The pedal, incorporating a clamp for a shoe sole block (3) with a projecting tip (4), has a retaining member (R) for the block in the form of a transverse bar (28) at the forward end of a cavity (24) into which the block is inserted. A similar bar (33) at the rear of the cavity allows the block to be removed. Each of the transverse bars (28, 33) is situated at the top of two vertical arms (30, 35), the lower ends of which are coiled round rods (25, 26) to form torsion springs (32, 37). Each of the components made up of a transverse bar, arms and coiled ends is made in one piece, especially of steel wire. |
