Merrell takes minimalism to the trails with the Mix Master. With a 4 mm heel-to-toe drop, this lightweight trail running shoe is not low enough to be part of Merrell's barefoot family. However, it does prove to be a close relative. It has an extremely flexible outsole with sticky rubber for traction. The bottom of the foot is supported by an air cushion in the heel and a shock absorption pad in the forefoot. The Mix Master keeps things cushioned without weighing you down. Its Merrell Float midsole is 10 percent thinner and 25 percent lighter with more feel and ground control. Get closer to the trail today.
