The Chaco Z/2 Unaweep Men's Sandal is probably the most secure sandal on the planet. Its Unaweep outsole is 20% lighter than Chaco's previous sandals, and it's ideal for activities that demand solid footing in or out of water. The Z/2 sandal's strap configuration offers an adjustable toe loop that adds a measure of security to your foot, making them incredibly stable. Whether you're a river rat who needs a super grippy sandal or you just want a sturdy, great-looking pair of sandals that will last ages, the Chaco Z/2 Unaweeps will last for years.
