Slip a pair of Digitsoles in your shoes to track your steps, heat your feet

Know someone with cold feet? New insoles from the Nancy, France-based company Digitsole may be just the solution. Digitsoles fit in most shoes and boots, but they are no ordinary insoles. These come with onboard USB, Bluetooth 4.0 and a smartphone app that allows users to adjust the temperature of the footbeds all the way up to a toasty 104 degrees.

In addition to bringing warmth to frosty toes, they also feature a built-in step tracker than can log steps taken, calories burned, and distance traveled. This means there is no need for a fitness tracker on the wrist or in a pocket. All the counting goes down below the feet and inside the shoe. Digitsole says this gives their device a more accurate accounting of steps taken. And it makes sense, but we’re thinking more about all those times we’ve been stuck on a ski lift in the middle of a storm with our frozen feet dangling in the air, and how nice it would have been to whip out our phone and turn up the heat on our icy toes.

The Digitsoles, which are a half inch thick at the heel and less than a quarter inch (5mm) at the toe, weigh 3.5 ounces and are powered by a high-capacity rechargeable battery that will reportedly keep the insoles running for up to 8 hours.

Sadly, the Digitsoles are not yet on the market. Company founder Karim Oumnia is currently raising funds on Kickstarter and have already bypassed the goal of $40,000 by raising $53,171. If all goes well, backers of the Kickstarter project will get their Digitsoles in January of 2015.
