Natural Movement Meets All-Weather Protection The Altra Lone Peak 9+ GTX continues the legacy of the most trusted name in trail running, now reinforced for the harshest conditions. This version features a Gore-Tex® Invisible Fit upper, which provides full waterproof protection without the bulk or stiffness of traditional waterproof liners. By bonding the membrane directly to the upper, the shoe maintains a lightweight, flexible feel and impressive breathability, ensuring your feet stay dry through creek crossings, mud, and rain.

Built on Altra's Balanced Cushioning™ platform, the Lone Peak 9+ encourages a low-impact landing and a natural stride by keeping the heel and forefoot at the same height from the ground. The signature FootShape™ toe box allows your toes to splay naturally for greater stability on technical climbs and descents. Underneath, the MaxTrac™ outsole utilizes a multi-directional lug pattern to provide aggressive grip on slippery rock and loose dirt, making it the ultimate choice for hikers and runners who don't let the forecast dictate their adventure.

Key Features:

• Gore-Tex® Invisible Fit: Provides premium waterproof and breathable protection with a bonded construction that fits and feels like a non-waterproof shoe.

• Original FootShape™ Fit: Altra’s roomiest toe box design allows the big toe to remain in a straight position for more power and stability.

• Balanced Cushioning™: The zero-drop platform aligns the heel and forefoot to encourage better form and a more natural foot strike.

• MaxTrac™ Outsole: A high-friction rubber compound combined with TrailClaw™ canted lugs for superior traction on varied and wet surfaces.

• Altra EGO™ Midsole: A responsive yet soft foam compound designed to provide increased energy return and durability over long miles.

• GaiterTrap™ Hook-and-Loop: A convenient attachment point allows for easy integration with trail gaiters to keep sand and debris out of your shoes.
