Abstract
A circular knit therapeutic stocking in which bare elastomeric yarn is knit in selected courses and wales with a non-elastomeric yarn in other selected courses and wales in the welt, boot and foot portions of a stocking to provide a retractive or compressive force of graduating degrees as required with a circumferential heel-instep band of lesser retractive or compressive force, and a closed toe area in which stretchable fabric with minimal retractive forces is integrally knit to the foot portion of the stocking whereby the bare elastomeric yarns are buried or concealed by the knitted non-elastomeric yarns and in which a welt panel of flexible and relatively non-stretchable material is secured in the welt portion of the stocking to be positioned on the inner upper thigh of the leg of a wearer. The inner surface of the welt panel being lined with polyurethane foam or similar material which would have a high coefficient of friction against the skin in order to help maintain the stocking in position on the leg of a wearer.
