Okamoto Kokopita Plus Warm Sensation Invisible Sneaker Length Women's Black 23-25cm, 2 Pairs The new "Kokopita Plus Warm Sensation" line is here from "Kokopita"! For those of you who have always struggled with freezing cold feet when you go out, experience "tangible warmth." This is a new item developed by Okamoto, the sock specialist. POINT ☃ The secret to "warmth" is in the "toes" A special two-layer structure is used for the toes. It absorbs sweat and moisture to generate heat, and retains that heat to keep you warm. POINT ☃ Warm even when you're outside In response to the voices saying that conventional "warm socks" were thick and bulky, making it impossible to wear shoes, we aimed for a thickness that allows you to "wear shoes." By using a micro-cushion knit that is finer than regular pile fabric, we have achieved both moderate thickness and warmth, making it the perfect item for going out. No more cold feet, no more worries. Enjoy a comfortable winter with "warm sensation." Material Composition: Acrylic, Polyester, Other
