Full review
Longer notes from the same comments we summarized above.
What people reported
Owners consistently describe the Altra Lone Peak 9+ as "crazy comfy" for walking and hiking, with many noting its roomy toe box. This comfort factor makes it a popular choice among thru-hikers, with one user on the PCT reporting "not one blister" over many miles. Some who have adapted to zero-drop shoes find the transition easy. Newer models reportedly incorporate a Vibram rubber outsole, which generally improves grip compared to Altra's previous Max Track material, although specific performance details for the 9+ Vibram are still emerging. One owner specifically mentioned their LP9+ pair was "holding well" after 200 miles.
Problems people mention
A significant point of concern is the shoe's zero-drop design, which can lead to Achilles pain if users do not gradually adapt their bodies to it. Several new users reported discomfort, emphasizing that these are "not something you just jump into without training." Owners also expressed reservations about the underfoot protection for rocky trails. Despite Altra's "Stoneguard" marketing for debris protection, one detailed review indicated there is "definitely no rock plate running through the shoe," leaving some users worried about foot protection. Furthermore, the cushioning feels less substantial compared to other trail shoes with similar stack heights. A broader trend of Altra's declining quality since the company was sold frequently surfaced, with owners of previous Lone Peak and other Altra models citing issues with soles and toe box fabric not lasting long. Poor customer service from Altra was also mentioned by some.
Where owners disagree
There is some disagreement regarding the toe box width. While many appreciate the roomy toe box for comfort, one user with narrow feet described the Lone Peak 9+'s toe box as "clown-ish." Additionally, some general comments suggest that "new versions are much narrower than previous models," which might contradict the perception of an overly wide toe box for the 9+ or indicate variations across specific models or widths. On durability, one LP9+ owner reported good longevity after 200 miles, directly contrasting the widespread concerns about Altra's recent quality decline.
Who it's for
The Altra Lone Peak 9+ is ideal for thru-hikers and trail enthusiasts who prioritize comfort, a roomy toe box, and are either already accustomed to zero-drop footwear or willing to undertake a gradual adaptation period. It suits those who appreciate ground feel and flexibility, but buyers should consider its suitability for extremely rocky or technical terrain where maximum underfoot protection is a top priority. It's also for those who prefer a non-waterproof shoe for better breathability, acknowledging that waterproof versions can feel warmer.
