I bought these as a gift for my sisters birthday. They started coming apart a little after a month of her wearing them. She has not abused them at all. I tried to contact the seller but never heard anything back. I have a pair of Rainbows as do most of my friends and my partner. I have no problem with mine and neither does my partner or friends. matter of fact, my partner has been wearing the same pair since 2002 and they still are not torn in any way. I don't know what to do to resolve the issue I have with this seller. All I want is a replacement pair for my sister. How embarrassing  it is for a pair of Rainbows given as a birthday gift to come apart in a month and the seller avoid you! I do NOT have a problem with Rainbow, I will never wear any other kind of flip flops. I have a problem with the seller and the lack of their customer service/customer satisfaction.
