Abstract
Abstract A heel is longitudinally traversed by a threaded stem provided with a head which can be activated from the lower zone of the heel and whose free end is screwed into a blind hole made centrally in a projection of the lower face of a flat cover which is adjusted in a recess made in the upper zone of the heel. The flat cover is solidly fastened to a plate arranged on the upper face of the inner sole by fixing elements which pass through the inner sole and its inner shank.
