Made from premium man-made materials and breathable mesh, the company based the design on their popular Rhythm Walker. A scientifically designed rubber outsole provides the stability that’s essential for a safe workout. A molded EVA insole offers protection from over pronation and plantar fasciitis thanks to utilizing patented Orthaheel technology. For runners looking for a personal solution, the Orthaheel inserts can easily be removed for a pair of custom orthotics.
