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.

My son destroys shoes, same thing happened here.
Size: 5 Big Kid, Color: Black
For some reason my son started doing the duck walk at school and while performing this little trick for his classmates he ripped the rubber that wraps over top the toe. Now, instead of being glued up and into place, its basically sagging down. Thankfully that's the only thing that's gone wrong with these and honestly this sort of wear and tear is not typical. What I would say is that if your child is rough on shoes, I would pass on these. They are very nice, very light weight and are great for school. However, due to the design, they might not best good for some kids.
In terms of sizing and comfort, my son wears a 5 and these fit him very well. He has wide feet like his dad, and these don't bother him at all. He's says they're very comfortable and does enjoy wearing them.
