These look cool (well hot), heated insoles, instant heat for your feet.
I was even more intrigued when I saw them control heat settings with a miniature wireless remote worn around their neck! Here’s how it works.
A wafer-thin, flexible, insole-heating element slips into each boot, connected with a flat wire to a removable battery pack outside your boots. Just a single touch of the ‘+’ button on the remote starts the heat. Instantly, a flood of soothing warmth surges to your feet. So you can toast your toes, or choose sustained moderate heat depending on the wind chill that day.
You can get the Thermic Sole from the Herrington catalog for $350, which is way out of my price range so I’ll be sticking to woollier socks.
