Ultralight Cushioning for Endurance and Efficiency
Mount To Coast R1 Women’s is engineered for long-distance runners who demand lightweight comfort, energy return, and lasting support. Designed with marathoners and ultrarunners in mind, this model blends innovative midsole technology with a breathable, adaptive fit for high-mileage performance.
The double-layered jacquard upper adapts to your foot while offering breathable structure. Made with 40% recycled polyester, it supports sustainability without sacrificing durability. The TUNEDFIT Dual Lacing System allows separate adjustment for the forefoot and midfoot, ensuring a secure fit that adapts as your run progresses.
The LightCELL midsole uses nitrogen-infused foam to deliver bounce and reduce weight. It’s 50% lighter than EVA and returns 45% more energy. ZeroSag inserts, co-developed with BASF, resist compression and maintain cushioning over long distances. GOFLOW midsole geometry guides your stride from heel to toe, helping you stay in rhythm.
The wide toe box and broad platform accommodate swelling and promote stability. A CPU outsole keeps the shoe light while offering traction on paved surfaces. With an 8 mm drop and a weight of 8.5 ounces, Mount To Coast R1 Women’s supports smooth transitions and long-lasting comfort.
Mount To Coast R1 Women’s is ideal for runners tackling marathons, ultramarathons, or high-mileage training blocks. It’s engineered to reduce fatigue and keep you moving efficiently, mile after mile.
