PF Flyers

PF stands for Posture Foundation. Developed in 1933, this patented insole technology set a new standard in sneaker comfort. The insole technology was first used in BF Goodrich shoes. It involves a wedge-like insert that moves weight to the outside of the foot, evenly distributing weight, reducing leg strain. As the success of the sneakers with the Posture Foundation insole technology grew in 1937 it became the basis for the brand name, "PF Flyers."
