The Altra Lone Peak 9 Waterproof is built for trail runners tackling technical terrain in wet conditions. A 100% PFC-free Hydroguard waterproof membrane, recycled mesh, and no-sew overlays keep water out while maintaining breathability and durability on fast, uneven trails. A reinforced heel and webbing ghillie lacing system provide a secure lockdown for confidence on climbs, descents, and tight switchbacks.
The Altra EGO™ midsole offers responsive cushioning with natural flexibility for smooth foot movement over mixed terrain, while the zero-drop platform and 25 mm stack encourage balanced, low-impact strides. The MaxTrac™ outsole delivers reliable grip across wet rocks, loose dirt, and muddy trails, and the Original FootShape™ Fit allows toes to splay for better control and stability during longer efforts.
Designed for runners who don’t slow down when conditions get rough, the Lone Peak 9 Waterproof delivers lightweight protection, comfort, and performance for wet-weather trail running.
