Mount to Coast, a brand known for its high-quality endurance running shoes, has released the C1, a new super trainer designed for everyday comfort and durability. The C1 features a dual-density midsole with a top layer of Mount to Coast's proprietary CircleCELL foam and a bottom layer of rubberized EVA, providing a blend of cushioning and stability. With a 42mm heel and 36mm forefoot stack height, the C1 offers ample protection for long runs, while its wide platform and rocker geometry promote a smooth, efficient stride.

Why it matters

In a market saturated with max-cushion trainers, the C1 stands out with its focus on long-distance stability and durability. The shoe's sustainable construction, using recycled organic waste in the CircleCELL foam, also aligns with the brand's commitment to environmentally conscious manufacturing. The C1 aims to be a versatile workhorse that can handle daily training, long runs, and even some faster efforts, making it a compelling option for runners seeking a reliable, high-mileage shoe.

The details

The C1's dual-density midsole combines a softer, more responsive CircleCELL foam on top with a firmer, more stable rubberized EVA layer underneath. This blend provides a smooth, cushioned ride with good energy return, while the wide platform and rocker shape promote a stable, efficient stride. The upper features a breathable jacquard mesh with reinforced areas for durability, and Mount to Coast's signature TunedFit dual lacing system allows for a customized fit.

  • The C1 will be released on April 5, 2026.
  • Mount to Coast first previewed the C1 at The Running Event in December 2025.
