Stylish and comfortable
Size: 5 Wide Big Kid, Color: Fuchsia
I got these for my 9 year old who needed new sneakers. She loves all things pink and instantly loved the look of these shoes. They are extremely breathable which is great for running around and airing out those sweaty feet. The fact that they are wide is perfect for her as well; so many sneakers end up being narrow and confining. They fit great and look great and both mom and daughter are very happy with these!

Comfortable, durable, affordable...what more could you want? Lol
These fit well and were comfortable for my son...and they lasted until he outgrew them. That's saying a lot for a 9-10 year old boy. Lol. They are a great deal for active kids.
