These new insoles from +T can be controlled wirelessly through an app, they charge wirelessly, and they have a built-in accelerometer that allows them to kick on automatically when you start walking. All of this adds up to one very convenient truth: you don't have to think about them. With all the things the +Winter insoles do automatically, you don't have to constantly be fiddling with them, you can just enjoy having toasty feet.
The insoles are also water-resistant and supposedly flame-retardant, and you really want that latter if it's something touching your skin. The insoles are already out in Europe, but the company has launched a Kickstarter in hopes of getting them to the United States. You can grab a pair for $98 and say goodbye to your clammy, cold feet that leave you feeling like your toes are going to fall off.
