A lug for a sole or outsole of a footwear, i.e. a shoe or a boot, which is able to improve the traction or grip features of the sole itself; sole or outsole equipped with a plurality of lugs and a method for obtaining a mold cast printed with a 3D printing machine to obtain the sole and/or the lugs.

A method for manufacturing a sole structure involving supplying at least one textile sole element having an outer face, including one or more at least partially hot-meltable filament(s); placing the at least one textile sole element in a mould structure including a sole cavity intended to come into contact with the outer face of the textile sole element; placing an inflatable bladder in the mould structure and inflating the inflatable bladder to press the outer face of the textile sole element either directly or indirectly firmly against the sole cavity and heating the textile sole element to melt the at least partially hot-meltable filament(s) and mould the sole cavity onto the outer face of the sole element; obtaining a sole structure including a thermally compressed textile sole element.

A sole portion for an item of footwear having a plurality of cleat systems, cleats, or plate structures that dissipate force by deflecting, deforming, displacing or otherwise shifting under selected force, or by facilitating cleat movement around a radial line during ground engagement.

A cleat assembly for a shoe comprising an anchor for anchoring to the shoe, a cleat, a first biasing member circumscribing the anchor and engaged with the cleat, and a second biasing member biasing the first biasing member. The second biasing member can directly engage the first biasing member or a bushing that circumscribes the anchor. So constructed, the cleat assembly provides multiple degrees of freedom. That is, the cleat assembly provides effective axial shock absorbance coupled with 360 tilting of the cleat for enhancing a user's ability to suddenly change direction when wearing a shoe equipped with the cleat assembly, thereby minimizing stress and impact on muscles, joints and ligaments and enhancing the performance of athletes wearing such shoes.

The present disclosure is directed toward a device that can be worn over footwear to provide traction, such as on slick or slippery surfaces, in snow, or on ice.

A sole structure of a sport shoe with shoe studs includes: inner cleat elements separated from each other and made of a first elastic material; an outsole layer including outsole holes through which the inner cleat elements pass, and hole surfaces of the outsole holes connecting with top portions of the inner cleat elements; and outer cleat elements, formed on and surrounding or being surrounded by the inner cleat elements, separated from each other and from the outsole layer, made of a second elastic material. Each of the inner cleat elements and the outer cleat element formed thereon together form the shoe stud. In the shoe stud, the inner cleat element is visible from a gap between the outer cleat element and the outsole layer. Elasticity of the first elastic material is higher than elasticity of the second elastic material.
