Our tester celebrated how readily the Libero, with its contoured, ergonomic NestFIT system and deep heel cup, locks your foot into position, which gave great multidirectional support. He also noted the shoe’s abundant cushiness and soft suede uppers. He did, however, lament a lump under the arch that felt uncomfortable for his stride.
“Really supportive,” commented our tester, who took the shoes out on the steep, switchbacking trails in the Flatirons, “without much shifting at all.” He felt that the shoes would be well suited to trekking or long mountain approaches, given their stable platform and suction fit.
The Libero, with its Hypergrip Super Gum sticky sole, had great traction on scrambly terrain, while the Treksta Flex System imparted solid flex for smearing, though the rubber wasn’t as grippy as others tested. “A better sole design would go a long way,” our tester said, suggesting more flat climbing zones would improve sensitivity and edging.
