Embrace the purity of running by sticking to the basics with Merrell’s Allout Rush, a minimalist running shoe that uses the barefoot principles of natural running— giving you an all-out rush the instant you put them on. This shoe adds more underfoot protection for running on harder, rougher surfaces, so you still get the feel of barefoot running, but your feet stay protected and stable. It’s crafted with a mesh upper for lightweight breathability, and TPU to make the shoe more flexible, durable, and abrasion resistant. A Merrell Omni-Fit lacing system gives you a precise, glove-like fit for personalized comfort, while a breathable mesh lining treated with M Select FRESH odor control keeps your feet protected against unwanted odors. A Uni-Fly midsole disperses impact and stabilizes your feet for a solid takeoff, while also providing high-mileage cushioning for longer runs. The M Select GRIP outsole offers durable traction that grips when and where you need it. Reflective details are included for enhanced visibility in low-light conditions. Wt. 9.0 oz.
