Your feet are one of the major sources of body heat – lose heat through your feet and you will feel cold all the way through. Even wearing thick boots for winter, your feet and toes can be below the optimal temperature if you work outside, and you can feel uncomfortable or even hurt yourself if you do not take extra precautions. Heated insoles for cold weather can be an ideal solution to this. Regardless of whether you spend your time outside for recreation, going for long walks in the crisp air or even work long hours outdoors, some insoles with built-in heat generation can go a long way towards keeping your feet warm.
There are two basic types of insoles; battery powered and chemical. The battery powered ones can last about 8 hours, usually; the chemical versions a little less, maybe 6 hours. Thankfully it is scarcely possible to tell that you are wearing either kind, other than the temperature improvement of course, as they feel just like regular insoles. In fact, they essentially are just regular insoles, only with a heating element added, so they do not affect your walking at all.
Heated insoles for cold weather are a really great invention, very versatile, and can be used by anyone – men, women and children. There are no safety issues to be aware of. Most of the battery operated wireless heated insoles will include a temperature sensor that prevents it getting too hot, so there is no risk of burning or fire. The best rechargeable batteries are of the lithium-ion variety, so look for these when you are buying heated insoles for cold weather – even though they might cost a little more, they are well worth it for their effectiveness and reliability. These insoles can be found easily in many major supermarkets and shoe stores.
