How it rides

The foam

Altra tuned this midsole balanced (3/5 on our cushioning scale). Energy return is moderate — comfortable and predictable rather than bouncy. 29 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 geometry is fairly traditional and flat, so the shoe follows your foot rather than steering it. Forefoot flex is middle of the road. Support is light — neutral, with a mildly steady platform.

Fit, sizing & life

The toe-box is unusually roomy — foot-shaped rather than tapered, which suits splayed or bunion-prone feet. It fits true to size. Expect roughly 400 miles from the outsole, about $0.38 per mile at $150.
