Featuring a seamless wrap-around engineered knit upper, the Altra Superior 4.5 Trail Running Shoes ensures an incredibly comfortable and well ventilating construction that keeps you cool and free from distraction. A Quantic™ midsole with InnerFlex™ grooves gives soft and responsive cushioning and allows your foot to bend and flex naturally as you navigate technical offroad terrain. Finally, a combination of durable MaxTrac™ and TrailClaw™ lugs provide advanced grip and traction when you need it most.
With a zero-drop construction, your heel and forefoot are placed at the same distance from the ground ensuring comfortably balanced cushioning that promotes proper, low-impact form with each stride.
Enhancing both comfort and stability, the FOOTSHAPE™ toe box gives enough room to allow your toes to relax and spread out naturally as you move.
Inspired by a desire to combine the plush feel of Altra EGO™ with a lightweight ride, Quantic™ cushions every step so you feel like you float over any surface.
Take on technical terrain with confidence thanks to the perfect balance of superior traction alongside long-lasting durability.
