Both my daughter and I loved these shoes. The final issue that I have experienced is that the fabric holding the strap on my right flip flop broke. Holes are all precise to access USB-C charging port and LED battery indicator. Quick and easy tapestry hanging. The strings are purely decorative not functional at all. 5 became 10. I?ve ordered 3 pairs in different styles in the last month. If I increase it anymore I can no longer hear anything but my tunes and the loudest of noises. I got a great deal on the black model - I guess no one wants black but I love it. Just enough to be annoying.
