Mount to Coast S1

Mount to Coast S1 review: what runners say

Fit

Narrower fit compared to the R1: suited to narrow-profile feet. Toe box wide enough to accommodate ultramarathon swelling; well-padded heel collar with good lockdown.

Feel

PEBA midsole with a dry, responsive feel — not soft. The polyurethane ZeroSag insert adds stability in the later stages of a run without over-softening the ride.

Durability

Estimated 500+ km thanks to the ZeroSag insert engineered for long-term resilience; outsole tested on wet surfaces with adequate traction. No precise km data from sources.

Best for

Daily trainer for high mileage and road ultramarathons. Suited to runners looking for a light, versatile shoe without extreme pace specialization.

Weak points

The toe cap can cause issues over ultra distances due to foot swelling. The ZeroSag insert produces an audible click on every stride, noted as irritating by at least one tester.
