These shoes are really comfortable but they "fart" when I walk on them.  They squish air out somewhere under the arch of my foot and are really annoying.  I love how they fit.  They are adjustable, which ensures a good fit, even if your feet are hot and swollen. I'm so disappointed that I have to send them back but I can't stand the feel of this air puffing out underfoot, or the sound that it makes.  It's unbearable, and I am not a picky person.  I have tried wearing them around the house several times, but they just drive me crazy.
