In 1933, canvas footwear pioneer BF Goodrich patented the Posture Foundation insole. The 40's & 50's saw PF Flyers escaping gyms and ball fields to become fashionable active footwear for everyone. By the 1960s, PF was one of the most popular shoes in America. Today, PF Flyers action shoes have returned, with the original synergy of good looks and active comfort stronger than ever.
