Light trail-runner has soft Cushlon 3.0 foam and enhanced grip. The Kiger 10 is one of the lightest trail running shoes we've ever made. Its lean, low-profile design combines with a steady outsole so you can make quick, agile moves on technical trails. Stay Sticky - Vibram exclusive Kiger outsole made with Vibram Megagrip has a diverse lug pattern highlighted with wide spacing. Focused traction in high-wear areas helps reduce the shoe's overall weight. Cushioned Ride - Cushlon 3.0 foam midsole provides cushioning and underfoot support in a low-profile design. Keep Rocks Away - The forefoot rock shield is an added layer of support between you and your foot when you encounter rocks and trail debris.
