Reef created a two in one product—a flip flop with a bottle opener embedded in the sole of the sandal. They augmented the function of the sandal and by doing so changed the meaning of the product. It is not just a means to protect your feet and get around; it is a means to a good time! Oakley also features a two in one product—sunglasses with a built in MP3 player. They are so anti-ear bud and this product solved the problem of: “Do I wear headphones or sunglasses?”
