CA 2016672

A sports shoe having a vamp and a lower support part which includes a sole, and a wedge arranged on the sole, a mounting insole and an additional insole which is in contact with the user's foot. The shoe includes, associated with the lower support part, an insert comprising elements which are elastically deformable under pressure and which are enclosed in an airtight casing advantageously of a plastic material, the insert being arranged in a seat provided in the wedge and in the mounting insole in a position corresponding with the heel of the foot. A further insert may be provided at a different location of the shoe. The elastically deformable elements are barrel shaped. This shape allows considerable absorption of the stresses caused by the user's foot as he moves, and at the same time allows a large part of the absorbed energy to be retransmitted rapidly but gradually to the foot.
