the most wonderful thing about Rainbow sandal be that they form to you foot and hold up to abuse . they hurt sooo bad the first time or two you wear they but once they form to you foot and get break in - oh my - it be like slip on you favorite slipper . they be so soft and velvety ! despite the sterotype that come with live in Charleston , sc which go hand in hand with wear Rainbows - I eventually break down and buy they after other brand kept wear down - we wear flip flop 12 month of the year here . I have be so impressed . my husband blow through flip flop in a day - wear they in the ocean , leave they out in the rain ... he get 2 pair of Rainbows for Christmas - this will be the ultimate test - I really hope to be able to return one pair !!
