The R1 is our first race shoe, built for multi-day road ultramarathon. Dual-zone ZeroSag™ inserts, co-developed with BASF, hold their shape deep into a long effort rather than degrading under repeated loading, while the LightCELL™ midsole base keeps the shoe light and lively underfoot.
GOFLOW™ midsole geometry guides the transition from heel to toe, and the double-layered jacquard upper, made with 40% recycled polyester, breathes through long hours on the road. The TUNEDFIT™ dual lacing system tunes the forefoot and midfoot separately, so you can lock the midfoot without cramping a forefoot that has swollen over the distance.

Mount to Coast publish foot length separately for the men's and women's ranges, and the two differ by about 5 mm at the same EU size. Measure your foot, then read the foot length column for the range you are buying. If you are between sizes, choose the larger size for better comfort.
Measuring your foot
You will need a piece of paper that fits your foot and a writing instrument to mark your foot's length. Having someone to help you with this could also be beneficial.
- On a hard floor, put a piece of paper against a wall.
- Stand on the paper in socks you would normally wear with this type of shoe.
- Ensure the back of your heel is against the wall and that you're placing your weight evenly on your foot.
- Ask someone to make a mark on the paper at the end of your longest toe.
- Measure the distance from the edge of the paper that touched the wall where your heel was to the mark at your longest toe. That is the length of your foot.
- Repeat this process on your other foot.
- It's common to have one foot bigger than the other, so make sure you measure both feet. Pick your shoe size based on the length of your longer foot.

Durability that ultrarunners trust.
Race proven
Records broken in the R1
JOGLE, spring 2024
Justin Montague
Before the R1 launched, British ultrarunner Justin Montague ran from John o' Groats to Land's End in a single pair: 1,374 km over 17 daily stages, almost 40 hours faster than the previous record, setting a new stage record every day.
World records, 2025
Meg Eckert and Matthieu Bonne
In spring 2025, Meg Eckert ran 603 miles (about 970 km) to break the women's six-day world record. Less than a month later, Matthieu Bonne covered 301 miles (about 484 km) to take the 48-hour world record, which had stood for 29 years.
