How it rides

The foam

Mount to Coast tuned this midsole balanced (3/5 on our cushioning scale). Energy return is above average: the midsole rebounds well without feeling unstable. 36 mm of heel stack is the modern daily-trainer sweet spot — enough foam for long miles without losing contact with the road. 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 low 4 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. Forefoot flex is middle of the road. Support is light — neutral, with a mildly steady platform.

Fit, sizing & life

The toe-box is wide, with space for the toes to spread late in long runs. It fits true to size. Expect roughly 350 miles from the outsole, about $0.51 per mile at $180.
