Whether you’re a weekend enthusiast, or a professional athlete, skiing is one of the best ways to enjoy winter and the great outdoors.
Any person who has spent a long period of time outdoors knows that the fastest way to ruin your fun is cold, frozen toes.

More Features on the Hotronic Foot Warmer Ski Boot Heater
These boot warmers don’t just work in ski boots, they have also been installed in other footwear such as hiking boots. The heater can be easily transferred between different types of winter footwear.
These footwarmers come with three standard heat level settings, and with a bonus timed heat setting. This guarantees users can always choose the right amount of heat for their needs. However, different heat settings have a direct impact on the battery life.
If these ski boot heaters are used continuously at the highest setting, users can recharge the battery during a break for added time. The bonus heat setting allows for an increase in heat for 3 minutes at a time. This prevents the battery from overheating or completely draining.
An LED light indicator displays the battery strength, meaning users do not have to worry about how much battery is left. Finally, the battery is rechargeable, and will last for multiple seasons without being replaced.
2. Therm-ic rc 1600 Smart Pack – Ideal for Beginners & Professionals
The Therm-ic rc 1600 Smart Pack ski boot heaters are geared towards a wider array of skiers, and work with any Thermic Soles. Each smart pack comes with a remote control, a universal charger, and a lightweight lithium ion battery.
The battery life for this ski boot heater lasts the longest, but it is the most expensive. It is also not the greatest solution for people seeking a little bit of added warmth.
As an added benefit, the smart pack works with other Therm-ic ski boot heaters and features an anatomic 3D structure. The 3D structure is made of EVA foam for added support and cushioning in order to give users all day comfort.
The Therm-ic rc 1600 ski boot heaters are designed to satisfy even the professionals, and is great in any area, no matter how cold it gets. The battery life lasts up to 29 hours, but like other ski boot heater batteries, the more heat you use, the shorter the battery life will be.
Additional features of the Therm-ic rc 1600 Smart Pack
The remote control makes things easier, and users no longer have to bend down to adjust their heat settings. As an added perk, the battery charges quickly which allows users to recharge in between breaks. The charger included is a universal charger, allowing it to be used anywhere in the world with any outlet type.
To better improve circulation in your feet, this heater uses impulse control. By facilitating natural blood flow, and thus, natural heat, the heater works in conjunction with the user’s own body for an outstanding heat performance.
In order to use the Therm-ic rc 1600 ski boot heaters, the user must already have Thermic insoles installed in their ski boots. If they do not, many prominent sports retailers offer them in conjunction with other ski gear for an additional cost.
3. Hotronic FootWarmer S3 – Long Battery Life
The Hotronic Footwarmer S3 ski boot heaters are very similar to the S4 mentioned above, with the only difference lying in the slightly shorter battery performance. On the lowest setting, the battery provides anywhere between 17 and 18 hours of heat, and on the highest, about 2 to 4.
Similar to the Hotronic Footwarmer S4 foot warmers, this ski boot heater is available in two types: custom and universal. The custom foot warmers include 2 battery packs, 1 charger, 2 heating elements, 1 pair of self-adhesive covers and strips, and the operating instructions and a limited warranty card.
The universal variety offers all of the above components, plus a pair of cut to size, one size fits all insoles.

The battery also features an LED light to indicate how much battery life is left. The charger is a universal charger, making it an ideal choice for users anywhere in the world. This heater is extremely easy to use and switch temperatures without any hassle.
4. Therm-ic SmartPack rc 1200 With Remote – Various Heat Settings
With 3 settings, all it takes is the press of a button to receive the right amount of heat for your needs. However, like other batteries, the higher the heat setting, the shorter the battery life will be.
In order for this heater to work, your ski boots must already have ThermicSoles installed in them. This shouldn’t be an issue as many name brand ski boot retailers offer the insoles with their boots. If you don’t have these insoles, you do need to buy them separately.
This heater, like other ski boot heaters, features a remote control operation, and uses a universal charger. The remote makes it easy to change between the different heat settings.
The lithium-ion battery features 3 heat settings, and uses impulse control to facilitate natural circulation in the user for added warmth. If you often ski on difficult terrain, then this is a great choice for you.
5. Therm-ic SmartPack IC 950 – Great for Any Outdoors Experience
However, the 950 is a great choice for fair weather fans and serious athletes alike. Similar to the other Therm-ic ski boot heaters, the IC 950 also has impulse control to facilitate natural blood circulation in order to promote natural warmth in the user.
It doesn’t matter what shape your feet are, the cut so size insoles will comfortably fit every user. The lightweight battery is also great, because it doesn’t distract the user from their skis as they go about their day on the slopes.
If you’re more of a snowboarder than a skier, the 950 also works, and on the lowest setting, it offers up to 18 hours of heat. Like the other types though, the higher the heat setting, the shorter the battery life.

Choosing the Right Ski Boot Heaters
There are a number of factors to consider when looking for ski boot heaters, or for your ice fishing boots. See below for the following factors:
Consider Your Needs
The first, and maybe most important thing you need to know is your personal needs and location: where are you going to be skiing, and what kind of skiing are you doing (downhill or cross country).
The next thing to consider is what type of skier you are: are you someone who enjoys going out on fair weather days? Or are you a dedicated athlete who is prepared to ski in all types of weather conditions?
Once you know that, determine what your battery life needs are. A user who is out all day is going to have different battery life needs than someone who is only going to be out for a few hours.
While looking at the battery, a factor to consider is how many heat settings each comes with. For a fair weather skier, a battery with ultra-high heat settings is most likely not needed.
The next item to consider is the installation methods and how easy your options are to use. Finally, the last item to make note of when choosing a ski boot heater is your budget and the cost.
Consider the Worth
High performing ski boot heaters are expensive. Is it worth spending the money on ski boot heaters over other methods, such as the one time use heat packs or layering up on clothing? That’s really up to the user, but a few things to consider in making that decision include a few questions to ask yourself:
Is it worth it to keep your feet from becoming cold when out on the slopes? Does a ski boot heater give you more time to enjoy outside?
Are you someone who spends time doing other outdoor activities, and therefore, need a versatile option to keep your feet warm?
And finally, will you enjoy your time out on the slopes more than you already do, if your feet stay warm the entire time?
Ski Boot Heaters FAQ
How long do the batteries last in a ski boot heater?
The battery life of a ski boot heater is dependent on the setting. Most batteries can deliver up to 10-13 hours at the low heat setting. At the highest heat setting most ski boot warmers will last about two hours. It is good to keep in mind, that the lower the heat setting is the longer the duration will be.
Stay Warm This Winter Season With Ski Boot Heaters
When choosing the right ski boot heater for your needs, it is important to take into consideration all the factors that will impact your choice. Those factors include battery life, heat setting options, and temperatures.
Other factors include your life style- a professional athlete is going to want something different than a normal, every day user.
While there are other less expensive options out there, a ski boot heater is one of the most versatile solutions to keeping your feet warm, no matter how long you are outside.
What’s more, some choices can even be used in other winter footwear types, guaranteeing that users remain warm no matter what they are doing.
