It includes an upper sole (6) composed of two articulated plates (7, 8) and a lower sole (5) consisting of a plate separated from the upper sole (6) by a space (4) which contains a device (13) for guiding and transmitting, towards the front of the foot, the energy due to the placing of the heel on the ground, and a powerful spring (20) which, associated with a locking member (22) which is suddenly unblocked during raising of the heel, gives the athlete a supplementary impulse at the end of a stride. <IMAGE>
