Adventure to the less-traveled high country with Simms’ weight-shedding, pathbreaking Flyweight Boot. Weighing in at a spry 40 ounces, the boot’s low-profile design and breathable, abrasion resistant mesh uppers turn long miles and technical terrain into a cakewalk. And when you step into that brilliant, untrammeled water, Flyweights maintain full wading-boot stability and functionality, with reinforced felt soles for stud and cleat retention.
