Footwork Arrows was a British Formula One motor racing team which competed from 1991 to 1996. Japanese businessman Wataru Ohashi, who was the president of Footwork Express Co., Ltd., a Japanese logistics company, began investing heavily in the Arrows team in 1990, the deal including requiring the cars to display the Footwork logo prominently. The team was officially renamed Footwork in 1991, and secured a deal to race with Porsche engines. Results were poorer than expected, and after just six races, Footwork dropped the Porsche engines and continued with Hart-built Ford engines.
