＊Warm-up Socks Set of 2 Colors: Black, Gray Size: 23-25cm Brand new, unused. Retail price: 3389 yen I am selling these because I don't have a chance to use them. ・The biggest features of the warm-up socks are the "extra-thick ankle pile" and the "moisture-absorbing and heat-generating fibers" in a double-layer structure. Based on human health engineering, the thicker design around the ankles prevents cold air from entering, promotes blood circulation, and increases heat retention. Furthermore, the polyester x acrylic hybrid material has 15% higher heat retention than wool and is durable, so it is less likely to lose its shape even with daily use, providing a comfortable fit. You'll feel warm as soon as you put them on, making them perfect for outdoor activities or relaxing indoors. ・The secret to keeping your ankles warm: Concentrated design of thick pile on "Sanyinjiao" The ankle is an important part that connects the foot and leg. Keeping this area warm promotes blood circulation, warms the body, and effectively protects leg warmers. MIZIKIRIN warm-up fluffy socks adopt a thick design that fits snugly around the ankles. They cover Sanyinjiao 360°, trapping heat and significantly reducing heat loss, transmitting warmth throughout the body. ・New moisture-absorbing and heat-generating fibers with brushed lining, increased warmth We aimed for socks that you can feel warm from the moment you put them on. Compared to wool, they reduce heat loss by 15%, effectively trapping heat, and efficiently draw natural heat from foot sweat and moisture, enhancing the heat retention effect. Furthermore, the inside of the socks uses a fine fleece material, effectively preventing cold air from entering and heat loss, and providing a comfortable fit even after wearing them for a long time. Perfect for cold weather protection in autumn and winter. ・Commitment to durability and cleanliness Comfort and durability are the most important things. Warm-up socks use a hybrid material of polyester and acrylic, which boasts excellent abrasion resistance. They are less likely to lose their shape even after repeated wear, do not get holes, and also have excellent elasticity. Furthermore, the surface treatment makes it difficult for pilling to occur, and the comfortable fit is maintained even after repeated washing. Reinforcing the seams of the toe area prevents pilling.
