Abstract
The shoe shall include at least one spring (R), notably a metal spring, set into the sole between an upper plate (2) extending as far as the back of the shoe and a lower plate (3) to cushion the shoe from shocks from the ground. The upper plate (2) shall be rigid and shall be wholly located behind a line (L) underneath the metatarsus (4) of the foot; the sole shall present an area to allow for transversal articulation (5) in the area of this line (L) in such a way that the angle formed between the upper rigid plate (2) and the section of the sole (6) located in front of the area of articulation may vary; the lower edges of the sides of the uppers (9) of the shoe which cover the foot shall be joined to the upper rigid plate (2); the spring(s) (R, 11) shall be situated in the only part of the rigid plate which will be under the heel of the foot, the whole being such that variations in the load applied to the spring (R, 11) shall provoke an oscillating movement of the upper rigid plate (2) around a transversal line of articulation (L), in relation to the lower plate (3).
