Cute and practical
Got these for my 8 year old for the school year. They fit as expected with good traction on the bottom. She's had them about a month and they are still holding up well. She loves them because they look cute and I love them because they keep her supported all day long!

Great tennis shoes!!
Size: 4.5 Big Kid, Color: Black/Orange
The best shoes my son had this past year. He loves them and has worn them continuously, not only for running and training, but also for daily use. He really likes them and says they are very comfortable.

Size up
Size: 2 Big Kid, Color: Black/Pink
My daughter loves them. However they run a size small so we had to size up. She is anywhere from a 13-1 and we had to get a 2 in these. Overall great show and quality. She also just learned how to tie her shoe (7yo) and they are easy for her to tie. Style is great for running and sports too. Overall great value for the money.
