I initially purchased these in a size EU 23 (US 7) for my 23 month-old daughter to wear over the summer at the pool/beach. She's just at that stage where her feet are getting too long for size 6.5 shoes, so I thought these size 7's would be perfect. However, they turned out to be HUGE on her! She has long, slim feet, so Pedipeds usually fit her much better than many other brands of toddler shoes that are made for little-ones with chubbier feet. But not so with these Pediped Minnie Sandals. The size 7's (EU 23) were so much longer than her size EU 22 (US 6-6.5) Pediped shoes that her feet were swimming around in them (pardon the pun), and she kept tripping over them. I ended up getting the Minnie Sandals in a size 22 instead, and while they fit her for now, her toes are right up against the front of the shoe, so she won't get a lot of wear out of the smaller size, either. There will be a period of at least a couple of months where my daughter's feet are too long for the size 22's but too small for the size 23 sandals. This awkward sizing is such a shame, because these are otherwise awesome water sandals ... comfy, quick-drying, and good for developing young feet (accepted by the American Podiatric Association). The velcro strap makes them easy to get on and off, and the rubber bumper at the front of the shoes helps keep tender toes from getting stubbed. But for a shoe that costs upwards of $40, you'd think Pediped could come up with better fitting sizes.Grade: B+
