Abstract: The present athletic sock is particularly suitable for jogging and running and is provided with terry loop shock absorber cushions in the heel and ball areas to form a relatively great terry loop density for protecting and cushioning the heel and ball areas of the foot of the wearer. Relatively lesser terry loop density is provided in the arch area to reduce the shock normally imparted to the arch of the foot of the wearer so that normal articulation of the bones in the foot takes place when the wearer is jogging and running. The shock absorber cushions are formed by providing a greater density of terry loops in the heel and ball areas of the sock than in the arch area to enhance the cushioning provided in the ball and heel areas.
