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.

Just ran a 100km in these. Tried just out of the box as felt so condortable. Lovely bounce and cushioning when needed and grip is very good

best shoes so far!
Just tried then on for a minute but love them already. They make me feel like going out for a run even though I just came back from a long run! I ordered my usual longer distance size (which is half size bigger compared to my daily trainers) but I can feel my toenails touching the front of the shoes (despite having really short toes compared to every single person I know) so I am going to get a half size bigger and just wear them with a thicker pair of socks. Fingers crossed it will work :)
I wanted to love these because I thought they would fit like my C1’s. Was disappointed, they are way tighter in the toe box. Also, they rubbed on the side of my big toe.
Bonjour, pourquoi ne pas avoir mis de semelle de propreté avec des trous comme sur la h1 ? Car lorsque l on court sous la pluie,herbe humide ainsi que transpiration la chaussure sèche pas vraiment ?
Bonjour Sebastien,
Merci pour votre question. La M1 utilise une semelle intérieure en mousse supercritique, un matériau qui n’absorbe pas l’eau. Il n’est donc pas nécessaire de la perforer comme celle de la H1. De plus, des perforations pourraient réduire sa résistance aux compressions répétées dans le temps. C’est pourquoi nous avons choisi de conserver une structure pleine.
