Ezy Sock Donner - Double For compression or regular stockings and pantyhose. Made of steel with smooth plastic coatings. The double model helps with putting on knee-highs or compression stockings without bending or stretching. Socks or stockings are stretched over the columns and toes are inserted. The continued upward motion pulls the knee-high all the way on and pulls the pantyhose up to the knees for final positioning.
