Weighing in at just 7.4 ounces (M9), it has that barely-there feel that makes you forget you're wearing anything at all. The adjustable heel and instep straps let you dial in a snug, secure fit, so whether you're jogging along the shoreline or heading into town after a swim, the sandal stays where you put it.The 6mm FeelTrue® rubber sole is flexible and durable, with a dual-direction chevron tread that gives you solid grip on a variety of surfaces. At 6mm, it offers just enough protection underfoot while keeping you connected to the ground - great if you appreciate natural sensory feedback when you move. The smooth, tubular nylon webbing is made from post-consumer recycled water bottles, and all materials are 100% vegan-friendly, so the Z-Trek is as thoughtfully made as it is functional.Why Our Fit Experts Love This Shoe""I took these out on a beach walk and then wore them straight into a coffee shop after - no issues at all. The straps are easy to adjust on the fly, and the sole gives you enough feel underfoot that you actually notice the ground beneath you. If you like that minimal, connected feel, these are a lot of fun to wear."" - Dave, Road Runner Sports Fit Expert, San Diego, CAWho It's Best ForIf you're looking for a men's sport sandal that handles water activities, light jogging, and casual wear without missing a beat, the Z-Trek is worth a look.
