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.
