The Shoe Bending Tester is designed to evaluate the flexing resistance and durability of finished shoes and sole materials. By applying repeated reciprocating bending at fixed angles and frequencies, the tester measures folding performance and monitors crack initiation or growth, providing objective data for quality control and footwear development.

Applications

(1)Testing bending resistance of finished shoes, including sports, casual, and work footwear.

(2)Assessment of sole material durability, including rubber, EVA, and synthetic soles.

(3)Quality control in footwear manufacturing to ensure consistent product performance.

(4)Research and development of new footwear designs or sole materials.

(5)Evaluation of aging effects on footwear under repeated flexing conditions.

(6)Applicable in laboratories, footwear factories, and quality inspection agencies.
