All are essentially useless as a visual and audible tile finder. Taking advantage of high demand I will see what I can do and try to fix it. Instructions were clear. Love sanuks! I do a lot of walking and hate closed in shoes but find it difficult to get shoes/sandals to fit as I have a wide foot. No era para romperse como se rompió Really annoying. For like 12 bucks, these are such a great addition to my routine~ These slippers are very comfortable and easy to slide into.
