As a transition shoe: Due to the low groundfeel and low flexibility, these shoes are great for transitioning for those used to stiff, supportive shoes, and wanting a gradual change. You’ll still get the benefits of zero drop and a wider toebox, while causing as little disruption to your day to day experience as possible. Sometimes runners will also choose a shoe like this as their first zero drop shoe.

The upper materials are fully waterproof. To care for the shoes just brush off excess dirt with a brush and wipe with damp cloth.

The Lone Peak 9+ GTX is designed to handle wet, unpredictable conditions while keeping you comfortable and confident on the trail. Built for hiking and trail running, it performs best across mixed terrain, from muddy paths and wet rock to long-distance adventures—anywhere you need reliable traction, waterproof protection, and natural foot movement without sacrificing comfort.

It’s not intended for technical mountaineering or extreme alpine terrain. Featuring a waterproof and breathable GORE-TEX Invisible Fit upper, a Vibram® Megagrip outsole, and a responsive Altra EGO™ midsole, it delivers secure footing and a lightly cushioned ground feel. With Altra’s signature roomy toe box and flexible design, it’s versatile enough for daily trail use, but truly shines when tackling legendary trails in all weather conditions.
