Altra Lone Peak 9+

Altra Lone Peak 9+ review: what runners say

Fit

True to size with a wide, foot-shaped toebox; Altra itself notes a tendency to run slightly small, recommending sizing up half a size. The GTX model reduces internal volume due to the Gore-Tex membrane thickness.

Feel

Flat, natural ride on zero drop with 25 mm of stack; the 9+ GTX model with Vibram Megagrip outsole is noticeably stiff, especially initially, requiring a break-in period of at least 15–20 km.

Durability

Over 50 km logged with no significant signs of wear; full-coverage Vibram Megagrip outsole. Rated for distances up to 50 miles, with reservations on longer ultras given the cushioning volume.

Best for

Trail runners looking for an all-terrain shoe on mixed, technical, and muddy routes. The GTX model is geared toward snow and wet trail sessions; those seeking race-specific performance or exclusively technical terrain will find limitations.

Weak points

Pronounced stiffness on the 9+ GTX model, with break-in required even for experienced runners. The Gore-Tex upper noticeably reduces internal volume and breathability. Some runners flag the short laces as a minor construction flaw.
