Bonne to do it.

Matthieu Bonne is a professional record breaker. From swimming to cycling to running, he’s made endurance his superpower – he even has the record for the most basketball free-throws in 24 hours. When he’s targeting a running record, like the 48-hour record he broke in 2025, Matthieu retreats to Kenya, where the altitude and simple life make for productive training. Known for his incredible mileage, Matthieu’s schedule often calls for back-to-back days of 100 km – precisely the kind of extreme training where the C1 excels.

The super trainer, energized.

The C1 features a dual layer midsole, utilizing a generous layer of our sustainable CircleCELL foam above a rubberized EVA bottom layer that provides the stability you need to go beyond. CircleCELL is the same supercritical foam used in our award-winning H1, delivering energy return on par with PEBA-based foams, while providing double PEBA’s running lifespan.

Stability, elevation, enlightenment.

Despite its wide, stable stance and dual-layer midsole, the C1 comes in at a feathery 9.4 oz / 267 g (US M9), because long distance performance shouldn’t weigh you down. Featuring a 42 mm stack height and 6 mm drop, the C1 is optimized to let you push your limits of speed and distance in training, so that race day comes easy.

Tune in, don’t drop out.

The TUNEDFIT Dual Lacing System offers separately customizable fit for the forefoot and midfoot. Because we know that in the ultrarunner’s pursuit of distance, feet can swell and change shape, and having a shoe that can adapt to those changes on the fly can be the difference between minor discomfort and injury. With TUNEDFIT you can enjoy the ride and channel your focus to the miles ahead.
