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.

FOOTSHAPE™

Our signature FootShape™ comfort gives your feet more space to sit naturally and is designed to address biological differences in men's and women's feet.


BALANCED CUSHIONING™

Our Balanced Cushioning™ platform positions your heel and forefoot at an equal distance from the ground, encouraging better alignment, better form, and a low impact landing.


MAXTRAC™

Our grippy MaxTrac™ outsole provides the perfect combination of grip, traction, and durability on all types of terrain.

TRAILCLAW™

These canted lugs on the outsole are strategically placed beneath the metatarsals to provide added traction underfoot.

GAITERTRAP™

This hook-and-loop tab allows our strapless gaiter to easily attach to the shoe, adding protection against rocks and debris.

INNERFLEX™

These grid-like grooves in the midsole are designed to provide flexibility and movement.

QUANTIC™

Our Quantic™ foam offers a luxurious and lightweight cushioned midsole, designed for miles and miles of comfort.
