How it rides

The foam

Adidas tuned this midsole soft (4/5 on our cushioning scale). Energy return is moderate — comfortable and predictable rather than bouncy. At 40 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 calm at 2/5 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 geometry is fairly traditional and flat, so the shoe follows your foot rather than steering it. Forefoot flex is middle of the road. 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 450 miles from the outsole, about $0.42 per mile at $190.
