I love the foot bed/arch support on these flip flops, but something about band part just hits my feet in the wrong way and is so painful they're unwearable.  I wore them around the house for a few hours and they were five, but wearing them shopping for a few hours literally made the top of my feet hurt so bad I couldn't wear any shoes for a day afterwards.  Which is heart breaking, because not only can I not return them-but the BOTTOM of my feet adored them! :-(
