Cute and comfy shoes!
Size: 4 Wide Big Kid, Color: Black/White
I like my new shoes!! My dad ordered these shoes for me and I love them. They are so cute and stylish. They fit well because of their wide size so my toes have enough room. They are not to heavy so I can easily run ostead of my feet being weighted down. They are very durable because i have been using them and they don't easily rip or tear. I love these shoes.

Runs small
Size: 11 Wide Big Kid, Color: Black/White, Size: 11 Wide Big Kid, Color: Black/White
Runs extremely small, but does look like a nice shoe. I ordered 11W for my grandson. The image shows a different brand size 10 red shoe. As you can see the red one is bigger and wider than the new one ordered.

Good. Just good.
Overage at best. Not a bad sneaker for running and courts. The bottoms wore out faster than I thought but they are comfortable.
