The list of shoes I trust for a genuinely long, rough day in the mountains is short, and it does not turn over often.
So I paid close attention when Mount to Coast, a brand that carefully built its name on road and multi-day ultras, released the M1, the most cushioned trail shoe in its lineup and the model it is aiming at races like Western States and UTMB.
The Mount to Coast M1 is the third trail-capable shoe from the brand, and it sits at the top of that range. The T1 is its lighter, nimbler trail shoe and the H1 is its road-to-trail hybrid, while the M1 is the max-cushion, all-mountain option built for the longest efforts. Travis Liles of iRunFar, who put more than 100 miles on a pair this summer, landed on the Hoka Speedgoat 7 as its closest comparison, a maximally cushioned shoe with enough grip and control to go almost anywhere.
The M1 went on sale August 10 at mounttocoast.com and select retailers in the US, Europe and Asia, with wider availability rolling out through September. It comes in three colorways, Moss, Glacier and Oatmeal, and retails for $195.
Mount to Coast built the M1 for the kind of runner who tacks on an extra summit or drops into one more canyon instead of calling it a day. The brand says prototype versions were on Canyon Woodward’s feet for his eighth-place finish at the 2026 Western States 100, and that early M1s carried Kilian Korth, Cody Poskin and others through the opening miles of the 2026 Cocodona 250.
At the center of the shoe is JETCELL, a supercritical foam that Mount to Coast builds from ATPU and calls its highest-energy-return foam yet, with twice the material strength of PEBA, the foam in many performance shoes. Liles put that durability claim to the test. After more than 100 miles across road, fire road and technical trail, he found no real creasing or pack-out in the midsole and said it kept the same bounce it had on day one. The M1 runs high and soft, with a 38mm stack in the heel and 34mm up front for a 4mm drop, and at 9.7 ounces for a men’s US 9, it carries that cushion without feeling like a lot of shoe.
For traction, the M1 uses a full-coverage Vibram Megagrip outsole with Litebase and 4mm Traction Lugs that bite on trail without feeling heavy on pavement. The platform is wider than the brand’s other models, and raised midsole sidewalls cradle the foot for stability on loose, off-camber ground. The upper is a light, breathable mesh that drains well, with internal bands that lock the midfoot in place, a padded tongue, a structured heel cup and a gaiter attachment. The M1 also carries Mount to Coast’s TUNEDFIT dual lacing system, a two-part setup that splits the shoe into separate forefoot and midfoot zones. A quick-pull lace handles the forefoot and tucks into a lace garage, while standard laces run through the upper eyelets, so you can keep the midfoot locked down while easing off the toe box as your feet swell, or re-tension one zone on the move without redoing the whole shoe. That is a real advantage over a long ultra, when feet spread and change shape by the hour, and it pairs with a wide toe box already built to give them room.
“We built the M1 for runners who choose to add an extra summit to their run, or choose to explore a new canyon instead of heading to the trailhead,” said Mount to Coast co-founder and head of product Yeti Zhang. The M1, he said, uses the brand’s most advanced midsole and a high stack to keep the ride comfortable and the shoe durable “for all the miles long distance runners desire.”
That durability claim is the thread running through everything Mount to Coast makes. Founded by a team of footwear engineers with an average of more than 26 years each at market-leading brands, the company spent roughly 18 months in development, won an ISPO Award for its R1 prototype in 2023 and began selling shoes commercially in early 2024. Zhang alone spent nearly six years at Nike and more than a decade at Brooks, where he was among the first engineers to work with supercritical foam. In the short time since launch, outlets from Outside to Gear Patrol to Trail Runner have singled the brand out as one of the more serious young contenders in running, a boutique operation whose foams and fit systems now rival the established players.
Mount to Coast’s R1 has carried runners to the men’s 48-hour, men’s 6-day and women’s 6-day world records, each set in a single pair of shoes. Several of those marks had stood for decades. The brand’s signature technologies became selling points in their own right, from ZeroSag, a cushioning insert co-developed with the chemical company BASF to fight midsole breakdown late in long races, to the TUNEDFIT dual lacing already on the M1.
The lineup is now seven shoes deep across road, hybrid and trail, more complete than most young brands could manage, and the M1 pushes that same durability-first engineering to the most cushioned trail shoe the company has made.
