Altra men's and women's size chart (2024)

Good news from Altra shoes:

  • They run true-to-size in comparison to other running shoe brands
  • These models have the widest toebox in the running shoe industry

When trying your first pair of Altras, prepare to experience significantly more space in the toes than what you’re accustomed to. It may seem like the shoe runs big, so it’s important to take into account your foot length.

If there is about a thumbnail’s width space between the longest toe and the upper, the size is just right.

To raise the chances of getting an accurate Altra size, we recommend measuring your foot length and checking it with the chart below.

Tip: If you fall in between sizes, go with the bigger one.
