My ONLY complaint is the cost. This sandals fit very nicely the problem I did have is that I have purchased a size 6 before and it was too small so I had was to contact the seller to let them know and they advise to get a size 7 which I did and the size 7 fit perfectly even though I and a size 6 in most of my shoe this size 7 fit great so please get 1 size up The mechanism with the hook acting as a suction lever too is kind of genius. I had a mix of software routing, ran it through a processor and interface. They are also very comfortable and I like the option to keep the ankle strap up for easy on/off options or to place it on the ankle for a more secure fit while outside. Prefer to have them work individually and this is exactly what I was looking for. These still look brand new after I threw them in the washer yesterday. These are perfect for listening to music En realidad ahora uso éste todo el tiempo. PREMESSA ??Il prodotto l?ho acquistato, non l?ho ricevuto come prodotto dimostrativo gratuito.
