No wonder that mountaineering-shoe specialist Five Ten produced a hiker that excels at scrambling and smearing. But testers were stunned by the Insight’s grip in wet, icy stipulations, too. “I hiked 10,000 feet down and back at the snowy South Kaibab Path,” says a ranger who didn’t even pull out his trekking poles. The unrivaled traction comes from a sole that blends Five Ten’s Stealth rubber (known for stickiness, but now not durability) with a more difficult rubber that stands as much as serious miles. SUPER CLEAN!
