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.
Â
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.
