Kouichi Miyazawa runs a small, but longstanding company which makes tabi (traditional Japanese socks). He is the CEO of the fourth generation company with about 20 employees. Due to a decrease of demand for tabi, the company is struggling to keep afloat. Kouichi thinks about launching a new product line: running shoes. For the company's survival, Koichi begins to develop running shoes using their accumulated knowledge for making tabi.
