The Growing Feet app uses a translation of inches and cms to find a childs corresponding shoe size. This informs the customer of what size to buy, without the child being present. Our sizing utilizes a general correct fit (allowing for proper use of the desired product). Sizes entered can be saved, allowing data storage for multiple children, as well as a projection of growth on an average scale of time. North American, European, and UK sizes available. Growing Feet aides in the development of your child, and gives him or her the overall benefits of having the product fit properly.
