Abstract: This sport shoe includes an outer sole suitable for ground contact, an inner sole situated under a foot of an athlete, and an intermediate sole between the outer and inner soles. The outer sole is divided, along a longitudinal axis of the shoe, into at least three transverse zones including a front zone located at least partially below the toes of the foot, a median transverse zone provided to be at least partially located below a region of the foot extending between the base of the toes and a front end of the arch of the foot, and a rear zone provided to be located at least partially below a region of the foot extending backward from the front end of the arch of the foot. The three transverse zones are separated by transverse flexion lines whose flexibility is greater than the flexibility of the three transverse zones.

Abstract: A shoe, in particular a sports shoe, which includes a front body for accommodating phalanxes of a foot, a rear body for accommodating a heel of the foot, an internal lateral body and an external lateral body linking the front body and the rear body, and a sole. The shoe has a clamping device for exerting a pressure essentially laterally on the rear body and a clamping member and pinching members for cooperating with the clamping device and wherein the pinching members are positioned laterally on either side of a median strip of the rear body and whereby the pinching members place force against the median strip by tightening of the clamping device.
