Grant E One's BiBi GRANT Attivo High Socks Size: S Color: Black Made in Japan Unisex - Quantity: 4-pair set Authentic product purchased from the official website. These socks use a graduated compression design that gradually decreases pressure from the ankle, promoting blood circulation, alleviating leg swelling and fatigue, and providing firm support to tighten the legs. They also use a special material called Koushi-shi fiber, which allows for comfortable wear even when sweating in the summer and provides pleasant warmth in the winter, regulating body temperature for health care. Recommended for those who suffer from cold feet or leg swelling. I would be happy if you purchase them!
