the fact that I can shower with these is crazy cool***READ UPDATE IF YOUR SAMSUNG KEEPS DISCONNECTING THESE *****I noticed that my samsung s21 keeps disconnecting these after a bit of inactivity. As you can see, the sole has already detached from the rest of the shoe. My husband took his Dremel tool to them to sand the little nubs off. So I ordered a size 7. Very disappointed that the quality of this Reef sandal has lowered substantially over last pair purchased a few years ago. They fit perfect and comfy. Pide la talla usual. Die Schuhe, die als Geschenk gedacht waren wurden in der Falschen Größe geliefern. It is a story of fear. So this may indicate that the issue is software/firmware related and it could be fixed via a firmware update.
