Men's Altra Superior 4 Running Shoe
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 to fly down the trail with ease and speed.Features
- FOOTSHAPE™ TOE BOX Allows your toes to relax and spread out naturally for more comfort and stability in uphill climbs and downhill descents.
- ZERO DROP™ PLATFORM Places your heel and forefoot the same distance from the ground to encourage proper, low-impact form throughout your trail run.

- TRAILCLAW™ Canted lugs positioned strategically beneath the metatarsals to provide traction at toe off.
