5 but can fit into 7s and 8s as well depending on how things run. Almost hollow, mushy feedback with noticeable pre- and post-travel. its not a bad thing but you might want to try these on at a sketchers outlet. Hung a previous mirror with thicker and higher quality wire, this wire was a lot thinner than the other. The shoe was technically the correct size, however the strap that goes over the top was too tight. Very lightweightComplicated to put together because materials are so cheap. It has amazing sound quality for the price. They are very comfortable to wear but unfortunately they dont last long. I need a pair of easy-slip-on black sandals, and these fit the bill - theyre worth the money. Tried several different brands before finding this pair.
