I have owned my pair for almost a year, now, and they are as good as the day I bought them even after wearing every day (Even in the unexpected rain--not recommended with a flip-flop but still comfy)!  They're dirty, of course, but not much wear and tear at all.
I didn't buy mine on Amazon and paid more in-store, but recently bought my best friend a pair from this seller and have nothing but good things to say about them!
We had to return hers twice because the size was too small, but the seller was very helpful and sent the larger pairs out quickly.  Now she has the right size and is loving them as much as me!
I usually cook barefoot, but my feet will start to hurt after a while standing.  I will put these on to finish cooking because they are so comfortable and they help my feet and lower back.  I wish I had these when I was pregnant!  I can stand and walk in them all day with no foot pain and the suede thong doesn't rub between my toes or on top of my foot the way some of the rubber or plastic kinds will.  There's no irritation!
Admittedly, the little bumps all over the foot feel weird and take some getting used to, but I don't even notice them, now.
I highly recommend these, especially if your feet start to hurt after standing or walking for long periods of time.
Sizing is weird: My pair is a smaller size than I typically wear; however, my friends is a larger size than she typically wears.  If possible try on in-store before buying online or review sizing information or charts to find a good fit!
