Waaaay too small. My daughter (4 years old) is currently wearing her soccer shoes from last summer. They are a size 8 in a different brand and are just starting to get too tight. I was planning to order her a size 9 of this cleat for this Spring, but read the size reviews and ordered her a 9.5. They arrived today, and I knew that they were way too small as soon as I opened the box. I actually did a double check on the box and the inside of the shoe to make sure that I wasn't sent the wrong size (nope, both said 9.5). I then pulled out her current cleats (pink bottom) and compared the two- the new 9.5s were actually smaller than her current size 8s. I'm returning these and I'm going to try a size 11 instead because I liked the quality. We will see how it goes. *For reference,  she wears an 8.5/9 in Stride Rite *
