Hit the trails at speed in the Women's Superior 4.5 Trail Running Shoes from Altra. Fast and lightweight with a seamless and durable upper construction and a responsive midsole design alongside advanced underfoot traction for enhanced grip.
Featuring a seamless wrap-around engineered knit upper, the Altra Women's 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.
The Altra story begins in 1998 when Altra founders, Golden Harper and Brian Beckstead, met in high school and have been running together ever since. After years of tinkering and testing prototypes, their running innovations hit the market in 2011 and have gone from strength to strength since.
