I'm a 12, ordered a 13, and as a shoemaker, I can tell you they are a size 10 at best. I cannot get my feet into them.<br /><br />I am going to try heating them slightly in the oven and see if I can stretch them a little by wearing them when they are heated.<br /><br />I will echo the comments of many, they are waaay undersized.<br /><br />Added:  Here is a picture or my son's size 11 Crocs sandals next to my size &#34;13&#34; Sandal. I'm pretty sure it's closer to a 9 than a 13.
