The Ross Flex Tester evaluates the zigzag resistance and flex fatigue performance of sole materials. Pre-cut sole test pieces are mounted on the tester and subjected to repeated 90° zigzag bending. The notch growth rate is measured after testing to quantify the flex cracking resistance of the material, providing an objective assessment of sole durability.
