Well I'm not using it yet.  It's going to be a last minute thing for me to use this.  They are too loose and also, it feels like there is no heel to it.  It's too flat on the ground.  If i were to wear it like this I'd be flip flopping around.  I guess I'll put it in the dryer for a bit to shrink the straps a bit.  I had another type previously which was way to loose for me, but I left it in the sun and guess what, it shrunk quite a bit.  But it fits real snug now.
