Truform 8865 part of the "Classic Medical" series for men and women use 20-30 mmHg compression technology to restore leg health. The amount of compression is expressed as mmHg (millimeters of mercury). These medical-grade support stockings have five intervals of graduated compression, which is greatest at the ankle, then gradually decreases up the leg. Doctor-recommended to help relieve tired, heavy, and aching legs, graduated compression provides two primary benefits: increased pressure on tissues beneath the skin helps reduce swelling, and the compression action helps control the size (diameter) of superficial veins. This combination prevents the slowing of blood flow and blood pooling in the extremities. Truform medical hosiery is ideal when sitting or standing for long periods of time. The therapeutic support helps in the treatment of spider veins, varicose veins, and swelling of the leg and feet. Designed with a gender neutral smooth knit, the traditional styling is made to perform with daily use. Opaque material conceals blemishes while promoting recovery and revitalizing the legs. Features include: closed-toe, knee high fit, and medical grade completely latex-free materials. Use corresponding size chart.
