One look at the purpose-driven Assos rain bootie and you know it's all business. This pure rain bootie features a thin and low volume EVA KANT water resistant fabric, which is pattern cut to match the contours of your leg and foot. In a turn of events, Assos essentially turned the bootie inside out, by placing the protective membrane on the inside of the shoe cover and seam tape on the outside. While a tad unusual to look at, this makes for the ultimate seal from the outside environment. Pro Tour tested.
