The Superior 4 takes an already lightweight, fast trail shoe and makes it even lighter. The upper has been completely redesigned in a wrap-around style for added security and support; the midsole features Altra’s proprietary Quantic™ foam, while the outsole is now made of Altra's sticky MaxTrac™ rubber. To top it off, the rounded heel and improved lug pattern is made to fly down the trail with ease and speed.
