Mammut Ducan III High LTH GTX Hiking Boot - Men's Gabbro/Black, US 12.0/UK

What Our Gearhead(R) Experts Are Saying: "I've put the Ducan III High LTH GTX through long day hikes and loaded multi-day trips, and the comfort really stands out.

The Flextron PRO plate adds stability without making the boot feel stiff, and the EVA cushioning keeps my feet feeling fresh late in the day.

Traction is solid on wet rock and loose trail, and the GORE-TEX lining has kept my feet dry through rain and creek crossings." We reach for the Ducan III High LTH GTX Hiking Boot when the plan includes long miles, variable terrain, and days that don't end at the trailhead.

Mammut designed this boot to balance comfort and control, making it easy to move efficiently whether we're grinding up steep switchbacks or cruising rolling ridgelines with a pack on our backs.

The sustainably tanned Mastrotto suede leather upper adapts comfortably to the foot while a TPU-reinforced rand adds protection from rocks and trail debris.

Underfoot, high-rebound EVA cushioning and a Flextron PRO propulsion plate work together to reduce fatigue and keep our stride stable on uneven ground.

A Vibram XS Trek outsole with Traction Lug delivers confident grip in dry or wet conditions, while the waterproof GORE-TEX membrane seals out rain and puddles without sacrificing breathability.
