The best selling X ULTRA 3 MID AERO continues to evolve into an even better hiker. With the new Descent Control Technology, you'll have more confidence on technical trails and for charging downhill. And its breathable, mid-height is ready for any warm weather endeavor.
A refined last works with the reinforced top arm of the sensifit, holding your foot comfortably in place, especially moving downhill.
Stability and cushioning
The Advanced Chassis helps stabilize your heel, and it's surrounded by generous cushioning for maximum comfort on the trail.
Two different types of rubber result in better grip. A patterned area on the heel grabs terrain more aggressively, giving you more control especially on descents.
Built for maximum grip on loose, soft, rugged, and uneven surfaces, Mud Contagrip® uses deep, sharp lugs made from a compound that focuses on adhesion.
Advanced Chassis™ is a molded insert embedded in the outsole. Providing strong lateral support and reassuring protection, it also delivers optimal mobility and flexibility.
SensiFit™ cradles the foot from the midsole to the lacing system, providing a secure, snug, and virtually customized fit all around the foot.
Lug design with deep penetration and multi-directional grip, improving traction on soft surfaces like mud or loose dirt.
A high performance EVA foam that provides shock attenuation.
3D open Mesh provides maximum breathability.
PU coated leather
A polyurethane coated leather that protects it and makes it stronger to last longer.
A soft, breathable lining for extreme comfort.
The tongue is connected to the upper on both sides, preventing debris from entering the shoe, and keeping the tongue centered.
A wrap of leather, synthetic or rubber around the base of the foot that protects the lateral and medial sides of the foot.
