Women's Sizing Chart

All Altra shoes are designed withFootShape™ 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. So if the fit isn’t just right, you can send it back for a different size. The Lone Peak 5 and Torin 5 are available in Wide, a D width (compared to our traditional B width).
