It is used to test the longitudinal stiffness of the steel shank reinforced at the waist of the shoe. Meet the full range of testing needs of the heel, so as to ensure the quality of the shoes.

The principle of operation is simple, force is applied through the heel clip to twist the heel and rotate it back around the heel-toe axis. The torque required to achieve torsion is used to calculate the torsional stiffness value, and the support force and stability of the shoe are judged by the degree of stiffness.
