Uppers and outsole flex zones undergo 100,000 continuous flex cycles at room temperature and -10Β°C to guarantee zero cracking or delamination.
Lining mesh and footbed surfaces are tested up to 25,600 dry/wet friction cycles to ensure comfortable wear without pilling or hole wear.
Hydraulic tensile testing verifies upper-to-midsole and outsole bond strength exceeds 3.5 N/mm, far above international athletic footwear standards.
White EVA midsoles and rubber trims undergo 48-hour accelerated UV solar chamber testing to ensure white shoes maintain pristine color on store shelves.
100% of finished shoes pass through high-sensitivity calibrated needle detectors before carton packing to ensure absolute consumer safety.
