Whole Shoe Flexing Tester（4 Stations）
The QINSUN Whole Shoe Flexing Tester is designed to evaluate the bending and flexing resistance of complete shoes and soles. By simulating repeated flexing under cyclic tensile stress, the tester identifies potential material fatigue, delamination, cracking, or fracture in the upper, outsole, or foxing. It is widely used in footwear R&D, quality control, and compliance testing, ensuring durability and performance of sports, casual, and work shoes. The instrument conforms to major national and industry standards, offering precise, automated, and safe testing.
Application
Used for assessing the flexing durability and crack formation of footwear, including sports shoes, casual shoes, work shoes, and various types of shoe soles. The instrument’s multi-station design allows simultaneous testing of multiple shoes, improving lab efficiency while maintaining high accuracy.
