Men's R1

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. 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.
