The invention relates to a shoe (C) including a shoe portion and a sole (S), the sole including two main portions that are pivotably connected together and being characterized in that the second front portion (200), secured to the shoe portion of the forepart, extends to the rear of a first swivel pin (A1) in a lever arm portion (210), projects to the rear within the same plane as that of the front portion (200), and is kinetically secured to the latter. The rear end of said arm has a second swivel pin (A2) with the end (310) of at least one resilient module (300), the other end (320) of which is pivotably connected around a third swivel pin (A3) secured to the rear end of the rear portion (100) of the sole (S). |

1. A shoe comprising a shoe portion and a sole, the sole comprises two main portions that are pivotably connected together:
a first rear portion linked to the rear and median zone of the shoe portion of the shoe, and a second front portion linked to the zone of the forepart of the shoe portion of the shoe, with these two portions of soles being pivotably connected according to a first horizontal cross pin located substantially under the natural joint between the forepart and the rear portion of the foot, characterized in that the second front portion secured to the shoe portion of the forepart extends to the rear of said first swivel pin in a portion forming a lever arm in a proportion substantially equal to ⅔ and ⅓, i.e. ⅔ for the front portion linked to the shoe portion and ⅓ for the rear portion, and being projected to the rear in the same plane as that of the front portion and kinetically secured to the latter, the rear end of this arm has a second swivel pin with the end of an elastic module of which the other end is pivotably connected around a third swivel pin secured to the rear end of the rear portion of the sole, in such a way that when the triangle formed by the three swivel pins is flattened, the three pins become substantially coplanar and the elastic module is compressed and wedged.
