Footwear retailer Payless ShoeSource has introduced a new service to help ensure kids' shoes fit properly and keep pace with the rapid growth of children's feet. The service, called Growing Smart, "allows parents to bring their children into any of the nearly 4,500 Payless stores across the United States for a fitting and to receive a Growing Smart fitting chart so they can easily track their child's shoe size," says John Haugh, chief marketing officer and senior vice president of business development for Payless ShoeSource. Growing Smart is part of the footwear retailer's industry-recognised Children's Footwear Program.
