As others have noted, the straps on these sandals are very, very loose and will flap around as you walk.  If they fit tighter across the foot they would be great sandals.  I thought they might be okay so kept them but sure wish I had returned and bought another pair of Tevas (which these were going to replace).  I wear a size 12 -- they fit fine in length and width so not sure why they make the straps so long.  If I weighed 500 lbs the things would still be too loose!
