The Hotronic FootWarmer Power Plus Custom S4+ set is the ideal heating option. It’s designed to work seamlessly with any insoles you’re already using.
What We Like
Whether you’re using the insole that came with your shoes or you have a custom-made orthotic device, this heater will keep your feet warm and toasty.
Although the product doesn’t come with insoles, it does have Cambrelle covers, which use an adhesive over the heating element to attach to your current insole to turn them into one unit.
The heating elements are two small, round pads that can be placed on your insole wherever you need them most.
They connect to 4-cell NiMH battery packs that can be placed around your ankles or waistband with the extension cables.
The new version of this small heater system features an increased battery life, lasting between 3 and 21 hours, depending on the temperature settings.
There’s a button on the battery pack to select your preferred temperature. You can choose from four different settings, and LED lights show you which setting it’s on. At its highest, the heat goes up to 170 degrees Fahrenheit.
It comes with a 100 to 240-volt charger, with adaptors for US and European plugs. They also have overcharge protection.

There’s no need to replace your current insoles with this heating system. You just attach it to your insoles and it does a great job of warming your feet with four heat settings.

2. Kamlif Memory Foam Heated Insoles
These insoles are affordable enough for almost everyone and can easily be added to any shoe. They provide nice warmth from heel to toe.
What We Like
The Kamlif Memory Foam Heated Insoles are affordable while still keeping your feet warm.
Instead of only the insole only heating a section of the insert, the entire insole from heel to toe is warmed up. This provides the optimal amount of heat for keeping your feet warm.
The insole is also made of memory foam, which offers excellent cushioning and shock absorption.
A medium to high arch support in the memory foam adds structure. And these insoles can be trimmed for a perfect fit. Anti-skid silicone underneath keeps it in place.
They are also breathable and conduct heat efficiently. This means the warmth is well-distributed across the entire insole, but it also allows your feet to breathe so you don’t get too hot.
Kamlif insoles use a titanium crystal heater system, which is unobtrusive.
The batteries are lightweight and strap around your ankles. They’re not bulky, and the battery can last for up to 6 hours on the highest temperature setting—131 degrees Fahrenheit.
Why We Like It
These insoles are comfortable, padded, and offer good warmth, all for a very affordable price.
PROS:
- Memory foam cushions your every step

Electrical elements are embedded in the rubber layer, distributing heat evenly and featuring four different temperature levels.
On the lowest setting, the battery can last for up to 5 hours, ideal for a few hours of hunting.
The battery pack will need to be attached for the insoles to work, but they come with Velcro straps that can be wrapped around the ankle. A 27-inch power cord is included, so you can also wear the battery on your belt if it’s more comfortable.
The batteries are detachable, so you can replace them when they no longer hold a charge.

The Therm-ic Insole Heat 3-D is a good choice if you need strong arch support. It may not be suitable for overpronators, but it’s excellent for neutral feet.
What We Like
The Therm-ic Insole Heat 3D insoles have a 3D anatomical design that molds to your feet, providing excellent arch support.
EVA foam material contours to the curves of your feet and helps to absorb shock every time you take a step.
The heat is centered in the forefoot, provided by heating elements built into the insole. They maintain a consistent temperature, so your feet stay warmer for longer.
You will need to buy batteries separately to use these insoles. The charging cable is thin and hardly noticeable, so it won’t get in your way when you connect it to the batteries.

PROS:
- Sturdy, supportive arch support

Whatever activities you take part in during winter—walking, shopping, or working—keeping your feet warm is essential for foot health. These insoles are ideal for using in winter boots.
What We Like
These insoles have a warm, fluffy design that looks like a comfortable winter slipper. The top cloth is made from wool, which is great for relaxing at home, but it’s ideal for wearing inside winter boots.
Bamboo charcoal material in the sole helps reduce odor and absorb sweat, so they shouldn’t get too hot even when your feet are heated.
If you use the batteries on the lowest setting, you can get about 10 hours of use. There are three different temperature settings, and an LED indicator light allows you to see your temperature setting and your battery capacity at a glance.
The battery pack is meant to be attached to your calf. However, the wire is short, and you may have to wear it on the inside ankle, which can be uncomfortable and become a tripping hazard.

Buyer’s Guide – Heated Insoles for Shoes and Boots
Heating Element
Most heated insoles have a heating element built into the materials. Sometimes it’s a full-length heating element, but sometimes it’s smaller and localized, for example, in the forefoot only.
They’re made of copper wiring or far-infrared radiation—FIR—strips. Both are safe for use.
Materials
Most heated insoles are made of a thin layer of EVA foam. Often there’s no adequate arch support for flat feet or high arches, and the thin layer only provides a small amount of cushioning.
Battery-Powered vs. Natural Heat
Battery-powered insoles are very safe and highly effective. They last for many years and provide heat for many hours at a time.
Natural heat insoles are single-use products. They’re eco-friendly, so you don’t have to worry about damaging the environment. The heat doesn’t last as long as battery-powered insoles.
Temperature
Natural heat insoles have no temperature regulation as they have no electrical elements.
However, battery-powered insoles usually have built-in temperature regulators that allow you to select a comfortable temperature for you.
They usually offer low, medium, and high settings, which can be controlled on the battery unit or even with Bluetooth.
Price
Naturally heated insoles are more affordable if you’re only going to need them for a few days.
However, if you need to warm your feet often—especially during winter—then a battery-operated one will be more cost-effective as it lasts for a long time.
Convenience & Functionality
A heated insole with a battery pack on the ankle may not be convenient for some people. For example, if you work in an environment where it may bump or get caught on hazards.
It may be better to choose a heated insole with a built-in battery pack in these cases.
Washability
Heated insoles usually don’t need to be washed. If your feet sweat, you can remove the insoles for a few hours and let them dry naturally.
You should not put an insole in the laundry if it has a battery pack inside of it.
Fit & Comfort
You may want to remove your shoes’ current insoles, as adding a heated insole might be too tight.
If you have an extra-depth shoe or a very thin heated insole, you may want to consider placing a supportive insole in your shoe along with the heated insole, as most of them don’t provide a lot of support for the foot.
FAQs
How Do Heated Insoles Work?
Heated insoles give off warmth underneath your feet, which then surrounds your feet and keeps you warm for an extended period of time.
There’s a heating element inside the insole, warmed by an electrical current. A battery provides the current, either contained in the insole—usually in the heel—or attached to your ankle in a comfortable pouch.
Are Heated Insoles Safe?
Yes, heated insoles are safe, even for extended periods of time. Most of their heating falls into 3 to 6 volts, which is enough to warm your feet up but not hot enough to burn. Many of them also include regulators.
However, naturally heated insoles may get warmer, as they have no regulator. But they should still not get hot enough to burn you.
What Are the Benefits of Heated Insoles?
Heated insoles are excellent for outdoor use in cold climates. They increase your comfort in cold weather, reduce the chances of things like chilblains and frostbite, and allow you to spend more time outdoors without the risk of the cold affecting you.
Although they include heating technology, they’re lightweight and don’t feel uncomfortable or weigh you down.
They feel just like normal insoles, although many don’t offer adequate arch support for flat feet or high arches. Most of them are also rechargeable and will last you many years.
What Are Naturally Heated Insoles?
Naturally heated insoles are insoles that don’t use a power source like a battery. They’re single-use insoles that rely on a combination of natural materials to provide heat.
The natural mixtures may include substances like activated charcoal, iron powder, salt, water, and vermiculite. When they come into contact with air, they react and give off heat.
They’re also usually eco-friendly, but you can only use them once before throwing them out as the materials can’t react to air more than once.
