R1p up the Record Books

In the spring of 2024, British ultrarunner Justin Montague took one pair of R1s to the northernmost point of Scotland to run the JOGLE, a multistage ultra to the most southerly tip of England. Over 17 daily stages he ran 854 miles (1,374 km) setting a time that was almost 40 hours faster than the previous record, and he broke each day’s individual stage record along the way.

Experience the Consistency

To create the smoothest possible ride, Mount to Coast looked to the automotive industry to create ZeroSag, our groundbreaking midsole insert co-developed with BASF. Durable, comfortable and offering impeccable energy return at any temperature, ZeroSag guarantees extraordinary cushioning on the longest runs.

The Road to Enlightenment

LightCELL, our proprietary midsole base material, starts as a unique PEBA-hybrid compound before being charged with pure nitrogen to create a supercritical foam. The result is a material that is 50 percent lighter than EVA, while offering 45 percent more energy return.

Stay in the Flow State

GOFLOW is our industry-leading midsole geometry, designed to keep your feet tracking from heel to toe. With GOFLOW, you can stay in that flow state for longer, and enjoy your natural stride.

Tune In, Stride Out

In the relentless pursuit of distance, ultrarunners often encounter swollen feet. With the R1, your toes can relax and enjoy the ride thanks to our wide toe box and broad platform, and the TUNEDFIT Dual Lacing System offers customizable fit for the forefoot and midfoot separately.

Lighten the Load

The R1/R1R provides runners with the low weight required for performance, with all the protection they need to run day after day in the longest ultra challenges.

Breathe Easy

The double-layered jacquard fabric combines outstanding softness and perfect fit for your feet. And you can breathe easy in the knowledge we use 40 percent recycled polyester.

The best ever

I pulled these babies out of the box and thought I was going for a 3 mile test run. They felt so good, I decided to go for 10 miles. I took them up a hillside, on pavement and gravel and they felt amazing. The only part of me that didn’t hurt the next day was my feet. I will be a repeat customer.

Ultra marathon 100 miles

I ran 100 miles trails in R1! Unbelievable but true. I usually get 2-4 blisters at my usual hot spots but not this time. Tesla Hertz 100 miles is somewhat of an easy trails mostly roots and flat. Although I brought a few other shoes with me but I did not need to change shoes at all!
Amazingly comfortable and legs were not trashy after the race! The duo lacing system is such a brilliant idea!
Photos attached. One was during the race and the other was after the race.

First pair

I genuinely do not write reviews about something 1st day of owning, however this pair of shoes, are something to write about. A lot of company’s seem to be all hype due to social media, so it is difficult at times to navigate the turmoil of BS you see online. I’m confident in saying that given the price point and the hype, these shoes are everything I hoped they would be. Comfortable, functional, stylish, and true to size. Most importantly they’re like walking or running on a cloud. Will update again in 6 months, I’ll make good use of them given I work in a hospital, and my extra curricular fitness lifestyle of hybrid training.

Blown Away

Rarely would I try sneakers after just reading about them online. For the comfort, performance, and price point, the R1s can’t be beat. Great to see a newcomer to the market with this strong of an entry!

Perfect

I have no complaints about this shoe. I have never been happy with a running shoe, but then I tired these. I thought they were a gimmick, but they live up to their reputation.
