We've always found it odd that sandals are the de facto standard for beach footwear and yet if you get them wet their footbeds stay soaked, leading to heel blisters, unidentifiable smells, and more. Reef XS1 Sandals ($60) overcome this problem via an ingenious integrated water drainage system that sends water through holes in the footbed and out through the open cushioning system, letting your feet dry while the bottom-mounted bottle opener keeps your mouth wet.
