These shoes are GREAT out of the box!  They are sooooo comfortable and very attractive-cute with skirts ,slacks, jeans or capris.
I have a bad knee and because of the shape of the sole, I finally found stylish shoes that aren't crippling. I thought I was relegated to flat shoes forever-not so!

The size was true-I wear 9.5 and they fit perfectly.
The strap has velcro so you can make small  adjustments-nothing major, but enough.
The shoes have a semi-contoured pillowy inner sole.
They don't flop against your heel while walking like some backless shoes/wedge designs.

I would recommend these shoes wholeheartedly. An additional plus is dealing with Amazon. I never have to worry.
