Go faster on the trail with the Altra Superior 4.5 Trail Running Shoe. The newest version of this lightweight trail shoe has gotten even lighter, and hasn’t sacrificed any performance in doing so. The upper has been completely redesigned in a wrap-around style for a snug and supportive fit, and the new lighter-weight midsole features Altra’s Quantic foam for cushioned comfort and support on your long trail excursions. For trail-specific features you’ve got ultra-grippy MaxTrac rubber on the outsole, along with a redesigned lug pattern for uncompromising traction on all the variable surfaces you’ll be zipping over. There’s also a protective underfoot rock plate that keeps your feet guarded from sharp rocks and roots, and removes easily if you’re trying to lighten the weight on mellower terrain. A hook-and-loop attachment tab lets you easily attach a compatible ankle gaiter to keep trail debris from sneaking in your shoe. You’ve got all that plus Altra’s foot-forward design, featuring a Zero Drop platform for a healthy stride and a Footshape toe box that lets your toes splay out naturally for a healthier foot motion and better ground control on the trail.
