My little one is in between sizes 8.5-9.  I ordered a size 9 and they fit nicely with room to grow. Note, my little one has wide chunky feet and usually in other brands like Stride Rite I have to order her shoes XW. These fit her nicely.  If your child has narrow feet these may be a little too wide.<br /><br />I wouldn't use these for playing in the park as they dirty easily and the rubber seems to wear rather quickly.
