Need a great athletic shoe? Look no further. The Ryn Sports has leather mesh upper with Ryn Encapsulated Air Tunnel Max for an ultimate workout ride. Provides the cushioning you want, and the stability you need. Fits true to size. Width adjustable through speed lacing system. This shoe features Ryn Encapsulated Air Tunnel Stabilized for a stable ride. Provides the cushioning you want, and the stability you need. As the foot strikes the heel, mid-foot, and 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 footwear reduces stress on the 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.
