Lone Peak 4 Low RSM Trail Running Shoe

Sprinting up steep alpine trails is no easy task. It's even tougher when you consider the heavy precipitation trapped by imposing ranges and formidable peaks. Protect yourself from soaking-wet trails with the Altra Men's Lone Peak 4.0 Neoshell Trail Running Shoe. Equipped with the weatherproof protection and improved ventilation of a Polartec Neoshell membrane, the Lone Peak 4.0 Neoshell keeps your feet blissfully dry from pouring rain, puddle splashes, and mud-caked trails, while stil breathing exceptionally well.

Staying true to Altra's Zero Drop running philosophy, the Lone Peak 4.0 features a Zero Drop platform that places the heel and forefoot at the same distance from the ground. Not only does this design platform naturally align your feet, but more importantly, it promotes smooth landing without the high-impact of an elevated heel. Going one step further for a natural running position, FootShape design naturally spreads out toes, instead of the squeezed stance of traditional running shoes with narrower toe boxes.

Protecting your feet, StoneGuard maximizes protection from stone bruises when you're cruising across craggy ridges and rocky mountain trails. The cushioned EVA midsole lends the shoe a plush feel without sacrificing ground feel or being overly bulky. And because you'll be running up and down inclines, the TrailClaw lugged sole ensures traction for sprinting uphill and braking control on steep downhills.

  • A sturdy trail shoe for tackling mountain traverses
  • eVent upper is breathable and durable
  • EVA midsole keeps your feet comfortable on long runs
  • MacTrac soles hold traction on technical descents
  • Moderate cushioning for rugged trails
  • Item #ATR004Q

Altra Til Death

I've put it through the wringer

These are my second pair of Altra trail running shoes and they are the best! I ran the Altra Superior 2.0’s until there was no tread and the upper separated from the sole, and I loved every mile of it! The Lone Peak 4 RSM’s are the most solid shoes I’ve worn. I was looking at the Superior 4’s because I loved the 2’s so much, but decided to go with the Lone Peaks for a more meaty and durable sole, waterproof upper, and the gaiter loop on top is very useful! I’ve taken them on multiple longer distance runs, between 11-17 miles, with mud, snow, and plenty of rock gardens and they’ve carried me through everything like Hermes through the clouds. I’m excited to keep running em and enter some races this summer! Altra till death!!

I got these shoes for my dad who is always outside, whether its hiking or going to my little brother's soccer games or going down the street for whatever reason. He had an old pair of Altra Escalantes that were really worn out. At this point he could only wear them as slippers inside the house because they were so worn. He loved these Lone Peak 4's. He is in between 10.5 and 11. We went with the 11's and they fit great. He loves the traction of these and the comfortability of the sole. He usually replaces the insole with his own Dr. Scholls but these are perfect for him and he is excited to take these on some spring hikes.

Altra has won me over! The Altra Lone Peak 4.0 RSM is an amazing shoe! I wear this shoe daily for everything I do. The first few days wearing the shoe your foot may ache as it gets used to the 0 drop and spread out attitude of the Altra. I have a pretty flat foot so these work great for me, however they still over great support. They are super light weight and offer an aggressive tread. I am thinking of trying out the high top version for a backcountry hunting shoe. I will keep you posted.
