An athletic shoe assembly for inhibiting knee and ankle injuries during athletic activities includes a shoe that may be worn during athletic activities. A front cleat unit and a back cleat unit are each positioned on the sole for engaging ground during the athletic activities to enhance traction. Each of the front and back cleat units are rotatably coupled to the sole and the shoe is rotatable about a vertical axis extending through the sole and each of the front and back cleat units. Thus, the front cleat unit and back cleat units inhibit knee and ankle injuries during the athletic activities resulting from a stationary foot and a twisting leg.

The anti-slip sport shoe sole (1) surface has an anti-slip surface (2) with small pieces of hard material (3) that are bonded during the manufacture of the sport shoe with the flexible surface of the sport shoe sole (1). The small pieces of hard material (3) come into contact with the ground upon contact of the sport shoe sole (1) with the ground. The anti-slip sport shoe sole is intended for sports disciplines on soft stadium surfaces.

Provided is a shoe member constituting a part of a shoe, including an injection molded article that includes an inner member and an outer member partially or fully enclosing the inner member, wherein the inner member and the outer member are each formed from a resin composition containing a thermoplastic resin, a shoe including the shoe member, and a method for producing the shoe member.

Functional shoes include a sole, a coupling member including a coupling body detachably coupled to the sole; an auxiliary lever coupled to the coupling body so as to be rotatable toward a bottom surface of the sole; and a fixing part protruding from the auxiliary lever toward the bottom surface of the sole and is detachably coupled to the sole, and at least one functional member provided integrally with the coupling body or detachably coupled to the coupling body to provide a predetermined function to the shoes. The fixing part moves between a coupling position in which the fixing part is coupled to the sole and a separation position in which the fixing part is separated from the sole, by a rotation of the auxiliary lever.

A comfortable overshoe that can be worn over various types of footwear has a flexible, resilient sole and means for releasably attaching the overshoe to a boot or other footwear. The sole has a flexible, generally planar, medial wall, with a plurality of hollow domes formed in and extending from the top side of the medial wall. A plurality of triradial support members extend from the bottom of the medial wall and are spaced around the underside of each dome.
