination, the stud including a ground-engaging part. The stud and the receptacle are adapted to be secured together by a threaded connection comprising a bolt (6, 8) on one of the components of the stud and a threaded socket (5, 7) on the receptacle, both adapted such that said bolt (6, 8) can be driven into said threaded socket (5, 7). A securing means of the components serves to become inter-engaged at least when the bolt (6, 8) is fully driven into the threaded socket (5, 7) to resist unscrewing of the components. The securing means comprises at least one locking accessory that fastens in the counterclockwise direction, in an arrangement such that the direction of torque formed by the direction of the inertia in wearer's shoe sole and the center of the threaded connection, and the relative number and/or position of the threads of the threaded connection determine the position and locking direction of the stud relative to the receptacle.
