Great shoes
Size: 8 Toddler, Color: Camouflage Gray
Bought these for my three-year-old son, they fit great and they are easy for him to slide on himself. The laces seem to come untied a lot, but otherwise we love them!

Perfect for Active Kids
Size: 4 Big Kid, Color: Black, Size: 4 Big Kid, Color: Black
My son loves these shoes. He says they’re really comfortable and lightweight, and he can run and play in them easily. So far they’ve held up well. He can fit them. Non Velcro and slip resistant.

Good, but not great! Insert kept falling out.
Size: 3 Big Kid, Color: Black
I bought these for my 8 year old and the insert was loose and had to be played with multiple times before I could get it to stay in place. I eventually had to place a double sided sticky pad to get the insert to stay.
