The Kairo Heated Socks are created by Tokyo's favorite gadget store, Thanko. Each sock comes with its own mini rechargeable battery that can be discreetly clipped and tucked neatly into the top of the sock. This then powers the "kairo" heater-integrated socks that will keep your feet nice and cozy during the winter. These batteries can be recharged (AC adapter included) and a full charge is good for around 4 hours, meaning these socks will surely be a must-have accessory for working shifts in a chilly office or even a hike in the cold outdoors.
