Love the elastic straps.  Allows for feet to swell during summer or on flights without discomfort.  Fit is slightly large.  I normally wear size 8.5 and thats what I ordered but a little loose where back if sandals slips/rubs a little.  Ordered similar sandal from dream pairs with higher ankle strap in a size 8 and that was perfect without the slipping or rubbing.  I suggest sizing down one half size
