LOVE that its safe, all-natural ingredients because the cat will inevitably lick it off. I would like a refund or a new pair that is in good condition. I always wear slippers in the house to give extra support. She didnt have to put her feet on my back. Unfortunately I used it for two hours straight and it died on me. I didnt even use it in water or do anything that could cause it to break, it just stopped midway when i was listening to a song at work. Sounds incredible and I can feel the strong low frequencies and fairly clear highs. These get the job done so long as you are willing to put up with the quirks. They are very comfortable, and pretty cute for comfort shoes! If you look at the picture for the 16" model which I ordered it shows it being almost like a big U shape or V shape.
