Designed to handle any kind of terrain, the Altra Superior 5 is a fast, nimble, and lightweight trail running shoe. Sporting the brand's signature 0mm drop and a wider, foot-shaped toe box, the Superior 5 gives runners a natural ride while flying down dirt-covered switchbacks or cruising along open fire roads. The Superior has Altra's "Standard" foot shape which is right in the middle of the "Original" and "Slim" options.
