Jogging and running athletic sock

An athletic sock including ball, arch and heel terry areas and being particularly suitable for jogging and running by providing a greater amount of cushioning to the ball and heel than to the arch of the foot of the wearer, said sock being characterized by having a terry loop density in said arch area which is relatively less than the terry loop density in said ball and heel areas, said sock being knit throughout of body yarn, a first terry yarn knit with said body yarn and forming a first set of terry loops in said ball, arch and heel areas, and a second terry yarn knit with said body yarn and said first terry yarn in said ball and heel areas and forming a second set of terry loops in said ball and heel areas, whereby said first and second sets of terry loops in said ball and heel areas form respective shock absorber cushions of greater terry loop density in said ball and heel areas than the terry loop density in said arch area for enhancing the cushioning provided in said ball and heel areas by absorbing and distributing shock on the ball and heel of the foot of the wearer and thereby reducing 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 jogging and running.
