Altra
Runs LargeAltra runs true to size with the brand's signature FootShape toe box, giving you the widest forefoot room of any mainstream running brand. The Lone Peak, Torin, and Escalante all wear your normal size, and the zero-drop platform feels different from traditional running shoes if you are new to the brand. If you have wide feet or have struggled with toe box room elsewhere, Altra is purpose-built for you. No half-size adjustment is needed.
Altra runs large. Size down half a size from your usual.
Foot-shaped, zero-drop
