Flip Flops

My oldest daughter is 100% girl.  Picky already about her clothes and shoes.  Last summer she received a pair of purple flip flops that had little butterflies on the top.  She loves them.  Loves loves loves them and refuses to wear any other shoe.  Here is the problem.  Summer just started and her little toes are starting to stick out the end.  Normally flip flops for little people have a strap around the back but these did not and Kenna will NOT consider wearing any that do.  Do you think I can find any backless flip flops for an almost 3 year old anywhere????  Of course not.  Between her insistence on wearing these shoes and her strong opinions on what she wears every day...it's going to be a long summer.
