How it rides

The foam

Brooks tuned this midsole very soft (5/5 on our cushioning scale). Energy return is above average: the midsole rebounds well without feeling unstable. At 42 mm of heel stack this sits in max-cushion territory; legs stay fresher on long efforts, but the platform is tall. Combined, the ride reads as lively at 3/5 responsiveness.

The plate

There is no plate here. The midsole does all the work, so the shoe flexes naturally and stays versatile across paces — easier on the feet day to day, but without the snap of a plated shoe when you want to roll.

The geometry

A tall 10 mm drop tips weight forward off the heel, which usually suits heel strikers and calves that dislike low-drop shoes. 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. It offers real guidance through the gait cycle — useful for runners whose form collapses when tired.

Fit, sizing & life

The toe-box is standard width — comfortable for most feet without swimming. It fits true to size. Expect roughly 500 miles from the outsole, about $0.35 per mile at $175.
