Marty got these USB slippers about a year ago and now depends on them to keep her feet warm when she’s working at her computer.

They come with only one heat setting, but it’s not too hot and just perfectly takes the chill off the tootsies.

Marty, whose feet are usually cold, tried several different species of space heaters, but found it annoying to heat up the space around her legs when it was just her tootsies that needed the heat.

These slippers, which are safer than a space heater and cost much less, did the trick.

The only drawback is the length of the USB cable. The manufacturers could have been a bit more generous in supplying a longer cable to reach the USB port in the back of Marty’s computer. She tried plugging the cable into an open USB port on her keyboard but it sucked too much power and the computer kept shutting down that port and, therefore, the slippers.
