The Mount to Coast Men's M1 Trail Running Shoes – Moss are engineered for runners tackling long-distance trail races, mountain ultras, and demanding days in rugged terrain. Stable, highly cushioned, and built for a smooth, robust ride over extreme distances, the M1 combines responsive energy return with the support and traction needed when the trail gets technical.
At the heart of the M1 is Mount to Coast's next-generation JETCELL™ midsole foam, delivering the brand's highest energy return along with consistent performance built for serious mileage. Underfoot, a full-coverage outsole combines Vibram® Megagrip, Litebase, and Traction Lug technologies to provide predictable grip across steep, loose, wet, and challenging mountain terrain.
A wider platform, higher sidewalls, TUNEDFIT™ Dual Lacing System, and supercritical foam insole complete a trail shoe designed around the unique demands of ultra-distance running—helping you stay cushioned, stable, and comfortable as the miles continue to add up.
Finished in Moss, the M1 gets an earthy, trail-inspired look that feels perfectly at home in mountain environments while maintaining the clean, technical aesthetic of Mount to Coast footwear.
Next-Generation JETCELL™ Energy Return
The M1 features Mount to Coast's next-generation JETCELL™ midsole foam, engineered to deliver the brand's highest level of energy return while maintaining consistent performance over extended distances.
JETCELL™ provides twice the material strength of standard PEBA foams, creating a responsive yet robust cushioning platform designed to resist the wear and degradation that can come with serious trail mileage.
The result is an energetic ride built specifically for runners who need cushioning to continue performing deep into long training runs and ultra-distance races.
Stable Platform for Ultra-Distance Trails
Stability becomes increasingly important as terrain gets more technical and fatigue begins to accumulate.
The M1 uses a wider base and higher sidewalls to create a more stable, planted platform. This supportive geometry is designed to enhance confidence while navigating uneven surfaces, technical sections, steep climbs, and challenging descents.
A substantial 38 mm heel and 34 mm forefoot stack provides plenty of underfoot cushioning while maintaining a balanced 4 mm heel-to-toe drop.
Triple Vibram® Technology for Mountain Traction
The M1 features a full-coverage Vibram® outsole combining three specialized technologies for dependable performance across demanding mountain terrain.
Vibram® Megagrip provides tenacious traction across challenging surfaces, while Vibram® Litebase reduces outsole weight without sacrificing essential performance.
Vibram® Traction Lug technology adds specialized micro-features designed to further enhance grip and traction.
Combined with 4 mm lugs, the outsole delivers the versatility needed for changing trail surfaces and unpredictable mountain conditions.
TUNEDFIT™ Dual Lacing System
Mount to Coast's TUNEDFIT™ Dual Lacing System provides independent adjustment across different areas of the shoe.
The system allows runners to separately customize the forefoot and midfoot fit, making it easier to fine-tune security and comfort based on terrain, personal preference, and changes in foot shape over extended distances.
That adjustability is especially valuable during ultramarathons and all-day trail efforts, where the fit you want early in a race may not be the same fit you need many hours later.
Supercritical Foam Insole
Inside the M1, a supercritical foam insole provides another layer of responsive cushioning.
Working together with the JETCELL™ midsole, the insole enhances both energy return and underfoot comfort, creating a layered cushioning system designed specifically for extended trail efforts.
Durable, Breathable TPEE-Blended Upper
The M1 uses an upper constructed with TPEE-blended yarns, balancing the robustness required for demanding trails with breathability and quick-drying performance.
The upper is designed to provide stability and durability for long, rough races while remaining adaptable enough for extended wear.
A reinforced toe box adds protection as fatigue sets in and navigating rocks, roots, and other trail obstacles becomes increasingly challenging.
High Cushioning Without Excessive Weight
Despite its substantial stack, stable geometry, and full-coverage Vibram® outsole, the M1 weighs approximately 9.7 oz / 275 g in a men's US size 9.
That balance makes it possible to combine high cushioning, dependable traction, and long-distance stability in a package that remains performance-focused for trail racing.
Forged Through Ultra-Distance Competition
The M1 was developed with extreme ultra-distance racing in mind.
In 2025, ultra-runner Manu Vilaseca wore early M1 prototypes while breaking the women's record for the Triple Crown of American 200s by more than 29 hours.
That demanding real-world testing reinforces the M1's focus on one of the most important qualities for extreme-distance trail running: maintaining a stable and dependable platform as terrain becomes difficult and fatigue accumulates.
Fit Recommendation
Mount to Coast recommends ordering the M1 a half size larger than your usual shoe size.
That sizing recommendation is especially important to consider for runners planning long-distance and ultra-distance events, where additional room can become valuable as hours and miles accumulate.
With its combination of next-generation JETCELL™ cushioning, stable wide-base geometry, TUNEDFIT™ adjustability, triple-technology Vibram® outsole, and supercritical foam insole, the Mount to Coast Men's M1 Trail Running Shoes – Moss are purpose-built for runners pushing farther into demanding mountain terrain.
