To help you push your limits, this low-profile shoe employs a durable and high-traction Vibram MegaGrip outsole. A premium EVA Foam cushioning offers powerful energy return with every step, while also being 30% lighter than standard EVA. We removed the membrane for those who like to hike in warmer drier climates, to focus on a cooler experience with more air movement. The engineered seamless upper construction with soft materials reduces pressure points and keeps you comfortable. The collar around the ankle comfortably encloses your foot within the shoe while preventing dirt and debris from getting trapped inside. Maximum cushioning creates an easier experience for joints and reduces fatigue on high-mile treks.
