As the foot strikes 1.heel, 2.mid-foot and 3.toe-off on Ryn's seven layer sandwich structure, its EVA embedded graphite shank see-saws on the Ryn air tunnel, thus recreating the stable natural foot strike environment humans were evolved to follow. As a direct result of this guided motion, Ryn's X-Run footwear: reduces stress on back, hips, knees and ankles; strengthens and tones the core, glutes, thighs, calves and back muscles; aligns the body; stimulates the arch and enhances blood circulation; stabilizes and guides the foot strike and promotes energy return.
