Abstract
A shank for providing stability and torsional control to a shoe comprises a generally rectangular body having a pair of legs extending non-symmetrically from a first end for providing flexibility at the ball of the shoe, and a semicircular tab formed from a second end for enhancing the rigidity and torsional stability. A crested ridge formed along the underside of the shank provides stiffness to the shank's body while the legs allow for flexibility in the shank to accommodate the slight angular bending, twisting or sideways rocking that occurs at the ball of the shoe. From a side view, the body of the shank is curved to look like a generally elongated S-shape which follows the inclined form of a shoe lasting board. A stabilizer protruding in relief from the top side of the shank is used to align the shank with the shoe lasting board prior to permanent affixation.
