Superfeet Size Chart

There is no industry standard for footwear sizes. That's why Superfeet makes full-length insoles in size ranges (typically spanning 1.5 sizes) to handle the variations. You may need to trim your insoles to fit in your footwear.


What to look for in a proper fit:

  • Check if your heel fits inside the heel cup, and not over the edge.
  • If the insole is too narrow, go up a letter-size.
  • If your toes extend beyond the end of the foam forefoot, go up a letter-size.
