Compression socks and stockings are invaluable companions in our daily lives, whether it's during exercise or travel. However, wearing compression socks all day often results in sweat and dust accumulation. It is advisable to change your compression socks daily and wash them regularly to maintain hygiene. Proper cleaning techniques can significantly prolong their lifespan.

Graduated compression socks are made with high-quality knitting machines and elastic yarns like nylon, cotton, and merino wool. Their scientifically designed pressure gradually decreases from ankle to thigh, improving blood flow and helping prevent swelling, varicose veins, and DVT.

Medical compression stockings, also known as compression hosiery or pressure stockings, have a long history dating back to ancient civilizations. The Greeks and Romans used primitive versions of compression bandages to treat leg ailments. In the early 20th century, modern compression stockings were developed, primarily for the treatment of venous diseases.
