Who likes cold feet right? With winter just round the corner for us in the northern hemisphere, many of us will need to prepare for the icy mornings and most probably, the snow. It’s easy to keep your body warm by just adding layers but keeping your feet warm isn’t as easy. Thankfully with the use of basic tech you can now get insoles which heat your feet. These neat insoles just slip into your shoe and then are operated by a small remote. Everything is in the insoles themselves, no external battery packs and no wires. They are rechargeable of course so you can easily get thousands of hours of use.
