Altra Mens Size 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.

We recommend ordering Altra running shoes ½ size larger than a dress shoe. We want you to have the best fit possible. The CM size is the length of the innersole, we recommend around 1.5cm space from your longest to to the end of the shoe to achieve a good fit.
