    Lone Peak 4.0 Trail Running Shoe

    Whether you're getting up at sunrise to get in a quick trail run before work, or to hike until sundown and do it all again tomorrow, the Altra Lone Peak 4.0 Trail Running Shoe is there to help you maximize your performance on the trail. Newly updated with a more durable upper and a grippier sole, the 4.0 builds upon the reliable performance of previous models, which have become favorite of everyday trail runners and thru-hikers alike.

    The redesigned upper is more durable than any of its predecessors, so it can hold up to everyday abrasions on the trail and withstand longer miles, which helps with its growing popularity as a backpacking and thru-hiking shoe. The sole represents the biggest update—its MaxTrac rubber offers better grip and more durability than previous versions, with a more aggressive TrailClaw lug pattern to help you grip the trail in any conditions, wet or dry. You've also got reassurance against sharp rocks and other trail hazards, thanks to the StoneGuard rockplate, which has been updated to more directly map the skeletal structure of your foot, giving you the same protection as before with more natural flexibility.

    Apart from updates, the shoe boasts Altra's classic foot-friendly design. A wide toe box lets your feet splay natural for comfort and increased performance, while the Zero Drop platform allows for a more natural and low impact stride. Specific to the trail you've got a protective rubber toe cap with drainage points for wet days, and integrated gaiter compatibility to help keep out trail debris.

    I'm not a huge runner myself but heard great things about these shoes for hiking. These shoes make me want to run. They are light and fast. They make running fun.

    Altra is starting to finally dial in their fit a little bit! I loved the 3.5, but the sizing and fit in the heel was way off. In this version I found the fit to be much better, with a locked down heel due to the strap on the tongue and a narrower midfoot. Having a trail running shoe that feels more secure has been a huge improvement. This version feels less cushioned, which has allowed for a much more responsive run but I dont think I would run anything over 25 miles in this version. Being more responsive that past generations makes the lone peak 4.0 feel faster and more agile. Although not the same ultrarunning shoe of genrations past, this is definitely a step up in quality and materials. After over 100 miles they are holding up well so far. It took me maybe 60 miles to really appreciate this shoe for what it is, and I’m pretty happy I waited for them to break in. As always, love the zero drop and wide toe box. As far as fit goes, I was an 11 in the 3.5 but am a 10.5 in the 4.0 so I would say this shoe is truer to size than the last generation.

    Fast as Heck.

    As light weight and flexible as it gets, with the durability of a work horse. Structurally it is a step down from the 3.5's but by the time I got these on, my feet were strong enough to go the distance. Great for swift short runs or knock-down, drag-out long hauls!

    Such an Improvement

    I went from the 3.0 to these. Can't say enough about them. much stiffer but flex in all the right places, grip is far better with bigger lugs, breathable and even look better. I'll be getting more.

    Love these

    I'm a PNW runner and I do all my running on 100% trails. The trails around here (North Bend, WA) are mostly rocky and rooty and often wet. I've had the Lone Peak 4.0s for a couple weeks now and I've put about 60 miles on the them, the longest run being 22 miles. I really love these shoes! I'm coming from a pair of Lone Peak 2.0s and I noticed a couple big differences immediately. First the heal fits snugger and the ankle feels more supported then the 2.0s did. I used to have to lace my old shoes in a special way so that my heel didn't slip, not anymore. Second, The 4.0 doesn't feel as cushy in the sole, it feels a little more minimalist. This doesn't bug me, but just don't expect the soft slipper feeling sole of the older altras with these, they're still comfy just not as much as before. Third, Thee shoes really do seem more durable then my old 2.0s. I'm a fan of the material they used on the upper.
    Also I love the burlier tread, I did a long run on a rocky trail right after it rained and the traction on these shoes was awesome! never slipped and always felt sure-footed in these. All in all I love these shoes.


      I wanted to give an idea of the sizing of this shoe. I normally take a men's 11 for gym and everyday wear. For hiking I normally go with 11.5 for more room. In a Nike Wildhorse, it gives me decent toe room, in old Merrill Moab's it is pretty loose all around. So I went with 11.5 in these. That gave me a decent amount of toe room still, maybe a tad less than the Wildhorses and a bunch less than the Moab's, but still enough. The zero drop is noticeable, and they are comfortable. The sole seems gummy and sticky and soft, so I expect good traction, but less durability than a Vibrum hockey puck-like sole. Overall it's just a first impression, but I like them.

      Unanswered Question

      Does the 4.0 have the same or more breathability than the previous?
