These sandals are extreme, comfortable and packed full of powerful features. Walk, run and even tread through water in the awesomely athletic X-S-1 sandal from Reef. The footbed has special drain holes so you don't slip, while a thicker, more high-tech heel area provides maximum support and shock absorption. The mini trampoline feature is a similar design to what you see in running shoes and provides stability as well as adds power to your stride. These super sandals also feature a bottle opener to quench your thirst after all your crazy antics. Seriously, you don't need any other sandal but this one — unless you want it in different colors.
