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.

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.

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.
A force d'entendre parler de cette chaussure et des autres modèles, j'ai commandé cette paire directement sur le site. J'ai environ 100 km de chemins techniques, gravel et un peu de route. L'empeigne est très confortable, respirante et sèche rapidement et la languette bien rembourrée. J'ai enlevé le système TUNEDFIT (peut être trop compliqué pour moi en tous cas pas adapté pour mon pied) et j'ai mis des lacets normaux (ça s'adapte bien). La semelle est ce qui se fait de mieux, beaucoup de répondant, très confortable mais pas mou. C'est assez haut et dans les parties techniques, au début, ça semble instable. Mais après 100 kilomètres, on est plus à l'aise et la chaussure s'assouplit donc il faut compter avec une période break-in. En fait, plus je la porte et plus elle est agréable. J'avais l'habitude de changer de chaussure à chaque sortie mais avec celle là, j'ai couru avec chaque jour depuis qu'elle est sortie de sa boite. Les crampons sont parfaits et sont à l'aise partout. Petit bémol dans la boue collante, la semelle débourre moyennement. Sur toutes les autres terrains, et même la route, c'est parfait. Je ne note aucune usure pour l'instant alors que je mange souvent les crampons au talon. Le coloris Oatmeal devient rapidement sale et c'est nickel ! J'adore cette chaussure. Elle est quasiment parfaite et je vais faire quelques mois avec à l'entraînement et en course. Bravo à Mount To Coast d'avoir créer cette chaussure simple, efficace et si confortable. Je pense qu'elle est fait pour les Ultras et que l'on peut s'entraîner tous les jours avec.
The M1 is exactly what I have been waiting for
The cushion is these is superb the grip for muddy and technical terrain is amazing
Great work Mount To Coast team. 👏
I now have 4 pairs for all various surfaces.
What a brand 👌
Las he utilizado unos 30 km. Son espectaculares, cómodas y reactivas a velocidad media.
Ultimate comfort straight out of the box. I took the Mount to Coast M1 straight into an 18-mile run across mixed Scottish terrain with some road thrown in, and they felt excellent throughout. The cushioning is soft, springy and forgiving, and they just seem built for long-distance miles. I’m still not completely sold on them for really technical ground, but for ultras and long days out, they feel like a very strong option. I’ll be wearing them for my next 70 km ultra.
Las zapatillas son súper estables, muy buen agarre, muy comodas, no podría sacarles ni un solo defecto. Un 10 en todo, la verdad.
Primera semana con 100km i 7000+ impresionante la comodidad que dan a tus pies.
Enhorabuena por esta maravilla.
Excellent straight out of box
Incroyable service client. Javais commandé la mauvaise taille, ils ont reussi a intercepter la commande et à me renvoyer la bonne taille sans attente supplementaire
Prevoir 1/2 size up pour le trail.
Hey, in New Balance, Altra and Asics my size is 42. What size would you recommend in the M1 Modell?
Thanks and have a nice day.
Best Max
Hi Max, the M1 has a slightly snugger fit compared to the H1 and T1. Based on our recent customer feedback, we would recommend going half a size up for the best fit in the M1.
