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!!
