In a word, yes. But… there are a few things to keep in mind.
You can use insulated insoles, of course, but in extreme weather or for extended periods of time, heated insoles will do much better. They’ve been tested over and over again in many different situations and have been proven to work in the coldest weather.
If you have poor circulation in your legs and feet, keeping them warm is important. If you can, choose insoles that do not have wires. Even if you cannot feel the wires now, after walking on the insoles for awhile, they may become more prominent and may hurt your feet, but they will keep your feet warm while you sit.
If you want to try heated insoles for hunting, skiing, working out of doors or riding a motorcycle or bicycle, that level of comfort may be less critical. You won’t have to pay a lot for a pair of good quality heated insoles, but don’t settle for the cheapest you can find, either. A day’s hike or ride from home in below zero weather is no time to find out that they’re not working. You could easily have frostbitten toes without heated insoles.
They work by electrical resistance; that is, by using electricity from batteries to warm up because it runs into resistance. This is transferred to the insole material and then to your feet.
There are several designs available so if you have a choice, choose a design that uses rechargeable batteries. You will go through a lot of batteries because you will need to use the insoles steadily over a period of time, although the life of a battery is affected by the surrounding temperature. Rechargeable batteries will be less expensive in the long run and can be more convenient because you’ll have them on hand all the time.
The size of the heated insoles should be taken into consideration. A thick insole will give your feet less room in your boots or shoes, so plan on either looking for thin insoles or wearing looser fitting footwear. Your feet will not feel warm regardless of the insoles if your boots fit too tightly.
