Leave sore, tired feet behind with Superfeet's Hike Cushion insoles – lightly structured support made to feel like part of your hiking footwear. Patented Adaptive Comfort Technology flexes and adapts to your foot's natural motion while an energizing heel cushion disperses impact and reduces fatigue.
