The result of years of research and field testing, Superfeet CARBON is ideal for the dedicated athlete who demands high performance results. Superfeet's revolutionary insole achieves a new level of lightweight performance by combining a carbon fiber-reinforced stabilizer cap with a durable, ultralight foam layer. CARBON's distinct biomechanical shape and low-volume design can help improve the fit and feel of tight-fitting athletic footwear like cleats and lightweight shoes. Superfeet insoles keep their shape, delivering reliable support and comfort for up to 12 months or 500 miles, whichever comes first.
