Test principle
The insole backpart stiffness tester is used to testing 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.
