Sizing Notes

Altra’s unique FootShape™ toe box and Balanced Cushioning™ platform create a natural fit that follows the shape of your foot, instead of squeezing your toes and raising your heel. Your toes have room to spread out and your foot remains in a flat, natural position. When fitting, be sure to allow a full thumb’s width in front of your toes. If your feet are used to cramped toe boxes, Altra shoes may feel a little big at first. Give your toes some time to get used to the newfound wiggle room.

Altra offers a range of FootShape fits:

Original Fit: The fit that started it all, Original is the roomiest of the 3 options from Altra.

Standard Fit: The most common fit from Altra is right in the middle of Original and Slim.

Slim Fit: The slimmest-fitting Altra option still allows room for your toes to spread out naturally.
