I wear a size 9 1/2 shoe and the size 9 1/2 in this sandle fit my foot perfectly.  It is very well made with quality materials and is very light on your foot.  The woven portion that surrounds the foot is very snug and makes putting the sandle on difficult and as you walk the elastic tightening strings cut into the toop of your arch.  It may loosen after awhile but I elected to return these.
