These are outstanding. I purchased for vacation and walked around all day...comfortable!  The top strap has a bit of velcro so you can adjust for comfortable.  The sole is cork, perfect arch for me, not so high/low.  Very supporting.  The look is amaging, so boho, elegant and fresh.  These are easy to wear, very stable to walk in....you forget you have them on. I got soooo many compliments on the look. I paired with a long jersey knit skirt...I was super comfortable and looked great.
