In cooperation with leading vascular specialists, JOBST engineers developed the JOBST Gradient Compression Seamless Anti-Embolism Elastic Stocking, specifically designed to combat thromboembolism. The JOBST Anti-Embolism Elastic Stocking does this by using gradient compression, pressure gradually lessening up the length of the leg. Gradient compression helps improve the ability of the veins to move blood back toward the heart. Accurate gradient compression therapy minimizes the risk of DVT (blood clots) Soft, breathable fabric is lightweight and comfortable Latex free formula helps avoid allergic reactions Reinforced heel makes stocking more durable
