How it rides

The foam

Topo Athletic tuned this midsole firm (2/5 on our cushioning scale). Energy return is moderate — comfortable and predictable rather than bouncy. 18 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 0 mm drop is close to level. That loads the calf and Achilles more than most runners are used to, so ease into it. The geometry is fairly traditional and flat, so the shoe follows your foot rather than steering it. The forefoot flexes easily, so the shoe adapts to slower, shorter strides. Support is light — neutral, with a mildly steady platform.

Fit, sizing & life

The toe-box is unusually roomy — foot-shaped rather than tapered, which suits splayed or bunion-prone feet. It fits true to size. Expect roughly 300 miles from the outsole, about $0.42 per mile at $125.
