SL-L13 Insole Backpart Stiffness Tester

Insole Backpart Stiffness Tester

Application

The insole backpart stiffness tester is used to test the stiffness in the longitudinal direction of steel shanks used for the reinforcement of the waist region of shoes. The shank is clamped at its heel end and bent as a cantilever beam by masses added to its forward end.
The amount of bending is measured and used to calculate the flexural rigidity of the shank.

Why test Insole Back Part Stiffness is important?

Apply force through the heel clip to twist the heel and back around the heel-toe axis. The torque required to achieve torsion is used to calculate the torsional stiffness value. Torsional stiffness contributes to foot support and stability - low stiffness contributes to normal foot function and mobility, while high stiffness tends to inhibit foot function but provides greater support and stability.
