How it rides

The foam

The midsole is PWRRUN, tuned soft (4/5 on our cushioning scale). Energy return is above average: the midsole rebounds well without feeling unstable. 36 mm of heel stack is the modern daily-trainer sweet spot — enough foam for long miles without losing contact with the road. 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 6 mm drop is the mainstream middle — familiar to almost anyone coming from a standard trainer. The rocker is moderate — enough curve to smooth the roll-through without dictating your footstrike. The forefoot is stiff, so it rolls rather than bends — a lever, not a slipper. Support is light — neutral, with a mildly steady platform.

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 450 miles from the outsole, about $0.36 per mile at $160.
