The Lightfeet Active Neutral Insoles combine a shock absorbing heel insert and a NITRO REBOUND forefoot pad for maximum comfort during your run. The AERO SHOCK cushioning in the heel provides shock absorption to disperse impact with each step. NITRO REBOUND in the forefoot adds cushioning and provides a responsive spring with each stride. With a low arch height, these insoles are suited for runners that don't need additional support. As an added benefit the insoles are odour-resistant and feature SwiftFoam to keep you feet cool and dry.
