Size Measuring Guide
A perfect fit for your ultra-marathon running shoes is important for comfort and performance. Follow these tips to measure your foot size at home:
General Tips:
- Measure your feet at the end of the day as they're at their largest due to swelling.
- In between sizes? One foot is bigger than the other? Take the larger size.
- It's best to measure every year. Your size could change over time.
What You'll Need:
- A piece of paper larger than your foot,
- A pen or pencil,
- A ruler or measuring tape,
- Socks of the thickness you'll wear with the shoes.
Steps:
- Stand on the paper in the socks you'll wear with the shoes.
- Use the pen or pencil to mark the end of your longest toe and the back of your heel. It's important to measure both feet as their size can vary.
- Match your measurements to our size chart to find the best fit. If you're between sizes, we suggest choosing the larger size for better comfort.

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."
Featured
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.
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 toe box protects your feet when fatigue sets in.
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.

Super!
Did a few miles before putting them to a suitable test. 110 km of harsh trail, M1 delivered.
Comfy, really good foam and grip and a very nice fit.
Had to go up half a size compared to T1 and H1.
Ma première commande, pourtant dans ma pointure habituelle toutes marques confondues, a nécessité une pointure supérieure. De plus, le laçage m'a coupé le pied, un problème que j'ai résolu dès ma deuxième sortie. La stabilité de la chaussure est horrible, donnant la sensation de courir sur une savonnette. Le pied bouge énormément de droite à gauche à l'intérieur, malgré un laçage intégral. Bien que j'aie le pied large, le mesh est beaucoup trop haut ou large, ce qui contraint à serrer excessivement les lacets, sans pour autant éliminer la sensation d'instabilité, particulièrement dans les sections techniques. Pour ceux qui talonnent en descente, cette chaussure est à proscrire, car elle part de droite à gauche. La hauteur de la mousse, sa verticalité et sa rigidité (sur les 100 premiers kilomètres) n'améliorent en rien cette impression d'instabilité. Cependant, la mousse s'assouplit au fil des kilomètres. Sa qualité est excellente sur terrain plat ou faux plat, où elle fait oublier les défauts mentionnés. L'accroche est également excellente. J'attendais énormément de cette chaussure, mais mes attentes n'ont pas été comblées.
Had these about a month and I’ve been on two long runs since. They’re feeling very stable and have stayed comfortable for the length of it. Obviously trying not to run on the road too much with them but even still they feel very cushioned for road. They don’t feel cheap either, giving me confidence to run harder, longer etc.
All in all, it’s a very solid shoe would recommend
Not too sure how much advantage there is in the more complicated lacing system but it all works fine.
Sizing is a tad under as I normally run to 12.5 or 13us.
Went the 13us and they are a tad small but I just get away with it. Maybe size 1/2 up. Other than that great vibram sole and really like the cushion feel on the mid. Nice and springing and also the overall weight is minimal so overall been a very good shoe so far.
Only done about 30kms in them so early days but no sign of any obvious wear at this point. Great effort M-C team 💪🏼🍻
Soy Asier , de España .
La zapatilla una vez puesta en los pies se sienten genial ; sujeción del empeine perfecta , lengüeta acolchada y espacio en los dedos . Sorprende que pese a todo se sienta muy ligera .
Quizás , por ponerle un punto de mejora , pese a haber medido 4,3mm en los tacos .., le daría un poco más . Sobre todo para la zona norte de España que es donde vivo .
De cualquier manera , una pasada de zapatilla
Vraiment j’apprécie le travail réaliser sur ce model je me sent a l’aise et en confiance dans toutes les situations merci 🙏
First real trail weapon for some years,
In past trail shoes had been dead but the M1 is a stable lively shoe that wants to move and no matter what speed you run this shoe will make you faster.
But gives added confidence with traction and overall fit comfort.
Love the shoes. Fit is great and it performs awesome. Used it once and decided to start an ultra with it. 5km into the race I had blisters on my Achilles and had to switch them out. Never had this with any other shoes so I’m hoping it’s not gonna happen forever and they just need to be broken in.
Great outsole and bouncy midsole. Smallish fit, would recommend going up a half size from H1 if you have that one, but still feels Great to run gravel roads and such in them.
Hola. Yo ya tenia las T1, de las que estoy muy contento con ellas. Mi primera impresion con las M1, fueron buenas, son muy comodas, pero al probarlas en el terreno durante una salida de 4 horas, note una pequeña molestia en la parte baja del hueso del tobillo, en las dos piernas, pero sobre todo en la izquierda en la que me produjo una pequeña herida. Tengo una carrera en un mes, y por el momento no las voy a probar de nuevo. Quizas estas nuevas medidas no se adaptan a mi pie, ya que con las T1 no he tenido nigun problema desde el principio. Un saludo.
Holy mother of shoes ! These are a true blessing ! My quest for the perfect trail show is finally over. I am not a runner but a seasoned thru-hiker and these are exactly what i was looking for. I am usually size 10 US border 9.5 so the M1 in 10 are a perfect fit for me. I could not be happier. The JetFoam is epic and breathabilty at it's best. I will probably get more in the futur. I'm in love with these shoes !
No llevo aun muchos kms con ellas, pero las primeras sensaciones están siendo espectaculares! Seguramente de las mejores zapatillas de ultra distancia que he probado
Zapatilla, muy cómoda desde el minuto 1, estable y con buena tracción con la suela vibram que no falla. Para ser la segunda zapatilla que sacan después de la T1, hats off
I put the Mount to Coast M1 through a pretty decent test — taking them up Snowdon / Yr Wyddfa, the highest mountain in Wales, on a very wet morning.
The conditions were far from ideal, with loose slate, wet rocks and plenty of slippery sections, but the M1s handled it brilliantly. The grip across the loose slate and wet stones was seriously impressive, and on the way back down I was able to go full send with confidence.
What really stood out for me was the stability and comfort. Even on uneven terrain, they felt incredibly planted underfoot, giving me plenty of confidence when things got sketchy.
I also absolutely love the stack height — it gives you that lovely cushioned feel without making the shoe feel unstable.
And finally… that colorway Glacier
I genuinely couldn’t have chosen a better one.
Wet mountain. Loose slate. Slippery rocks. Full send downhill. The M1 passed the test.
The Mount to Coast M1 has one of the best midsoles I've run on in a trail shoe, and what stands out is how reactive it stays even when the ground gets complicated. The Vibram outsole backs it up with exceptional grip, and the fit is toe-friendly, with real room up front. The upper is breathable and never runs hot, and the fabric is soft enough that it doesn't chafe or dig in anywhere; it feels closer to a road shoe upper than a typical trail one. My only complaint is the lacing, which I had to learn to use. What finally worked was pulling the upper laces down so they start where the lower ones, the pair nearest the toe, finish. Once I did that the shoe stopped rotating on my foot and felt much more secure on technical ground. Stability is very good throughout. On gravel you can run as fast as your legs will let you, and you can still move quickly through forest and more technical terrain. It climbs easily and descends fast as long as it's properly locked to the foot. It works both as a daily trainer and as a race shoe. I also run in the Prodigio Pro and the Tecton X3, and to me the M1 is the better shoe.
