Altra Men's Sizing Information

Men's Sizing Chart

We want you to have the best fit possible. Please follow our tips below to find the right size for you:

  • Firstly, we recommend measuring the length of your foot in centimeters.
  • From that length, we recommend adding 0.5 centimeters to have the right amount of extra space for the tip.

We generally suggest ordering Altra running shoes ½ size larger than a lifestyle shoe. Some styles (such as Lone Peak and Torin) are available in Wide. Our Wide versions are wider in the midfoot, heel, and forefoot than our standard models.
