Hike. Scramble. Run. Walk. Merrell has stretched the limits of what one shoe can do. Waterproof and breathable GORE-TEX gasket construction and GORE-TEX XCR lining keep your feet dry when it's wet, cool when it's warm, and warm when it's cool. These shoes provide extreme comfort and inspire envy. A four-way stretch collar of Lycra, neoprene, breathable mesh plus elastic lacing makes for the perfect fit, with easy on and off.
