How it rides

The foam

Asics tuned this midsole firm (2/5 on our cushioning scale). Energy return is moderate — comfortable and predictable rather than bouncy. 22 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 tall 9 mm drop tips weight forward off the heel, which usually suits heel strikers and calves that dislike low-drop shoes. The geometry is fairly traditional and flat, so the shoe follows your foot rather than steering it. 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 runs small; most runners size up a half. Expect roughly 250 miles from the outsole, about $0.44 per mile at $110.
