Toddler University Inc. is the name of a shoe company that makes children’s footwear. The company grew from almost nothing to sales exceeding $25 million. The secret of Toddler University’s success, according to some industry observers, is a unique product design that can drastically reduce retailers’ inventory requirements. In regular children’s shoes, there are 11 sizes and 5 widths—so, to have a complete selection, retailers would have to stock 55 pairs of shoes for each particular model. But Toddler University has patented a shoe that allows the use of a one-width shoe with five shoe inserts of varying widths, thus drastically reducing the retailer’s inventory requirements.
