I had high hopes for this wedge flip flop.  It had hundreds of positive reviews, simple and cute design, fabric between the toes (instead of rubber/ plastic), and appeared to have good traction on the bottom.  I broke it in for a few days and seemed fine.  I wore it to Disneyland and could barely walk the next day.  My knees and shins were sore.  The wedge has a too-thin cushion on top of a rock-hard wedge with no give/ springy-ness.  I'm continuing to look for wedge flip flops that I can wear all day with my young kids.
