I just tossed these shoes - that says a lot since I'm cheap as hell! These flip-flops are deceptively comfortable. Once I first tried them on, I fell in love. They provide a nice cushy sole and I like the way it wraps around the feet, allowing for a more secure fit. However, once you've worn them enough and the straps loosen, it does two things: 1) the foot bed slides ever so slightly while 2) the strap on top pulls the shoe back in place. This means that when you step, it will rub into the upper sole of your foot. At first, it wasn't obvious why the sole of my feet were so cut-up (!) - the slippers don't feel noticeably loose enough to pinpoint the cause. Until today, when I decided to wear them again after not wearing them for weeks. I did some very light walking and OMG, my poor feet! Luckily they didn't cost so much, but still. I'm curious to know how many 5-star ratings will remain if everyone did a follow-up review.
