Mount to Coast says:
Stable, cushioned and built to offer a smooth, robust ride in the longest trail races, the M1 is optimized for the mountains. It features our next-gen JETCELL midsole to deliver unmatched energy return, and a full-coverage outsole with a trio of Vibram technologies for predictable grip in extreme situations.
In 2025, Manu Vilaseca broke the women's record for the Triple Crown of American 200s by over 29 hours, wearing early prototypes of the Mount to Coast M1. "Stability is what makes you go faster when things get complicated," she says, "and the M1 had that right away."
Hit the Jets. By applying a state-of-the-art supercritical foaming process to automotive-grade materials, we engineered JETCELL. The resulting midsole delivers our highest-ever energy return while boasting consistent performance and twice the structural strength of standard PEBA foams, resisting tearing and degradation from the first mile to the last.
Tuned for Chaos. The M1 upper is made with TPEE-blended yarns that provide the robustness and stability you need for the longest, roughest races, while drying fast and offering excellent breathability. We know feet change shape over extreme distances, so our TUNEDFIT Dual Lacing System offers independent, customizable fit for the forefoot and midfoot, and a reinforced tow box protects your feet when fatigue sets in.
Vibram's Finest. The M1's outsole features a trio of Vibram innovations: full-coverage Megagrip rubber for tenacious traction in any conditions, Litebase for 30 percent less weight without compromising performance, and Traction Lug micro-features for up to 25 percent more grip.
