System O2 is one of our original cushioning technologies. By encapsulating a thick air bag into the heel of PU foam midsole, System O2 provides a cushiony soft ride and maximum impact protection.
Foam Lite insoles are tuned for maximum comfort and are formulated with a breathable moisture wicking material called Ortholite. This durable lasting foam stays squishy for a long time for superior comfort. The insoles also incorporate recycled rubber to make them more eco friendly.
