Reef has created the Dram Sandal that can hold up to 3 ounces of liquid in its body. Well nobody knows why, maybe it's for those who can get lost on the beach. Anyways the sandals look great and they can still hold fluids.
The pair of such sandals will cost you about $ 45 and be sure you will be the geekiest person on the beach and everywhere around. People who will see you pouring soda from your shoe into a glass might think different things, even those who would know that this shoe is specially designed for that.
Besides, after walking on a beach the whole day your sandal will not be very clean and some sand particles can get into your glass. So I think that these sandals are for emergency cases. Well this is why they are called gadgets. They are cool and practically useless.
