So incredibly uncomfortable!  They 'bite' the sides of my feet and made my toes so sore.  I wore them for an hour and will be returning them.  The worst part about them?  It's impossible to just slip them on!  Because of the location of the strap, you must pick up the shoe and widen the strap to get your foot in.  What a pain!  The main purpose of a flip flop, for me, is being able to slip them on easily when taking the trash out, getting the newspaper, etc.  These look cool and I was excited for a different looking flip flop, but no dice.  I do not recommend these.
