Laces coming off
Size: 5 Big Kid, Color: Blue/Turquoise/Pink, Size: 5 Big Kid, Color: Blue/Turquoise/Pink
Cute and comfy but the laces are coming apart after two weeks of just wearing them to school and home. We got a measly 10$ refund for our troubles 😑

Are holding up great, but needed the wide
I bought these shoes for my daughter to wear to kindergarten. They wear navy uniforms and she loves pink so I thought these were perfect. I ordered her size according to the size chart (but didn’t check width because she’s never needed wide shoes in the past). The normal width were too tight on her toes but the length was right. I returned them for the wide and they are perfect. 2 months into school they still look brand new. Just be sure to check both length and width. I printed a measuring guide from Saucony’s website.

Nice, Tough & Comfortable!
Size: 6.5 Wide Big Kid, Color: Black
Bought as an everyday school shoe for my 10 year old son. He likes them a lot and is holding up great through rough boy play, and they still look good after a couple months now.

Pink and purple perfection
Size: 13 Little Kid, Color: Pink/Purple, Size: 13 Little Kid, Color: Pink/Purple
Fits great and perfect colors for my (not so) little. This is her first pair of "tie" shoes so we're still learning, but the laces are a good length for teaching and practicing. She says they're very comfortable too.
