Mount to Coast M1 Trail Running Shoes - JETCELL Foam and Vibram Triple Technology for the Longest Races

Stable, cushioned, and built for a smooth, robust ride across the longest trail races. The M1 is optimised for the mountains, featuring next-gen JETCELL midsole for unmatched energy return and a full-coverage Vibram outsole with Megagrip, Litebase, and Traction Lug 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 M1 prototypes.

JETCELL Next-Gen Midsole Foam

By applying a state-of-the-art supercritical foaming process to automotive-grade materials, Mount to Coast engineered JETCELL. The resulting midsole delivers the highest-ever energy return whilst boasting consistent performance and twice the structural strength of standard PEBA foams, resisting tearing and degradation from the first mile to the last. A supercritical foam insole adds further energy return and comfort underfoot across ultra distances.

TUNEDFIT Dual Lacing System with TPEE-Blended Upper

The M1 upper uses TPEE-blended yarns for robustness and stability across the longest, roughest races whilst drying fast and offering excellent breathability. Mount to Coast's TUNEDFIT Dual Lacing System provides independent, customisable fit for the forefoot and midfoot separately, because feet change shape over extreme distances and a single lacing zone can't accommodate both. Reinforced toe box protects feet when fatigue sets in on technical terrain.

Wider Base with Higher Sidewalls for Stability

Wider base and higher sidewalls enhance stability during long runs on technical mountain terrain. As Manu Vilaseca puts it: "Stability is what makes you go faster when things get complicated, and the M1 had that right away."

Vibram Triple Technology Outsole

Full-coverage Megagrip rubber provides tenacious traction across any conditions. Litebase reduces outsole weight by 30% without compromising performance. Traction Lug micro-features deliver up to 25% more grip on technical terrain. Together, these three Vibram innovations create a confident outsole across the extreme and varied surfaces that ultra mountain racing demands.

Is the Mount to Coast M1 Right for You?

Built for runners who take on the longest, most demanding races where shoe performance across accumulated fatigue matters as much at mile 150 as it does at mile one. JETCELL foam with twice the structural strength of standard PEBA maintains its energy return character across ultra mileage that degrades lesser midsoles. TUNEDFIT dual lacing addresses the real challenge of foot swelling across extreme distances without compromising forefoot or midfoot security. Vibram triple technology handles unpredictable grip demands on extreme mountain terrain. Wider base and higher sidewalls keep things stable when fatigue makes every step harder. Validated by Manu Vilaseca's record-breaking Triple Crown performance, the M1 was built for exactly this level of ambition.
