I love my rainbow flip flops and wanted a comfortable show in times when flip flops are not acceptable. I decided to order these, I usually wear a size 11.5-12 but based on other reviews I ordered a 11. I'm glad I did because they fit like a glove. Like other rainbows they are a little tight in places and the sole is a nice touch but I expect it to act like a rainbow and become my most comfortable pair of shoes in about a month. If that happens I'll have to upgrade but until then I'm happy with the quality of these shoes.
