Abstract: A footwear element that includes an outer sole assembly and a flexible upper, as well as spikes projecting in the area of an outer surface of the outer sole assembly, the flexible upper including a lower portion adapted to cover the foot of a user, the flexible upper having a shoe insertion opening. The upper includes an upper portion extending the lower portion in a direction away from the outer sole assembly, the upper portion being provided to cover at least the ankle of the user, or the ankle and a portion of the lower leg.

Abstract: An article of footwear including an outer sole assembly and an upper, the outer sole assembly extending lengthwise from a rear end to a front end, widthwise between a lateral side and a medial side, and heightwise between a surface for contact with the ground and a surface for connecting to the upper, the sole assembly including a first reinforcing layer extending lengthwise from a rear end to a front end, widthwise between a lateral side and a medial side, and heightwise between a distal surface and a proximal surface, the first reinforcing layer having transverse slits. The sole assembly includes a wear layer and a first damping layer, the wear layer demarcating the contact surface. The first damping layer is located between the wear layer and the first reinforcing layer.
