I was initially pleased with these sandals.  They were comfortable and the bumps on the foot bed kinda massaged my feet when I walked.  I have had them for just under 3 weeks wearing them only on the weekends or sometimes after work and yesterday the left one kept flipping off of my foot.  After looking at it, the strap that goes between your toes has torn back a bit which makes the entire strap too loose to stay on your foot.  You gotta be kidding me!  These are getting returned.
