I hate the feeling of cold feet. My toes feel stiff and numb, and the skin around my heel hardens up. If it is cold enough, my entire ankle feels sore like arthritis. And sometimes, the pain from the cold can be so intense that it goes all the way up to my knee. So when wintertime comes, you always find me in a pair of reinforced thermal socks. You can say that keeping my toes and feet warm is one of the most important priorities in the wintertime for me. But I don’t have this problem when I go skiing. Now that may make you think,” maybe his feet have already gone numb.” How can I be perfectly fine in Sub-Zero temperatures while my heart content while I suffer at home in 60-degree weather? The answer is simple: I use battery power boot warmers whenever I go skiing. They keep me warm and dry the entire time I’m on the slopes. But there are so many different types of ski boot warmers available to purchase. Which ones should l buy? Many people ask me these questions, but there is no easy answer because everyone has different ski boot needs. So if you wish to know which are the best foot warmers, keep on reading!

What Is A Ski Boot Warmer?

Dealing with the cold is one of the worst aspects of playing in the winter. To me, a little bit of cold is okay, but if my hands go numb within a few minutes of being outside, I would rather be inside drinking hot chocolate! So it is a good thing that skiers and snowboarders have high-quality, technologically-advanced clothing to keep them warm. Now the only part of your body that has to deal with the cold is your naked face, which is only protected by goggles and your feet when you change from your regular winter boots into your ski boots before you jump on that chair lift. But now, you can buy a ski boot warmer, and you’ll never have to deal with cold boots ever again. 

A ski boot warmer is a heated device that you can insert directly into your ski boots to keep your feet warm. If you were to look up ski boot warmers on Google, you would say that they come in several shapes and sizes, so there is one size that fits every person’s needs. But you must do some serious searching to find the one that is right for you.

Do not confuse a ski boot warmer with a heated ski boot bag. The boot bag is a heated bag that generates heat inside of it to keep your entire boots and any other objects inside the bag warm. However, a heated ski boot bag is an amazing investment. Some bags have a large pocket where you place your ski boots to be heated, and other bags just heat the entire bag, so everything inside is warm and toasty, including your ski boots if you like warm ski gloves, or a toasty scarf, you should consider purchasing one.

When you use warmers for ski boots, your skiing experience will be more comfortable and luxurious. A skier does not have to use a ski boot warmer, but many who try it out never want to go back to cold boots and socks again. There is just something special about sliding on a velvety warm boot when the weather is 20 degrees and dropping. A ski boot warmer is also a great way to protect your toes from frostbite. While you are skiing, if your boots are damaged or ripped, and the freezing wind can get into your boot, your toes will be protected by the boot warmer. 

What Else Can Be Used To Keep My Feet Warm?

The best toe warmer ski boots are ones that are light and inexpensive and can fit in your boots without squishing your toes. But boot warmers are not the only item that will keep your feet warm.

Socks are an indispensable part of your ski outfits, and using any old pair of socks just won’t do.

Foot warmers for ski boots work best when paired with a thick sock made for winter sports. Socks that are made for Sub-Zero temperatures and winter sports socks are not as cheap as regular socks, but they get the job done. Winter socks hold your body heat in better and absorb your sweat. Some socks even have extra padding around the toes and the heel, so when you use your feet to slow your skis or stop altogether, these parts of your feet will have extra protection. So if you don’t have a pair of skiing or winter sports socks, purchase them when you go shopping for your ski boot warmer.

Features To Consider

When you are considering what is the best ski boot warmer, think back and consider all the different factors that influence your ski boots and how much cold your feet and toes can take. You should also consider your boots’ size and how much room you have leftover to include a pair of ski boot warmers. If searching for a new pair of ski boots, this is the perfect time to find a pair of ski boot warmers that can fit perfectly into your boot with your foot.

Battery Life

For a ski boot warmer to work, they must have a well made high-quality battery that has at least 4 hours of the warming energy per charge. If you spend far more time skiing then only 4 hours, you may want to invest in an expensive ski boot warmer with longer battery life, or you can purchase two different ski boot warmers and use the second one when the first one burns out. When you first test the battery by charging your ski boot warmer, you need to note how long it takes for the warmer to reach a full charge. If it takes all night to charge the battery, you may want to look into a different warmer.


Although your ski boot warmer will be safe inside your boot, they need to be durable and handle your weight. But a ski boot warmer also must be able to handle moisture and liquid. If your water accidentally lands in the snow, it should not cause it to immediately short out and fail. As long as the pads are not submerged in water completely, it should be fine. But the snow is not the only problem when it comes to moisture. The sweat from your foot should not be able to short-circuit your boot warmers. Even if your boot lining is a sweaty mess after a long day of skiing, your ski boot warmers always need to remain functional.

Heat settings

There should not be only one heat setting on your ski boot warmers. You need far more than an on and off button. There will be some times when you must have a lot of extra heat because of the freezing temperatures outside. But if you like to ski in the late spring, you might only need a light warm from the ski boot warmers. If you use a ski boot warmer with only one setting, there will be times where your feet will either be too hot or not warm. Plus, the more you move, the less you will need your warmer. So, you will want to lower the setting then. But when you stop to rest or sit, you’ll want to raise the heat, so you stay warm,

Ease of use

Some of the ski boot warmers in the next section look like they’re from the future. Some Of these devices just look like a tangled mess of wires and pads. Despite how complex they look, ski boot warmers should be easy to use. When you purchase one, purchase one that you find easy to operate and easy to add to your boots.


The weight of the average ski boot warmer should not be a problem. Most of them are less than one pound each. In fact, you will find these warmers are usually around 4 to 8 oz. The weight of the warmers may impact the speed at which your feet move while you are making turns, and the weight can also affect your balance. But as long as you developed decent leg muscles over months of skiing, you shouldn’t have a problem.

Extra room

Even if you find an amazing pair of ski boot warmers on sale for 75% of its usual price, you should not purchase it if your foot is squished inside your boots. A skier needs to have enough room in their boot for their foot to move around but not so much room that it is loose. Farmers may be small and flat, but if your ski boot does not have enough room in the first place, the fit around your foot will be tight.

Speed of charge

It should not take long for you to recharge your padded insoles or ski boot warmers when you need to do so. The charge should not last longer than its battery life. If a pair of insoles last eight hours, they should charge to 100% completion in 6 hours or less. If ski boot warmers that you choose only last for hours, then look for a pair with extra batteries.

How To Clean Ski Boot Warmers

Since you are dealing with a battery power warmer that will spend hours inside your shoes and boots, you should know how to clean them. Not only will it become dirty from use, but the sweat and odor from your feet will dirty the warming pads. These items need to be washed every one to two uses, especially if you want to keep the odor from building within the material. Unlike boot liners and your socks, you just can’t throw ski boot warmers into the washer. They must be hand washed and left to dry out in the open air. 

When you do wash your warming pads, do not leave them in water. That will also short-circuit the wiring isn’t the pads, and they will be going usable. Now that you understand what not to do, let’s go over to how to clean your ski boot warmers, so they stay clean and ready whenever you need them.

Unless the ski boot electric warmers provide different instructions on how to clean them, all you need is a damp washcloth and some soap. First, submerge the washcloth and warm water and wring it out well. It should not be dripping wet; it needs to be damp. Now, take the washcloth and rub the surface of the ski boot warming pads lightly. Wash the entire pad with small circular strokes, and don’t forget to do the bottom part as well. If you wipe down your ski boot warmers every one to two uses, you may not need to use soap. Now that you’re boot warmers dry. 

When they are completely dry, smell them and see if the order is gone. If there is no odor, then you are done; you can pack them away in your bag for your next big ski session. But if there is an odor, you will need to wash them again and, this time, add a small house soap to the washcloth. 

After adding soap, scrub it again in small circular strokes. Make sure you see the soap buildup on the pad. Even though there’s soap on the washcloth, the clock cannot be wet. The washcloth should still only be damp. 

When you are done scrubbing the warmers with the soap, rinse out the washcloth, and wash off all the soap. Once again, allow them to air dry. There should not be any smell when you sniff the warming pads.


The feeling of heated pads inside your boots will be strange at first. When you are used to the feeling, you’ll love the way your toes feel as they are all warm and toasty. As I mentioned above, when you find the warmers you want, look for a pack with extra batteries. Extra batteries will keep you warmer longer, or you won’t have to charge your only pair of batteries every night. Ski boot warmers come in all shapes and sizes, but there may be some that are completely incompatible with the shape of your boot. Although, some can be trimmed down and reshaped, so keep an eye out for those two. No matter what, just keep your feet and your little toes safe from the cold. There’s nothing worse than feeling the stinging pain of Sub-Zero weather and realizing that you will soon develop frostbite because of poor protection.
