Okamoto Marude Kotatsu Warm Sleeping Switch Socks

It isn't out of cruelty that Japanese mothers leave their babies barefoot even during the winter: there is a popular belief in Japan that this helps build a stronger immune system and apparently there's some truth in it. But as most of those babies realize when they become adults, going to bed barefoot if the weather is cold can lead to many a sleepless night. The Okamoto Marude Kotatsu Warm Sleeping Switch Socks are a very Japanese way to deal with these nights, bringing warmth to your feet exactly where they need it!

Available in three soft colors (gray, pink, and lavender) that also add to their overall sensation of warmth and comfort, the Okamoto Marude Kotatsu Warm Sleeping Switch Socks are knit from a blend of acrylic, wool, and other fibers in a dual-layered heat-generating fabric, and cover everything between the base of the toes to a little under the knee. This way, you not only avoid sweat but also keep the temperature of your feet balanced. And they have an extra cross-shaped layer of heat-generating material on the "insomnia" acupressure point on the heel to guarantee even better and deeper sleep!
