Abstract: A sock and method for manufacturing the same utilizes a formable or "puff" ink. The ink is applied by screen printing to the upper heel area of the sock and the ink is heat set. The ink rises upon setting (curing) to form a friction producing surface on the back of the sock above the heel. The printed surface prevents to sock from sliding into the shoe during periods of exercising such as walking, jogging or other physical activities.

Abstract: A decorative surface for the exposed welt of a footlet-type sock is formed by knitting a plurality of successive courses of an elastic yarn and a synthetic or natural yarn in plated relationship. Each of the courses includes stitches formed and cast off in selected wales thereof separated by at least two successive float stitches, whereby the combination of the elastic yarn and the aforementioned knitting technique cause relatively wide bands or walewise ribs of raised or high relief fabric separated by relatively narrow bands of base fabric which exhibits a low relief area.

Abstract: The exposed welt of a footlet-type sock is divided by knit construction into a rear portion and a front portion. The rear portion, which is substantially the rear half, is of a substantially freely and outwardly rolled construction. The rolled rear portion is not tacked down and encircles the lower ankle area when emplaced on the foot. The remainder or front portion includes an upper edge which is tacked down in a controlled folded construction. The rear portion is thus left free to roll upon itself into a relatively heavy, thick mass of material. The front portion, on the other hand is folded across the instep of the wearer minimizing the thickness of material beneath the shoe tongue. The rear half is a knitted fabric formed with a combination of body yarn and elastic yarn. The elastic yarn forms the backing fabric for the body yarn, which itself is formed into terry loops.
