Shoe bending Angle tester

The Shoe Bending Angle Tester is designed to evaluate the rigidity and flexibility of footwear outsoles. By applying a controlled load to the forefoot portion of the shoe, the tester measures the bending angle under specified force and speed. This provides an objective indication of outsole bending performance and helps determine if the sample requires further dynamic flexing tests.

Applications

(1)Testing athletic shoes such as running shoes, basketball shoes, and trainers for forefoot flexibility and bending stiffness.

(2)Evaluation of leather shoes and casual footwear to verify outsole rigidity compliance with design specifications.

(3)Testing work and safety shoes, including steel-toe and composite-toe footwear, for outsole bending performance under controlled loads.

(4)Preliminary assessment of shoe prototypes to determine suitability for dynamic flexing or fatigue testing.

(5)Quality control in footwear manufacturing to ensure consistent outsole stiffness and bending characteristics.

(6)Inspection of children’s shoes for bending flexibility and comfort.

(7)Testing orthopedic and therapeutic shoes to evaluate structural support and bending resistance.

(8)Evaluation of outsole materials such as rubber, EVA, thermoplastic, or PU for bending performance before final assembly.

Technical Parameters

Accessories

(1)Shoe clamping fixture for different sizes

(2)Calibration weights and adjustment wrench

(3)Power cable

(4)Instruction manual

(5)Delivery note/documentation

Test Procedures

(1)Place the shoe or outsole sample on the hard base and secure it using the clamping mechanism.

(2)Set the desired force (30 N) and speed (100 ± 10 mm/min) on the control panel.

(3)Initiate the bending test; the forefoot is bent until the applied force reaches the set value.

(4)Record the bending angle displayed on the LED readout.

(5)Compare results with standard requirements or use as a preliminary assessment for further flexing tests.

Maintenance Information

(1)Regularly clean the clamping fixture and hard base to prevent debris accumulation.

(2)Inspect and tighten moving parts and screws to maintain alignment and accuracy.

(3)Verify calibration of the LED digital display periodically.

(4)Lubricate mechanical components according to manufacturer recommendations.

(5)Store the tester in a dry environment to prevent corrosion or damage.
