Flip-flops all seem to be made for ordinary/narrow feet, which makes them sit angled and hlf my heel would be off the sole. Unlike other slippers Ive had, my feet dont sweat in these so they seem to breathe well while still keeping my feet warm. I bought these for costuming purposes, and they work out great with my clown and mime costumes! With regard to the Bluetooth functionality, these paired easily with everything I attempted to pair them with. Something is different about this formula that my entire body reacted to and I am not someone that normally has issues with allergic reactions. The optical switches are 5x worse than the original Viper Ultimates, and now that Razer has tweaked those this is a mile behind. Other days I felt that the book was a big disappointment, and there was no way I was going to read any more in the series. Absolutely love this band/case combo it?s very chic and will go with any outfit. Beautiful model The width is perfect on me.
