Bought a pair for my daughter.  She said they were soooo comfortable, I bought a pair for myself.  She was right!!!  These are the most comfortable flip-flops!!!  I did buy a size larger than what I usually wear, a size 10W instead of a size 9W.  The 9W fits, but it is a little snug across the top.  The size 10 is much looser.

I highly recommend these flip-flops!  They are great!!!!
