Mount to Coast Womens R1

Mount to Coast R1 is built to go the distance — whether you’re chasing your next PR or tackling a true ultramarathon. Its nitrogen-infused LightCELL midsole delivers a feather-light ride with strong energy return, while dual-zone ZeroSag inserts maintain plush, consistent cushioning even during 50-mile days. The GOFLOW midsole geometry and wide toe box encourage a smooth heel-to-toe transition and natural stride, making long miles feel easier. Combined with a breathable, recycled-poly Jacquard upper and adjustable TUNEDFIT dual-lacing system, the R1 gives you a custom, comfortable fit that stays stable from start to finish.
