How it rides

The foam

Altra tuned this midsole soft (4/5 on our cushioning scale). Energy return is above average: the midsole rebounds well without feeling unstable. 30 mm of heel stack keeps you low and connected, with more ground feel than most current trainers. Combined, the ride reads as lively at 3/5 responsiveness.

The plate

A rock plate sits between the foam and the outsole to spread the load of sharp stones and roots. It is protection, not propulsion — it does not add pop, but it keeps the underfoot bruising out of long days on technical ground.

The geometry

A 0 mm drop is close to level. That loads the calf and Achilles more than most runners are used to, so ease into it. The rocker is moderate — enough curve to smooth the roll-through without dictating your footstrike. Forefoot flex is middle of the road. It is a neutral platform with no built-in correction.

Fit, sizing & life

The toe-box is wide, with space for the toes to spread late in long runs. It fits true to size. Expect roughly 300 miles from the outsole, about $0.77 per mile at $230.
