Mount to Coast M1 - Women's

The M1 from Mount to Coast is your long-distance, mountain performance running shoe with heaps of stability and support for an all-day comfortable ride.

This is your big-mountain, all-day adventure, ultra-distance race shoe for when stability, support, and grip really matter - when fatigue starts to creep in and the finish line is in sight, the M1 will keep pushing you all the way.

Proof is in the pudding: 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."

Sizing: The M1 is quite generous in size, so we would recommend starting with your usual street shoe size.

Key Features

• Hit the jets
  By applying a state-of-the-art supercritical foaming process to automotive-grade materials, MtoC engineered JETCELL. The resulting midsole delivers its 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 the TUNEDFIT Dual Lacing System offers independent, customisable fit for the forefoot and midfoot, and a reinforced toe 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% less weight without compromising performance, and Traction Lug micro-features for up to 25% more grip.

• Podiatrist-approved
  Carries the APMA Seal of Acceptance, recognising the T1's support for good foot health.
