The wider shoe fixed the tight heel cups. Finally, the shoe does not have a wide enough toe or heel base. Cute and good quality. I am letting you know all of this so that you know whose review you are reading. Sound quality is crisp and clear with a moderate amount of bass. They were so annoying but I read that you need to break them in, and make the strap tight. I drilled pilot holes in the wall and stud to make screwing the lags in easier, and to safeguard the integrity of the wood. The sound is good, but mine dont unpair when I put them in charging case. Definitely order one size smaller than what you wear. As of this moment Im not sure if I will look to them for another purchase.
