Elastomeric yarn is incorporated in regularly repeated certain courses throughout the leg and foot portion of the sock. The certain courses in which the elastomeric yarn is incorporated in the foot portion are closer together than the certain courses in which the elastomeric yarn is incorporated in the leg portion so that the density of elastomeric yarn is greater in the foot portion than the density of the elastomeric yarn in the leg portion. The greater density of elastomeric yarn in the foot portion provides a snug fit, provides greater compressive support in the foot portion than in the leg portion, and aids in the stimulation of blood flow from the foot and up the leg of the wearer.
In a hosiery article including integral leg and foot portions knit throughout of successive courses of body yarn, the combination therewith of elastomeric yarn incorporated in regularly repeated courses throughout said leg portion, and elastomeric yarn incorporated in regularly repeated courses throughout said foot portion, the density of the elastomeric yarn being greater in said foot portion than the density of the elastomeric yarn in said leg portion, the greater density of the elastomeric yarn in said foot portion providing a snug fit in said foot portion, greater compressive support in said foot portion, and aiding in the stimulation of blood flow from the foot and up the leg of the wearer.
In a hosiery article including integral leg and foot portions knit throughout of successive courses of body yarn, the combination therewith of elastomeric yarn of a certain size incorporated in every other course throughout said leg portion, and the same size elastomeric yarn incorporated in every course throughout said foot portion so that a greater density of the elastomeric yarn is provided in said foot portion than the density of the elastomeric yarn in said leg portion, the greater density of the elastomeric yarn in said foot portion providing a snug fit in said foot portion, greater compressive support in said foot portion than in said leg portion, and aiding in the stimulation of blood flow from the foot and up the leg of the wearer.
