"Superfeet® Run Cushion Medium Arch: The Superfeet® Run Cushion Medium Arch is a unisex insole built for runners seeking medium arch support and reliable cushioning during daily training and road running. The Aerolyte™ dual comfort layer sits between your foot and shoe, helping your foot settle into a relaxed position while providing consistent cushioning across each stride. The responsive forefoot zone blends cushioning with rebound so energy transfer through toe-off stays efficient rather than sluggish, and the energizing heel cushion disperses impact and reduces vibration so your foot arrives at each landing with less accumulated fatigue.Adaptive Comfort Technology™ uses a patented design that flexes with your foot's natural movement, supporting smooth heel-to-toe turnover on long runs and tempo efforts alike. MoistureWick™ technology improves wicking and breathability, keeping the foot environment drier during extended wear. Together, these features make the Run Cushion Medium Arch a practical upgrade for runners who want their existing footwear to perform more consistently over time without a rigid, corrective feel.Why Our Fit Experts Love It""I slipped the Run Cushion Medium Arch into my training shoes before a mid-week run and noticed right away how the heel cushion took the edge off impact on harder pavement.
