Update of the popular Altra Lone Peak 4.0. Designed for off-road running, on hard-packed or soft muddy trails. In keeping with most Altra updates, it is evolution rather than revolution, with some strategic features and material upgrades as listed below.

  • Maintains its familiar snug, yet flexible heel collar, and traditional midfoot feel. 
  • The lacing system has improved, giving an even snugger midfoot fit. The tongue now incorporates 3 lace loops, designed to work with the laces to hold it in place and stop the foot moving from side to side. 
  • Usual durable Quick-Dry Air Mesh with a rip-stop finish. 
  • Trademark wide FootShape™ toe box that allows the toes to spread out naturally. 
  • Also includes gaiter straps at the heel and bottom of the tongue. Used with gaiters, will help keep dirt out on dry trails.


  • Changed to a slightly different, more durable foam.
  • Double layer of cushioning materials. EVA directly above the outsole, and top-loaded softer A-Bound compound under the insoles, make for a smooth, cushioned ride. 
  • Altra also include a forefoot “stoneguard” or rock plate to help disperse shock, but also to protect against sharp or gnarly stones and roots on the trail.


  • Unchanged, with the new MaxTrac™ rubber compound, providing excellent grip, traction and durability. 
  • 4 mm deep lugs.
  • Trail Claw grip, featuring a variety of hexagonal and triangular shaped lugs.

  • The zero-drop of all Altra shoes ensures your heel and forefoot are the same height from the ground. This has been shown to encourage more mid and forefoot landing, which reduces impact forces and gives a more balanced run.
  • Although zero-drop, with a 25mm stack height, it also has plenty of cushioning. (The stack height, simply put, is the amount of cushioning under your feet. In this case 25mm of cushioning.)
  • Excellent grip on grass and hard-packed trails.
  • Forefoot, flexible stone guard to lesson impact from stony trails, while at the same time not restricting natural movement of the foot. 
  • Altra’s wide toe box really does allow the toes to splay and spread naturally. This allows for better forefoot stability through toe-off and can help reduce lost toenails and blistering on longer runs. 


  • If you are considering Altras, the zero-drop may take some adjustment. If you have worn 4/5mm drop shoes before it will not feel too different. If most of your recent shoes have been on a higher drop, like 8-10mm, they can take a few miles and outings to get used to. Calves and Achilles area can feel a little tight, but as long as you build up the mileage cautiously and you run slowly initially, all should be well. 
  • Grip is absolutely fine on hard and soft trails, but if deep mud or bog is to be encountered regularly, a deeper lugged shoe is possibly more practical.


Having put a lot of miles on a pair of Lone Peaks in the last 12 months, on Scottish lowland and highland hill and trail paths, first thing I can say is, they are incredibly durable.

I have worn a lot of lower – 4-6mm – drop road and trail shoes over the years, as well as the traditional higher drops of many road shoes. I personally didn’t find the zero drop an issue at all. As mentioned on the cons above, if you haven’t had a low-drop shoe before, a transition period is needed, maybe alternating with your existing shoes for a while to enable you to adjust.

Despite the wide toe box, they are snug around the midfoot and ankle, making for an incredibly good fit. Although it is not a stiff heel collar, the strategic placing of the heel overlays gives you the feeling of an element of control that some softer heel tabs don’t give you.

We all know that there is no perfect trail or fell shoe for every run or race, but the lugs of the Lone Peak seem totally adequate on hard packed and muddy trails. I would probably opt for the deeper fell shoe grip of the Altra King MT or similar for open hill and moorland runs, which have serious mud and more technical sections.
