Abstract
Abstract Terry loops provide a cushion throughout at least the sole portion of the foot of the sock and ventilator panels extend along opposite sides of the sole. The ventilator panels are formed with an open mesh stitch construction to permit the passage of air therethrough and to provide for ventilation of the foot when the sock is worn. Terry loops may also provide a cushion in the instep portion and the ventilator panels may be formed with tuck stitches interspersed with plain stitches.
