Altra Running SUPERIOR 4 WMS
Altra's lightest running shoe won Runner's World Editor's Choice award last summer and now it's back for more. It feels at home on rugged terrain and will keep your feet padded with Altra's Quantic foam and Maxtrac rubber. Get out and get running!
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 our sticky Maxtrac rubber. To top it off, the rounded heel and improved lug pattern is made too fly down the trail with ease and speed.
