UNISEX SHOE SIZE CHART

All Altra shoes are designed with FootShape comfort to give your toes more room to spread out naturally and address biological differences in men’s and women’s feet.

Sizing

We recommend ordering Altra running shoes ½ size larger than a dress shoe. We want you to have the best fit possible. That’s why we offer a 30-day money-back guarantee. If the fit isn’t just right, you can send it back for a different size. The Lone Peak and Torin models are available in Wide (2E width compared to our traditional D width).
