Mount to Coast
C135 Mens
Each July, the Badwater 135 gathers 100 men and women from across the globe to run across Death Valley and up three mountain ranges to high on Mount Whitney, widely considered the world's toughest foot race. The C135 is our special edition C1, tailored to that challenge.
Built for races in extreme heat, it pairs the C1's dual-layer CircleCELL™ midsole, crafted from sustainable materials, with an ultralight, breathable, fast-drying woven mesh upper engineered for the desert. A reflective midsole coating adds low-light visibility, and the TUNEDFIT™ dual lacing system tunes the forefoot and midfoot separately.
EU sizing is the common scale across the range. Find your EU size and read across for the US equivalent in the range you are buying.

Mount to Coast publish foot length separately for the men's and women's ranges, and the two differ by about 5 mm at the same EU size. Measure your foot, then read the foot length column for the range you are buying. If you are between sizes, choose the larger size for better comfort.
You will need a piece of paper that fits your foot and a writing instrument to mark your foot's length. Having someone to help you with this could also be beneficial.
