Bincho-tan Home Socks Ankle Long Sizes Available: ・22.5cm - 25.0cm Materials: ・Outer: Acrylic, Cotton, Nylon, Rayon, Others ・Inner: Acrylic, Nylon, Wool, Synthetic Fiber (Acrylate-based), Others Made in Japan ・Pink & Navy These extra-thick home socks keep your feet warm and cozy, perfect for relaxing at home, covering your ankles. The key feature is the double-layered knit construction. This creates an air layer, making it easier to retain warmth. "Toyobo Co., Ltd." yarn is used in three inner areas (toe, heel, and calf). Bincho-tan fiber is used throughout the outer layer. Non-slip grips are attached to the bottom in two places (toe and heel). The shape makes them easy to put on. The pile knit construction provides a gentle fit, leaving fewer marks. These are carefully made in Japan by a sock manufacturer with over 100 years of history. They will be opened and folded flat for shipping. #Non-slip #ColdProtection #ColdFeetSolution #HomeSocks #Women's #Socks
