"Waterproof and affordable, great for everything from rugged dayhikes to major off-trail epics," says our tester after a jaunt through Yellowstone. Break-in is almost instant, ankle and underfoot support superb even on crumbly terrain, and durability top-notch, thanks to details like a thick rubber rand. His only wish: Better cushion for pounding out trail miles. For summer use, check out the nonwaterproof Pro Trek 5 ($100). Best for medium to wide feet.
