Mammut Aenergy Trail Speed vs Salomon S/LAB Pulsar 4

In this full A/B test, I put two more "light and fast" trail shoes of 2026 head-to-head: the all-new Mammut Aenergy Trail Speed vs the Salomon S/LAB Pulsar 4. The Pulsar has been the benchmark lightweight trail racer for years—but version 4 changed the formula. So the big question is: does Mammut’s new Aenergy Trail Speed challenge Salomon’s dominance, and does it bring back some of the magic that earlier Pulsar versions had? In this on-trail comparison, I break down: Ride feel & ground contact Stack height vs Stability tradeoffs Fit, lockdown, and agility at varying grades and speeds Where the Mammut feels more “old-school Pulsar” Can either shoe double as a daily trainer? ➡️ S/LAB Pulsar 4 ➡️ https://salomon.pxf.io/raqMmd ➡️ Rabbit apparel at REI ➡️ https://rei.pxf.io/yqPMDG ➡️ Rabbit Cocoon 2.0 (women's) at REI ➡️ https://rei.pxf.io/55VEJo ➡️ Rabbit Runners pants at REI ➡️ https://rei.pxf.io/qzY5Mn Humble Running x The Feed - 10% off for YOU! ➡️ https://rstr.co/the-feed/humblerunning 👉 NNormal Kjerag 02 vs Nike Terra Kiger 10 // Fast Daily Trainers? 👉 https://www.youtube.com/watch?v=RDRsRmewKzk&list=PL6d8pVmxEoIRAuFZNn0E2jt4eerhUoNhZ 👉 Salomon Ultra Glide 4 First Look // Better Than S/LAB (For Now)? 👉 https://www.youtube.com/watch?v=iYMwphETvbw&list=PL6d8pVmxEoIRAuFZNn0E2jt4eerhUoNhZ 👉 BEST Trail Running Shoes of 2025 // I Actually RACED in ALL of them !!! 👉 https://www.youtube.com/watch?v=DD6pzLKtUHE&list=PL6d8pVmxEoIRAuFZNn0E2jt4eerhUoNhZ 👉 Salomon or Craft?
