Abstract: A shoe for preventing ankle injuries comprises a sole with a ground-engaging surface, and lateral and medial edges associated with respective lateral and medial connecting portions interconnecting and extending between the ground-engaging surface and the lateral and medial edges. At least one of the connecting portions defines a surface area of reduced friction provided, e.g., in the form of retrofitted patches, which are circumferentially surrounded by adjacent surface areas having a relatively high coefficient of friction. Friction is differentiated in different areas of those parts of the shoe which are implicated in injury mechanisms, and injuries may thus be prevented in the recovery phase after injury, and primary prophylaxis may be achieved. The area of reduced friction reduces the ability of the wearer's foot to rotate relative to ground when the load of the wearer's body is shifted towards or lands near the edge of the shoe.
