It’s generally considered a given that during the winter, you’re feet are going to suffer a bit. Whether on a bike, hiking through the woods, or skiing down a mountain, toes inevitably turn blue and icy. Not even the best of wool socks can prevent this. Now, however, thanks to the European company +t and their new +Winter Heated Insoles, cold toes will soon be a thing of the past. These things look just like all other insoles out there on the market, but inside the slight build of the insert (2mm thick at its thinnest, and 6mm thick at the heel) is a concealed heating element that can be charged wirelessly and controlled via Bluetooth connection. To juice these up all you have to do is place them on the charging pod for around 3 hours, slide them into a pair of cycling shoes, ski boots, or regular rigid hiking boots and they’re guaranteed to last for up to 5 hours. With the Bluetooth connection, users can even adjust temperature as they see fit. Winter just got warmer. When these retail they’re expected to sell for around $150.
