Size: S Foot fatigue, coldness, and swelling are often caused by poor blood circulation, and swelling also makes legs appear thicker. This product's graduated compression design from the calf to the ankle promotes blood circulation, relieves foot fatigue and swelling, and tightens the leg line for a slimmer appearance. Furthermore, the Photonic® fiber provides a warm wearing experience, protecting against cold. Recommended for those who stand for long periods, overuse their legs, or tend to experience swelling.
