Fun fact, this thing is collapsible. I would be not very smart to not purchase these again, if I ever need slippers again I have had no technical issues with it at all. They fit true to size as far as length of the shoe, just wish the strap would get a bit tighter. The microphone isnt amazing but in my experience with other earbuds none of them are great. If I wanted shoes this bad, I?d buy them from Walmart for much cheaper. I own about 10 pairs of Fitflops. It was the work of a moment to unclip the old ones and replace them with the pristine ones. I love the Spigen stuff and this is good but its just not perfect. Weve found these shoes to be comfortable, durable, and easy to put on.
