Ordered the little kids 9-10 for our son, and the length was right (he's around a size 9) but he couldn't actually fit his foot all the way in because the straps were so thick. He is of average size and weight, but he does have wide feet, so probably a kid with narrower feet would've been fine.<br /><br />As a side note, I originally ordered the 'slim' version of these (which I think is the 'girl' version, based on the color options) in the same size, and though he didn't like the color, they actually fit his feet! The strap was slightly slimmer, and so he had a bit more room to slide his foot in.
