"Although equals in terms of comfort, durability, and waterproof design, the Salomon Quest 4D improves upon the brand’s X Ultra shoe with a heavier, grippier outsole and advanced stability and ankle support, making it a great pick for tougher hikes that require shouldering heavy packs, like New Zealand’s Routeburn Track. These boots aren’t built for your average neighborhood day hike, but will carry you through any serious expedition—off-trail hikes, steep climbs and descents, multi-day journeys through mountain passes—with ease."
