Certification is the floor, not the ceiling
Meeting a standard means a product passed a defined set of tests under defined conditions. It does not tell you how the product behaves after six months in a foundry. Our internal programme exists to close that gap.
Impact and compression
Toe caps are struck with a calibrated striker at 200 joules and compressed at 15 kN, with clearance measured inside the cap afterwards. We run these on production samples, not on hand-built prototypes — the two behave differently.
Flex fatigue
A flex rig bends the sole unit through tens of thousands of cycles, then we re-run the energy absorption test. This is where the difference between a good midsole and a cheap one becomes obvious, and where day-one lab numbers stop meaning much.
Anyone can pass a test on day one. The interesting question is what the product does on day two hundred.
Slip testing
A tribometer measures coefficient of friction across contaminated ceramic and steel surfaces at the heel-strike and flat-foot angles that cause real slips. We test outsole compounds both new and after abrasion cycling.
Wear trials close the loop
Laboratory data goes only so far. Every range runs a field trial with partner sites, and the feedback routes straight back into the next revision. Some of our most useful design changes came from a complaint about a lace hook.
