USB heated slippers are less stupid than ever now that Thanko has gone cordless. That's right, users no longer have to deal with a cord stretching between their feet and the computer.
Instead, the slippers are plugged into a USB port to charge the built-in lithium battery (an LED indicator alerts you to the amount of remaining battery power). When the cord is removed, a switch on the slipper allows the user to adjust between low and high heat. There is even a temperature dial to make fine adjustments. All-in-all, a full charge should net you around 2 hours of toasty feet. Available for $US42. [Thanko via Coolest Gadgets]
