Superfeet started making custom insoles for ski boots in the mid-70s. The REDhot is a direct result of those years of experience. With these insoles you get a snug, stable fit with less shifting and fewer pressure points or hot spots.
Superfeet insoles help adapt the flat midsole of your footwear to your foot. The distinct Superfeet shape helps to stabilise the foot, while the deep, structured heel cup and full-length foam provide support and comfort.
