The battery is not actually a built-in one but it can be attached to the top of your boots which is barely noticeable.

This boot heater is an entirely different product when compared to the ones I have mentioned before.

DryGuy DX Forced Air Boot Dryer is the product onto which you put your boots on so that it heats and removes moisture from the boot. It can heat the boots or any garments up to 105 degrees celsius and even kills the bacteria residing inside them.

Its mechanism contains a quiet rotary blower which warms up the garments quietly and even has a timer of 3 hours. Usually, it just takes 1 – 2 hours to completely heat up the boots or garments which makes this product good for ski lodges or public places. But if you want to make the most of a good skiing day, this product is not completely recommended as it takes up more time and most importantly cannot be fit inside the boots.

  • Can be carried anywhere

Buying Guide – what to look for?

Every detail you need to know about ski boot heaters has been explained thoroughly listed along with the best 5 products. Even though you would still be confused about which one to pick yet. There are various kinds of factors to look at when purchasing the right foot warmer but some features are essential to look out for. This section is entirely dedicated to clear your doubts on which kind of ski boot heaters are best.


Size is essentially the first thing you should notice. There are different boot warmers that are available in different sizes which the users can purchase as per convenience. But it is highly recommended that you purchase a boot warmer that has a universal fit size which means that it can be trimmed as per our convenience and can be fitted into any kind of boots or shoes. It will be an added advantage that when you purchase online, you may not get the appropriate size but if it is a universal one, you can customize it as per wish. Also, make sure the product has good flexibility to fit into any type of footwear.

Battery life

Some users get confused about what actually battery life means. there is a big difference between the capacity of a battery and the life of the battery. Some batteries have enough capacity to provide warmth continuously for 21 hours in one charge but have a life of 100 – 200 recharges only, while some batteries provide a performance time of 5-6 hours in one charge but can be recharged over 500 times. So it is essential to look out for battery life and capacity and don’t get fooled they are the same. Also, the different modes of heat setting determine the battery juice as a high setting drains the battery easily while a low setting can prolong the juice. So choose a product with good battery life and based on your usage of the product.


Well, the cost is the foremost thing everyone notices while selecting a product or brand. But it is necessary that you don’t compromise with the quality just because the price is a little bit higher. If the quality is compromised, you can maybe use the product for just one skiing season only, which is absolutely a waste of money. Lookout for branded ones like the ones I have listed above or if you prefer other brands you can search for better ones like Therm-ic.  Some ski boot heaters are remote controlled which makes them a little bit expensive but it is worth it because of their comfortability.

Heat setting modes

Most of the ski boot heaters have three different modes of heat settings – low, medium, and high. But some heaters have a fourth mode of heat setting, which provides short bursts of heat periodically. Such a type of heater is best recommended as it conserves battery life and prevents the battery from overheating. The lowest heat modes conserve battery juice but the highest mode drains battery life very fast. With the help of advanced technology, you can switch between different heat modes with the help of a wireless remote. For good results, choose a heater having at least 3 different types of heat modes.

Ease of use and installation

Some heaters claim to be advanced in technology but they are sophisticated in working. It may contain a long instruction manual about the working and all those unnecessary instructions which may confuse you. So it’s the best option that you choose for a product that is easy to use and compact in design too.

Most ski boot heaters are designed in the form of insoles or socks with a battery fitted inside or attached with a wire kept outside the boot. Heaters with inbuilt batteries are the best option because it is covered with polymer materials to withstand impact and it would not be much noticeable to external eyes.


Most of the customers do not care much about the warranty but that’s usually a bad move. Warranty is not available for most ski boot heaters. Always opt for ski boot heaters having a warranty of at least 1 year because it has been noted that most parts die out and do not have the durability it claims. With the help of a warranty card, you can replace the battery or any damaged parts within the product.
