The comfort of a sport sandal upper, and lightweight, barely-there feel of a packable sandal lets the Z-Trek do it all. The smooth, tubular nylon webbing is now made from post-consumer, recycled water bottles. Adjustable heel and instep straps let you fine tune for a snug fit. A flexible, durable 6mm FeelTrue® sole with dual-direction chevron tread provides great grip, and the just-right amount of protection and sensory feedback. Confidently go from jogging at the beach, to your favorite water-sport, and a stroll through town, all while enjoying the benefits of natural freedom.
