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.

These boys, as i affectionately call them, are adorable. I have to wait til April but wanna start wearing them now. Couldnt ask for better. I am eternally grateful for the help Saucony gives me. I wouldn't be alive without my workouts and they know it. Thank you and I bless you. ❤️❤️❤️🕊️🕊️🕊️

Nice shoes, good price.
Size: 4 Big Kid, Color: Mint/Purple
I ended up sending these direct to my kid at sleepaway camp and thankfully they fit well and have stood up well despite her rugged use of them. Most impt to me, they have RUBBER soles, not that cheap styrafoam mascarading as a sneaker sole.
