My daughter loves these. She’s5. We got the size 12.5 and they fit her well.. a little space between her toes and the tip of the shoe but just the right amount. She says they are comfortable and good for her PE class and playing outside. We got the blue and then I ordered the black cause she loved them so much. They were on a great sale too!

Truly fits wide feet!!

Size: 6 Wide Big Kid, Color: Purple/Turq

Runs true to size in length, and the wide is actually wide enough for my 10yo's duck feet!! My daughter wears a 5.5/6 so we ordered 6wide - great fit and nice colors! We love the Saucony sneakers that have the alternative closure aka velcro straps bc my girls still struggles tying laces tight!!

Pretty Good

Size: 12.5 Wide Big Kid, Color: Purple/Turq

These shoes are pretty good. The material has broken down faster than I anticipated but they have great support.
