If you are on the cusp (aka between sizes) and aren't sure which size to choose, keep in mind it's most important that your heel fits well in the heel cup of the insole - it should be "in" the heel cup, not "on" it. How they workSuperfeet insoles help adapt the flat midsole of your footwear to the 3-dimensional shape of 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 for every step.
