This unique shoe will help you take on long road runs and tough trail scrambles alike. Its wave-patterned midsole ensures comfortable cushioning for higher mileage excursions, and also helps shed weight by integrating the high-traction lugs into the design of the shoe, helping reduce the need for more rubber. This weightless feel is also felt in the upper, which uses highly-breathable materials to keep your feet cool and feeling free on hot days. Customer feedback suggests this shoe runs small, we would suggest sizing up if you are unused to a tight performance fit.
