Lightweight. Fast. Grippy. Fast. Responsive. Fast. There are many words to describe the speedy Superior 4.5. The Quantic™ midsole offers a lightweight yet responsive ride for high-speed trail days. TheMaxTrac™ outsole and multi-directional lug pattern brings grippy traction to any terrain. The improved upper brings better breathability and durability. And finally, the removable StoneGuard™ offers lightweight rock protection for when the trails get extra rugged.
- Places your heel and forefoot the same distance from the ground to encourage proper, low-impact form throughout your run.
FOOTSHAPE™ TOE BOX
- Allows your toes to relax and spread out naturally for more comfort and stability.
- The Fit4Her™ technology means we customize every women's shoe to the unique anatomy of the female foot.
- Grid-like grooves in the midsole allow your foot to flex while being lighter, for more speed and better performance.
- Hook-and-loop tab allows strapless gaiter attachment that prevents debris from building up beneath the shoe.
- Canted lugs positioned strategically beneath the metatarsals to provide traction at toe off.
- A perfect combination of grip, traction and durability that will eat up gnarly terrain like a boss.
- Quantic™ was inspired by a desire to combine the plush feel of Altra EGO™ with a lightweight ride, it cushions every step and floats over any surface
