Abstract
A boot that includes a sole made of at least two layered portions, i.e., a wear layer and a reinforcement, or nerve layer. The nerve layer is equipped with a flexible structure located inside a frame, the structure being formed by at least one transverse recess that defines, between its two ends, the contour of at least one strip centered in the nerve layer longitudinal direction. The sole of the invention offers reinforced longitudinal flexibility through the strip, while being capable of being transversely deformed in its central zone by attenuating ground surface roughness.
