In 1933, canvas footwear pioneer BF Goodrich patented the Posture Foundation insole, an innovation in comfort and performance, and began adding the new technology to its action shoes. Goodrich shoes with Posture Foundation became known simply as "P-F" in 1937. Fashion trends in the Forties and Fifties saw PF Flyers escaping gyms and ball fields to become fashionable active footwear for everyone.
