I really wanted to love these shoes and I wore them around my house for several hours over a couple of days to make sure they were okay.  The first time I wear them out on a day trip and the inside of the straps rubbed so much against the top of my feet that they are currently scabbed up.  They fit true to size and the arch support is great like my Vionic flip flops, but now I'm stuck with shoes I can't return and I'm out almost $100.  Other reviewers have complained of this, too.  Not sure why they don't remedy it with a softer inside.  I won't be wearing them again.
