Altra Lone Peak 9+ GTX

Altra Lone Peak 9+ GTX review: what runners say

Fit

Wide fit, consistent with Lone Peak tradition: roomy toebox, Altra's original last. The Gore-Tex adds thickness to the upper, reducing internal volume, with a sensation of material bunching during the first few outings.

Feel

Low-profile Ego midsole, zero drop, natural and flat ride. Both the Vibram Megagrip outsole and the Gore-Tex introduce a noticeable stiffness that requires a break-in period before it settles.

Durability

Full-coverage Vibram Megagrip outsole; no precise mileage data in available sources, but the Megagrip choice explicitly targets greater durability compared to previous versions.

Best for

Wet technical trail, snow, and winter singletrack. Suited to runners seeking weather protection on technical terrain; less appropriate for those wanting responsiveness or immediate feel from mile one.

Weak points

Pronounced out-of-the-box stiffness, with break-in flagged across multiple sources. The Gore-Tex reduces internal volume and retains heat; high weight (12.4 oz men's) is a recurring criticism.
