How it rides

The foam

Asics tuned this midsole firm (2/5 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 snappy at 4/5 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 6 mm drop is the mainstream middle — familiar to almost anyone coming from a standard trainer. 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. It is a neutral platform with no built-in correction.

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 200 miles from the outsole, about $0.65 per mile at $130.
