The soles are too big and the bands are too tight. I'm trying to fix my alignment and read about the importance of being barefoot.  These looked so nice in comparison to the rest on the market, so I was really excited.  I was going to exchange for a smaller size but then the bands would probably be even tighter.  I suspect they might even be why the sole looks too big.  When I shove my foot to the top of the sole it looks right, but the tightness of the bands make it slide back as soon as I start walking.
