The design of pressure from the ankle to the calf decreases gradually, which helps squeeze the blood vessels in the calves, allowing more blood and oxygen to flow to the muscles. This enables oxygen and energy substances to enter the muscles faster and helps metabolize waste and carbon dioxide more efficiently. The compression design provides strong support for calf muscles, reduces muscle tremor, and relieves fatigue, pain, and swelling, thereby improving energy production efficiency. Additionally, these high compression socks can improve varicose veins. Made of moisture-wicking, durable, and lightweight fabric, the knee-high socks remove sweat from the skin and keep feet dry quickly after long-term use. The wide cuffs are non-slip, ensuring a comfortable fit.
