The shoes run very small, I ordered a size larger. They fit perfect except for the laces at the top. These shoes have a design flaw, the shoe's border on top hits the highest and most sensitive part of the foot, every time your foot bends you feel it dig in there. 3/4" higher or lower this wouldn't be a problem. Further the cut of the border doesn't follow the foots natural curve causing a really snug fit. The laces add extra digging points where they weave in and out. Plus the tight fit makes it difficult to put the shoe on. All of these combine to cut off circulation, creating a sensation on the foot comparable to having a tight rubber band around your wrist! I have low body weight and tiny feet, and they still do this. I would suggest waiting for the redesign on these before purchasing or by two sizes too big! If my baby hadn't pulled off the tag when I was trying these on I would have returned them. Also these are not as soft and squishy as the regular crocs. I'm giving them two stars for trying.
