I bought these boots for my daughter a size above his normal size so that it keeps them longer. Result it when I lose the door, so to see the product size slightly larger. She loves to jump in puddles with. It is an indispensable accessory to have in its range by rainy weather. Plus: the inner coating that glides foot in the boot of background. The feet breathe better. One regret: the lack of choice in colors (Navy Blue, Red and Yellow).
