Performance & Feel
Traction hero Critics and testers highlight the Vibram outsole as a transformative improvement for wet, slippery, and technical trail performance.
Balance of cushion and ground feel While not plush, the Altra EGO midsole provides enough softness without dulling trail feedback. Spacious toebox and zero drop provide natural interaction with the terrain.
Stability trade-offs The low-cut, flexible upper offers minimal inherent ankle support. Users experienced less stability on technical terrain, especially when new to zero-drop shoes.
Durability & protection Stoneguard and tough upper construction offer generosity in foot protection for rugged use.
Who Its For
Great for trail runners, hikers, and ultra-distance adventurers who want zero-drop stability, a wide toe-box, solid trail feel, and exceptional traction. Best suited to technical, mixed terrain rather than fast racing or rock scrambling.

It enhances the reliable balance of comfort, zero-drop anatomy, and hardy protection of its predecessors with a high-grip Vibram Megagrip outsole and rugged ripstop upper. Ideal for those craving a grounded yet confident trail shoejust be ready to adapt to the wider toebox and lack of structured support if youre switching from traditional, cushier runners.
