Device For Transforming On Demand A City Shoe Into A Sports Shoe And Shoes Adapted To Said Device

Abstract

Two plates ( 2, 3) are arranged under a forefoot and a heel and comprisies longitudinal edges ( 2 a, 2 b, 3 a, 3 b ) inclined with respect to the transversal axis of a sole and the lateral edges ( 2 c, 2 d: 3 c, 3 d ) which are not parallel and have different lengths. Winglets bonded to the lateral edges are fixed to the sides ( 7, 8 ) of the sole by pins or claws. Said invention can be used for transforming a city shoe in to a golf shoe.
