Abstract
A shoe, in particular a sports shoe, includes an inner sole and an outer sole the heel part of which, hollowed out with an opening oriented upwards, includes an internal shock-absorbing element, which is preferably formed as a single block with the outer sole. This shock-absorbing element has a hollow tubular open configuration, the annular section of which is not of constant thickness over all of its height, locally presenting a zone of reduced thickness, from which preferably the deformation by flexing of the shock-absorbing element occurs. Preferably, it has an outer wall that is perpendicular to the general pressure plane of the outer sole and an inner wall with a concave curvature.
