I highly recommend these slippers. Its totally unusable though. Tried the different styles of inserts that came with them but they won?t stay in. I keep having to buy these cause when people come over they steal them. The comfort level is fantastic as well as the vibration and sound quality. You can forward/reverse by holding the volume buttons. It isnt. Awesome You won?t regret getting this one! Con:Had to order a size 11.
