What do you get when you improve on the already adventurous Superior? A lightweight, lightning-fast shoe you can trust on any trail. This certified speed-seeker is trail-ready with a MaxTrac™ sticky rubber outsole, the lightweight and responsive Quantic™ midsole, and the improved upper that’s more locked-in and durable. Throw in improved breathability, better drainage, and a removable StoneGuard™, and the Superior 4.5 is ready to blaze trail like never before.
BALANCED CUSHIONING: 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.
INNERFLEX™: Grid-like grooves in the midsole allow your foot to flex while being lighter, for more speed and better performance.
GAITERTRAP™: Hook-and-loop tab allows strapless gaiter attachment that prevents debris from building up beneath the shoe.
TRAILCLAW™: Canted lugs positioned strategically beneath the metatarsals to provide traction at toe off.
MAXTRAC™: A perfect combination of grip, traction and durability that will eat up gnarly terrain like a boss.
QUANTIC™: 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
