Best Ski Boot Heaters

There are a lot of different options on the market: from heated insoles with a rechargeable battery-powered heat component, to heated insoles without built-in batteries or even chemical heated packs that you can stick to your ski socks.

We chose to review for this article the best ski boot heaters, five solutions that really work, to help you decide which one is the right one for you. 

Check them out, and get ready for the snow!

1. ThermaCell Rechargeable Heated Insole

ThermaCell Rechargeable Heated Insole

First on our list is an elegant high-tech wireless solution from ThermaCell: a rechargeable foot warmer operated with wireless remote control.

Its high-tech technology makes this heated insole really convenient, you won’t have to deal with wires, extension cords, external batteries mounted to your ankle, or battery strap brackets or Velco straps.

You just have to make sure you charge their Lithium-ion battery packs embedded in the warmer before your ski day, set the insoles in your ski boots, use the remote to set the temperature to your liking (out of the three heat settings), and you’re good to go.

You’ll have toasty heat to warm your feet for all your ski adventures. 

The ThermaCell warmers work really well in cold temperatures, the heat source is located closer to the toes and is very noticeably warmer even on the medium setting. You won’t need the higher setting very often or for very long.

The battery lasts all day, providing you a warm and comfy ride. On a medium setting, you won’t run out of battery charge in a 7 hour ski day.  

At the end of the ski day, pulling the insoles out of very cold ski boots could be challenging. But it will be a bit easier if you let the boots get warm first.

Keep in mind when ordering ‎this heated Insole that the Thermacell inserts are very thick and can make your ski boots feel too tight.

You might need to remove the original ski boot insoles first. Because they are stiff, not soft and flexible, and can’t be trimmed on the heel part, they work best in very roomy boots. So make sure your ski boots are not too tight in the first place.

Also, if you wear the boot size of 6 1/2 – 8 (US sizing), you should consider ordering a size “small” for the warmers.

The only downside is that unfortunately, there is no feedback mechanism showing how much juice was left in the batteries, it would be useful to know how long it can last before the next charge. 

Other than that, ThermaCell foot warmers are a great product which will transform any cold day in the mountains into an amazing ski experience. 


  • Batteries: Rechargeable Lithium-ion polymer batteries 
  • Remote control: Yes
  • Battery life (as advertised by manufacturer): 2500 hours
  • Brand: ThermaCell
  • Weight: ​​1.05 pounds/pair
  • Included components: ‎Thermacell Rechargeable Heated Insole (Small)

2. Hotronic Footwarmer

Hotronic Footwarmer

Say goodbye to painful, frostbitten toes with Hotronic’s Foot Warmers, a product designed to keep your feet warm in cold weather even in extreme conditions down to -30C.

This warmer uses a heating element, to keep the blood circulation open, maintaining comfort and warmth in your foot, providing effective coverage of the toes, too.

The product comes with rechargeable Ni MH batteries and offers four heat settings for warmth, the fourth setting will give you an extra blast of heat, if you need it. 

The Hotronic’s work wonderfully, they act like toe warmers, meaning you’re not going to feel the heat, but you’ll feel them working. You’ll be able to enjoy a full day of skiing, not having to worry about your feet being cold or to adjust after turning them on.

The warmers will do their job and the long battery life will probably outlast you on the slopes. You’ll be able to ski with no breaks if that’s your style, the heat on the low setting will keep you warm for over 10 hours, while on medium setting will last up to 6 hours.

The warmers feature easy to read LED lights indicating the recharging mode, the setting selected and the battery charge status. 

Another cool feature is that the Ni MH batteries included in the package don’t have a “memory effect”, so they don’t need fully discharging before fully re-charging.

Also, you can travel worldwide on your skiing journeys, you won’t have to worry about compatibility with the charging system: Hotronic’s advanced global charging technology senses when the batteries are charged and protects them from overcharging damage by switching to trickle current re-charging.

One tricky part could be the installation of Hotronic’s warmers in the insoles of your boots, if you choose to do it yourself and not in a local skiing shop. The process could be easier if you warm your boots the night before.

For installing the warmers, you’ll need to cut a hole in your insoles, large enough to fit the end of the cord through, then thread the cable out and up along the spine of the boot to the top. 

You can choose the position of the battery pack, you can hold it with clips on the side of your boot on the velcro strap, or you can click it on the backside of your boot.

Keep in mind that these batteries are a bit bulky, about the size and weight of a pack of playing cards, so make sure that you account for that if the legs or gators of your ski pants are at all narrow.

The only downpoint is that the attaching mechanism is not secure enough, the batteries could loosen from your boot during chairlift rides, or while jumping, so you would risk losing them. So it would be great if Hotronic would offer more secure options for mounting them on the ski boots.

After you manage the installation part, the Hotronic’s Foot Warmers work like a charm, ensuring warm feet for the entire day, even in the coldest temperatures.

It’s a great product, highly recommended if you are struggling with cold toes while skiing and you need a top solution.

If you have low volume boots, you should apply them across and underneath your toes – making sure that they don’t go under the ball of your foot that would make your boot too tight and thus create a pressure issue.

Apply the warmers just under your toes and around and up and slightly over them to make sure that your low volume ski boots still fit.

Buying Guide

When deciding which ski boot heater is best for you, there are few criteria you’ll want to consider:

Battery Life

It is one of the top considerations, if you are interested to be covered for the whole ski day. Most ski boot heaters are powered with rechargeable batteries (NiMH batteries, Lithium Ion) or disposable AAA batteries.

How long the batteries last depends on the size of the battery pack and also on how high you set the temperature. Of course, if you set it up on the highest heat, you’ll have a shorter battery life. 

Also, you’ll want the batteries to be light, you don’t need extra bulky devices in addition to your ski gear, You’ll just need to find the right balance between the battery size and the battery power.

If you are going to spend all day on long skiing adventures, you’ll need a strong battery with heat lasting up to 17 hours, Therm-IC Insole Heat Kit is the best choice if you want a long-lasting boot heater. 

You’ll find the battery info and battery pack weight, and estimated size in the ‘Features’ section for all the products reviewed in this article.

Ease of Use

Another important factor when choosing the best ski boot heaters for you is how easy it is to use. Some boot heaters require installation, and you might need some crafting skills since you are supposed to attach the wires and batteries to your ski boots.

So before purchasing a product, make sure you are aware if it requires any installation or not. 

Among the heaters reviewed in this article, HotHands Toe Warmers is the easiest to use, since you just need to stick it to your ski socks, and there is no installation process, recharging, wires, or battery packs.

Do Ski Boot Warmers Work?

Yes, ski boot warmers work by delivering a nice toasty temperature to your toes. The heated insoles, and battery-operated heating elements installed under your foot, block the cold, maintaining good blood circulation, relieving foot fatigue, and offering extra warmth to your feet.

How Long Do Boot Heaters Last?

The duration depends a lot on the ski boot heater’s technology, type of battery or heating system. Also, it depends on how high you set the heating level. 

A standard ski boot heater offers 6 to 8 hours of heat, while there are products, like Thermic C-Pack, which can offer you up to 17 hours of heat.


Desperate times call for desperate measures! Some skiers also prefer to use a dryer to pre-heat their boots before heading out. So it’s a wise idea to invest in the dryer and warm socks for an extra dose of warmth. Ski boot heaters make ski boots more comfortable to wear.

Now that you have all the criteria to consider when choosing the right ski boot heater, you are ready to enjoy a comfy and warm ride on your next adventure!

My name is Laura Vrabie, and I consider myself a wonderer through this amazing journey called life. I love life in all its aspects, I always see the bright side of things. My love affair with extreme sports started with snowboarding about 15 years ago, in my home town in the Carpathian mountains. But everything changed about 5 years ago when I got to try a water sport that looked so fun, kitesurfing, during one boring summer day. I got totally hooked on the feelings of freedom, joy and pure happiness kitesurfing brought into my life Since then I started to chase summer all year round, following the wind & the waves, living as close as possible to the ocean. This way I got to try and enjoy all kinds of water sports: surfing, wakeboarding, scuba diving, sailing, kayaking. I founded KiteFest (kitesurfing festival & events) as a way to share the love for the kitesurfing lifestyle and to help everybody feel welcome in the riders' community. My quest is to discover and explore the best kitesurfing spots in the world and share them with like minded people. So far I've experienced kitesurfing in Zanzibar (Paje), Turkey (Gokceada, Akyaka, Urla), Greece (Limnos, Ionian Islands, Cyclades Island), Vietnam (Mui Ne), Philippines (Mindoro Island), Dominican Republic (Cabarete, Buen Hombre). And there are so many new locations and adventures on my wish list! I am really excited I got the chance to share in writing the stories and adventures with you, Extreme Nomads readers. I will be happy to guide you through these action sports and help you to enjoy your ride.
