Best Ski Boot Heaters


This is my review of the best ski boot heaters.

Nothing ruins a ski day like cold feet. Regardless of how much time you spend out on the slopes or how much you have planned, cold toes can end a trip early.

However, just because it’s cold out, doesn’t mean you have to suffer. There are many ways to keep your feet toasty while skiing and one of the best is a good boot heater.

Boot heaters are battery-operated devices that sit inside your shoe and add extra heat to your feet and toes. That ensures you can ski in comfort, no matter how low the temperatures drop or how much snow falls down.

You may think your boots are enough in terms of cold protection, but even the best models can use a little extra help when conditions get rough.

The following heaters do a great job of keeping your toes toasty. They each have unique features on top of excellent construction and advanced heating capabilities. That doesn’t just make your boots much more comfortable to wear, it enhances your entire skiing experience.

This guide will break down what makes the best heaters so special and why they excel where similar models do not.

Quick Summary

  • The small Therm-ic rc 1600 may not look impressive at first glance, but it packs quite a punch. The handy product excels at every level, making it the best option for more serious skiers who value features. The device provides you with a stunning 22 hours of battery life on top of a quick-charging system and global charger that works anywhere on Earth. If you want all of the bells and whistles, this should be your battery of choice.
  • If you value versatility, the ThermaCell ProFlex is the ski boot heater for you. This works with many different shoe types and comes with a flexible insole that can be trimmed to reach the best fit possible. In addition, the heater lasts for five hours. That might not be the longest charge out there, but with 500 charges, it’s perfect for skiers who value durability. It’s also great for skiers who want a long-lasting device.
  • The ThermaCell Heated Insole is the perfect heater for those who want to save a few bucks. The affordable model offers two different heat settings, charges quickly, and has a long-lasting battery good for 500 charges. Though you’re not going to get all of the exceptional features you’ll see in some of the more expensive models, this heated insole is more than worth the price. The included remote makes it easy to use as well.
  • Another fantastic Therm-ic Model, the Classic Super Max is the best heater for skiers who need help in the extreme cold. As with other Thermic heaters, this has impulse control that helps you stay warm by promoting circulation. The durable heater keeps your boots warm for eighteen hours at a time and does so at high temperatures that prevent your boot from succumbing to winter temperatures.
  • While many heaters on this list are geared towards heavy-duty conditions as a way to combat freezing temperatures, sometimes you only need a little bit of warmth for an easy run. That’s where the Hotronic FootWarmer comes in. This versatile heater has four heat settings, a long-lasting battery that goes for over 20 hours on low, as well as an LED light indicator that shows you how much battery you have left.
  • If you want comfort, the Dr. Warm Heated Insole is the way to go. While not as well known as the other options on this list, the heater feels great to walk and ski on, no matter how hard you ride. The ergonomic design softens impacts, while the material can be trimmed to fit any boot. If that’s not enough, the durable construction holds up for years, the remote control is easy to operate, and there’s even an included USB charger.

Who Should Get This?

Heaters are great additions to any ski boot. Skiers who have cold feet or who tend to find themselves extra chilly while out on the mountain will do well to pick one up. Normal boot insulation works for certain people, but it doesn’t hold up for everyone.

Every skier at every level can appreciate what a good heater brings to the table. However, the items are typically suited for skiers who like to brave fierce or harsh elements.

Extra warmth is not always needed on a groomed resort run. However, it can be a life-saver when braving the backcountry or crashing through deep powder on the far side of the mountain.

The ThermaCell Proflex Heavy Duty is the best ski boot heater for those who want a sleek, easy-to-use design. This is similar to the regular ThermaCell Proflex in many ways but differs in that the battery is built directly into the insole.

That means there are no wires to deal with, nor do you need an extra battery. Everything’s contained in one place. As an added bonus, this self-contained model can also be controlled through an extremely handy smartphone app.

Best Ski Boot Heaters in 2021: What to Consider?

Take a look at the list of factors below which will help you better choose the right ski boot heater.


Boot heaters are great skiing accessories, but you want to ensure they feel good when you wear them. Many premium models come with great features, but that doesn’t mean they’ll work with your boots.

Pay attention to how thick your heater is and if that will work for your skiing style. Some people don’t mind a thicker model, while some people only want a thin heater that they’ll barely notice. What you go with is completely up to you.


Weight is another important heater aspect that goes hand-in-hand with thickness. Some heaters might have solid attributes and a good thickness, but they may be too heavy. When picking out your model, get something that won’t weigh you down or hold you back.

In fact, you want to get the lightest possible option. Skiing takes quite a bit of effort. It doesn’t matter if you’re zipping down a groomed run or exploring the backcountry, you want as little weight as possible.

Battery Life

Always pay attention to your heater’s battery life. Every model provides warmth, but they all do it for different periods of time. Some heaters will hold their charge for an entire day, while some models will only give you a few runs.

In that same vein, note that every battery delivers power on different settings. Some will only last a few hours on high but could stick around for hours on medium or low. Go with the one that best suits your individual style.

Heat Settings

In the same way, you look at batteries, you need to pay attention to heat settings. Every ski boot heater has a range of settings aimed at tackling different temperatures and environments.

Your goal is to get settings that best match your ski style. If you like to tackle tough conditions, you need various heat settings that provide you with more versatility. However, if you stick to pleasant days, you need less nuance.

Ease of Use

A good heater goes a long way, but only if you can properly use it. There are many heaters on the market that come with a lot of features. However, many of them are quite difficult to use.

Do your best to get models that are easy to set up and implement out on the mountain. Some heaters have remotes, while others sync to your smartphone. If you love tech options, those are the best way to go.

Ski Conditions

Though it’s easy to overlook, you should always pay attention to what conditions you typically ski in when choosing your boot heater. There are many different heaters out there, and they each help with a certain type of terrain.

Pick the amount of warmth you need for the conditions you most often ski in. Subzero temperatures require strong warmers to fight the frigid cold, while calm, sunny conditions require something much milder.

Useful Tips

Ski boot heaters are one of the best ways to keep your feet warm when zipping around the mountain. However, they are far from the only way to stay toasty in frigid temperatures. In fact, there are many other ways to lock out the cold during a ski run. Check out this video if you want to explore them.

Ski boot warmers are fantastic, especially when paired with heated ski socks. Though not quite as sturdy as the above models on their own, the socks do work well when put into boots with other handy accessories.

If you’re curious about which ones work the best, check out this heated ski sock review to get more information.

The above two links mainly focus on other ways to ensure your feet stay warm. However, you should keep your body comfortable as well. That’s a bit more of an involved process, but it’s just as important. That is where the tips in this guide come in handy.

Once you get a heater, you may also be curious about the best way to actually put it into your shoe. Though the above models tend to be easy to operate, it always helps to have some instructions to make your life just a little bit easier.

Final Words

Ski boot heaters may not be the first accessory you think of when it comes to skiing, but they go a long, long way towards keeping you comfortable. It gets extremely cold in the winter. While many people simply assume they have to suffer when their socks or boots won’t cut it, that is not the case.

All of the different options outlined in this guide provide excellent warmth for extended periods of time. They have great features and work on just about any mountain. However, they all have their own specialties as well.

Though you can mix and match the above heaters, it’s best to get the one that fits the way you ski. You may need extra warmth, added durability, or intense heat. In contrast, you may only want something for bright, clear days. Always do your research before making your final decision.
