What good is waterproof when your feet are sitting in a puddle of sweat? The new Lone Peak Neoshell is made of a revolutionary new fabric that's waterproof on the outside yet breathable from the inside. It's designed to fight off water and release heat to keep your feet cool and dry. The FootShape™ toe box lets your toes relax and spread out naturally for greater stability and comfort in shifting terrain. Flexible StoneGuard™ rests above the midsole to deflect sharp, jagged rocks from digging into your feet.
