Designed primarily for tighter fitting footwear, Superfeet BLUE is our most versatile product. BLUE provides excellent biomechanical support for the widest variety of foot shapes. Featuring Agion antimicrobial top cover treatment to reduce bacteria and help prevent foot odor. Superfeet insoles help adapt the flat midsole of your footwear to your foot. The distinct Superfeet shape helps to stabilize the foot, while the deep, structured heel cup and full-length foam provide support and comfort for every step. Ideal for feet with low to medium arches that cannot tolerate maximum support.
