C1 Womens
The C1 is our super trainer, built to make every mile more fun. Its dual-layer midsole pairs a top layer of CircleCELLâ„¢ foam, crafted from sustainable materials, for responsive cushioning, over a rubberised base layer that adds support and stability underfoot.
A wider base and higher sidewalls keep you steady deep into long runs, while the TUNEDFITâ„¢ dual lacing system lets you tune the forefoot and midfoot separately for a locked-in fit. Built for long-distance and multi-day efforts, recovery days and tempo runs alike.
EU sizing is the common scale across the range. Find your EU size and read across for the US equivalent in the range you are buying.

Mount to Coast publish foot length separately for the men's and women's ranges, and the two differ by about 5 mm at the same EU size. Measure your foot, then read the foot length column for the range you are buying. If you are between sizes, choose the larger size for better comfort.
You will need a piece of paper that fits your foot and a writing instrument to mark your foot's length. Having someone to help you with this could also be beneficial.
Road super trainer
The super trainer built for ultra distances.
Trains in the C1
Belgian record breaker Matthieu Bonne has made endurance his speciality across swimming, cycling and running, and took the 48-hour running record in 2025. He prepares at altitude in Kenya, where his schedule often stacks back-to-back 100 km days. That is the kind of training load the C1 is built for.
The highlights
Energised
A generous layer of CircleCELLâ„¢ foam sits over a rubberised EVA base for a stable platform. CircleCELL is the same supercritical foam used in the H1, with energy return on par with PEBA and up to twice the lifespan.
Stable and light
A wide, stable stance and a dual-layer midsole at 267 g (men's US 9). Built to let you push speed and distance in training so race day feels easier.
Tune in
Set forefoot and midfoot fit separately and adjust on the go as your feet swell over long distances.
Colour story
Training is a balancing act: enough load to come back stronger, not so much that you break. Pulse takes its cue from the red line every runner rides when they test their limits.
The top bragworthy features
