How it rides

The foam

Asics tuned this midsole balanced (3/5 on our cushioning scale). Energy return is above average: the midsole rebounds well without feeling unstable. 24 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

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 low 5 mm drop encourages a midfoot landing and keeps the ankle working through a fuller range. 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 standard width — comfortable for most feet without swimming. It fits true to size. Expect roughly 300 miles from the outsole, about $0.47 per mile at $140.
