Sizing notes
Altra’s unique FootShape™ toe boxes and Zero Drop™ platforms create a straighter shape compared to typical running shoes. This design gives your toes room to spread and allows your feet to remain 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.
