For neutral to slight pronators, the Radius 6 really measures up. Dynamic, fluid-filled HydroFlow units in the heel and forefoot enhance cushioning and absorb shock, assisted by our midsole material, Substance 257. An engineered Cush-Pod Configuration sets the foot in an efficient, balanced position from heel strike to toe-off for added stability. In the outsole, HPR Plus (High Performance Rubber) offers traction control and enhanced durability, with Sponge Rubber strategically positioned in the forefoot area to boost cushioning and flexibility.
