ALTRA MEN'S SUPERIOR 4.5 - YELLOW PORT
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.
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.
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.
Our Quantic™ foam offers a luxurious and lightweight cushioned midsole, designed for miles and miles of comfort.
Our grippy MaxTrac™ outsole provides the perfect combination of grip, traction, and durability on all types of terrain.
These canted lugs on the outsole are strategically placed beneath the metatarsals to provide added traction underfoot.
This hook-and-loop tab allows our strapless gaiter to easily attach to the shoe, adding protection against rocks and debris.
These grid-like grooves in the midsole are designed to provide flexibility and movement.
