The kids' shoe brand "Ifumi," which promotes the concept of "shoes that nurture children's feet healthily." The various functions and designs unique to "Ifumi," such as mechanisms that assist foot movement and structures that allow foot muscles to exert strength easily, are the results of ongoing research and development in collaboration with Waseda University's Graduate School of Sports Science. "Ifumi" carefully observes children's feet, their movements, and their daily lives, thoughtfully creating children's shoes equipped with features for ease of wear, comfort, and safety, health, and security.
