Sizing Notes
Altra’s unique FootShape™ toe box and zero to low shoes are built to place your foot in a natural position, with a stable and confident foundation to run on. 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.
