Abstract: Outer sole assembly of a shoe having a rigid blade, having a modulus of elasticity greater than 750 MPa, inserted between an upper cushioning layer and a lower cushioning layer. The external sole assembly includes a rigid support, having a modulus of elasticity greater than 100 MPa, including: a lower bridge extending substantially over the entire width of the upper cushioning layer in the area of at least one transverse segment of a central zone; and a lateral wing covering a portion of the lateral surface of the upper cushioning layer, the cover portion covering at least one strip having a width of at least ten millimeters, the strip extending lengthwise towards the rear, from the lower bridge.

Abstract: A flexible shoe including an outer sole assembly and an upper, the outer sole assembly including a damping sole extending lengthwise from a rear end to a front end, widthwise between a lateral side and a medial side, and heightwise from a lower surface to an upper surface, the lower surface having lower grooves, the upper surface having upper grooves, the lower grooves of the lower surface being opposite the upper grooves of the upper surface. The lower grooves of the lower surface and the upper grooves of the upper surface correspond to the main articulations of the foot. The lower grooves of the lower surface and the upper grooves of the upper surface demarcate platforms of the damping sole.
