Ive used many, many wireless gaming headsets over the years. Molded to my foot very well. I charged it once when i got my hands on it. However, I’ve never been able to wear a 7 in any shoe! Works for connecting my old turtle beach X12 ear force (made for Xbox 360) to Xbox one controller with adapter. I am a 36DD (bought a Large) and this holds me in place through my workouts. But like I said, I have a high arch I need an insert, these shoes are specifically for the water and do an absolutely perfect job! Safety hazard for your toddler. The shoe was really cute, shipping fast and ordering process was seamless. Besides this issue, theyre great little speakers.
