The Best Foot Warmer: Our Picks

Guide: Questions to ask yourself before buying a foot warmer

What are the advantages of a foot warmer compared to the classic methods such as hot water bottles and heating pads?

When it comes to cold feet, many people still resort to classic methods such as hot water bottles, heating pads, warm foot spas or electric blankets. However, a foot warmer that has been specially designed for this purpose offers many advantages in comparison.

Hot water bottles can only warm your feet from one side. Foot warmers, on the other hand, allow you to warm your cold feet from all sides. The electric foot warmers, as well as the foot bags and grain shoes, enclose both feet.

This allows heat to be supplied from all sides. The self-adhesive heat inserts for shoes also allow all-round warmth due to the closed nature of the shoe. The foot warmer for shoes also allows you to get relief from cold feet outside. This is simply not possible with an electric blanket, hot water bottle or heating pad.

Another advantage of foot warmers is that they can also warm the limbs in a sitting position. All of the types presented can be used when working at a desk, for example. A hot water bottle is also unsuitable for this purpose, as you cannot normally place it on the floor and rest your feet on it.

In summary, a foot warmer offers you the following advantages compared to a hot water bottle:

  • All-round warmth
  • Suitable for outdoors
  • Suitable for sitting position

Are there also foot warmers with a massage function?

Some of the electric foot warmers are equipped with an additional massage function, which can additionally increase the well-being. This type of foot warmer has a massage function in addition to the usual heat therapy function.

These can be used separately. With most models, you can also choose between different levels. In this way, you can set yourself how warm the device should become and how strong the massage should be.

The massage function is not only for relaxation, but also has medical benefits: The feet are stimulated by the pressure and can thus warm up more quickly. So if your feet take longer to warm up, this device can be a practical help. The foot warmers with massage function have the same advantages and disadvantages as a normal electric foot warmer.

Did you know that the more muscles you have, the less you feel cold?

Since women have only 23% muscles, they freeze much more than men, who have 40% muscles.

Are foot warmers also suitable for everyday use at work?

If you are one of the many people who have trouble concentrating on work because your feet are always cold, foot warmers are the perfect solution for you.

Many professions, such as hunters, fishermen or construction workers, require you to spend a lot of time outdoors. If your job also requires you to work outdoors, foot warmers can be a useful investment for you. In this case, we recommend heated shoe insoles. They are flexible, can also be worn in work shoes and help you prevent discomfort.

But cold feet are also a nuisance in the office and can even impair your work performance. For these jobs, we recommend an electric foot warmer that you can plug in under your desk or a foot sack. If you have a microwave or an oven in the office, grain shoes can also be a suitable solution for you.

The Austrian army and police use heat pads to keep their feet warm in the fresh air, as do many professional skiers.

Decision: What types of foot warmers are there and which is the right one for you?

Basically, four different types of foot warmers can be distinguished:

  • Electric foot warmers
  • Warming pads for shoes
  • Grain shoes
  • Foot bags

The warming of the feet takes place in different ways with each of the types mentioned, so that they are characterised by individual advantages and disadvantages. Depending on how and where you want your feet to be warmed and what is most important to you, a different type of foot warmer is best suited for you.

In the following section, we would like to help you find out which type of foot warmer suits you best. To do this, we will introduce you to all the types of foot warmers mentioned above and clearly outline what their advantages and disadvantages are in each case.

How are the feet warmed with an electric foot warmer and what are its advantages and disadvantages?

The special advantage of an electric foot warmer is that you can choose between different temperature levels. This means that you can decide for yourself how quickly and intensively the device should heat your feet.

After you have plugged the power cable of the foot warmer into a socket, you can simply put both feet into the device and start the heat supply by pressing a button. The heat flows inwards via heating elements in the outer lining, keeping your feet warm from toe to heel.

The device protects itself from overheating with a safety function and stops supplying heat after ninety minutes. Nevertheless, the heat lasts longer because it is stored in the lined foot warmer. You can also remove the inner lining for washing and clean it by hand or at 30 degrees in the washing machine, depending on the manufacturer's instructions.

The electric foot warmers are very spacious and therefore also suitable for large feet. However, this also brings disadvantages for users with small feet, because a lot of heat is lost due to the unfilled space and this can also flow out easily at the sides.

Since the Footwarmer has to be plugged into a socket, you are also very limited in its use. In addition, the device is designed for a sitting position, which can become uncomfortable in the long run.

Advantages
  • Fast, even heating
  • Adjustable temperature levels
  • Protection against overheating
  • Easy to clean
  • Also suitable for large feet
Disadvantages
  • Heat loss for small feet
  • Restricted movement due to power cable

How do heat pads for shoes work and what are their advantages and disadvantages?

The special thing about heat pads is that you can use them outside. Whether you're doing winter sports or going to the Christmas market, you can take this type of foot warmer with you wherever you go. Even if you work outdoors a lot, heated pads are ideal for you.

As this foot warmer does not require electricity or charging, it is very easy to use: simply take the self-adhesive foot warmers out of the packaging and they will heat up by themselves through air activation.

You can then stick the warm insoles either on the soles of your feet or on the bottom of your socks. Then you can put on your shoes as usual. This foot warmer also keeps your feet warm for five to eight hours and is therefore suitable for anyone who spends a long time outdoors and does not want their toes or soles to freeze.

The sole warmers are very thin and available in different shoe sizes. This means they fit well in any shoe. They are also very reasonably priced and also available in value packs of several pairs. One disadvantage of heated pads for shoes, however, is that they are not reusable and therefore have to be disposed of after wearing them.

Advantages
  • Easy to use
  • Suitable for outdoors
  • Available in different sizes
  • Inexpensive
Disadvantages
  • Not reusable

How are grain shoes used and what are their advantages and disadvantages?

The special thing about these foot warmers is that they work with the proven concept of grain cushions and transfer this to the shoes. The plush shoes or plush socks are filled with grains and can be quickly heated in the microwave or oven. This way, they provide a cosy warm feeling that lasts for several hours.

The grain slippers, also called slippies, are available in different sizes, so you can choose a pair that suits you. You can also choose between different colours. The grain slippers are good for use at home on the sofa or in bed, as they are not tied to a power cable and you can therefore comfortably take them with you under the covers.

One disadvantage of the warming shoes is that you cannot walk around with them. So they are more suitable for sitting or lying down and can quickly break under strain. That's why they can't be washed.

In addition, you should pay special attention to high-quality workmanship. If the slippies are of poor quality, the grains can quickly leak.

Advantages
  • Easy to use
  • Available in different sizes
  • Suitable for sofa and bed
Disadvantages
  • Not suitable for walking
  • Leakage of the grains
  • Not washable

How does a footmuff work and what are its advantages and disadvantages?

A footmuff keeps the feet warm without creating artificial heat. The thick, cosy material warms the feet slowly in a natural way. This product group of foot warmers is therefore very environmentally friendly and harmless.

The footmuffs are available in a wide variety of designs and colours. Many are designed in funny animal designs, for example, and are therefore particularly suitable as gifts for friends and family members.

Depending on the manufacturer and material, most footmuffs are also washable. Depending on the manufacturer's specifications, some can be machine-washed at 30 degrees, others hand-washed. However, the foot bag is not suitable for walking as both feet have to be put into the bag.

Advantages
  • No artificial heat
  • Environmentally friendly
  • Multiple designs
  • Suitable as a gift
  • Washable
Disadvantages
  • Not suitable for running

Buying criteria: Use these factors to compare and rate foot warmers

In the following, we would like to show you which factors you can use to compare and evaluate foot warmers. This will make it easier for you to decide whether a particular product is suitable for you or not.

In summary, these are:

  • Heat generation
  • Heat regulation
  • Maximum power
  • Automatic switch-off
  • Material / Ingredients
  • Cleaning
  • Shoe size
  • Massage function
  • Application area
  • Design

In the following sections you can read about the individual purchase criteria and how you can classify them.

Heat generation

Each of the types of foot warmer presented here generates heat in a different way. Depending on your personal preferences and requirements for the product, you should choose a foot warmer that suits your individual needs.

With electric foot warmers, the heat is generated by electricity. This has the advantage that you only have to switch on the device to warm your feet quickly and evenly. However, you will of course have to pay extra for the electricity. In addition, the electric version is not particularly environmentally friendly.

The heated insoles work by natural oxidation of the iron powder they contain. This process is triggered by contact with the air and releases heat. The heating starts by itself after unpacking the pads. However, this process only works once, so the products can only be used once.

You heat the grain shoes either in the microwave or in the oven. Depending on how long you heat them, you can decide how warm you want them to get. However, heating them in the oven takes more time than with other foot warmers. This can be a nuisance when you come home frozen and have to wait until the slippers are warm.

The footmuff, on the other hand, does not need any artificial heat generation at all. Due to the closed shape of the product and the insulating material, your own body heat is stored and thus keeps your feet warm from heel to toe. This variant is both simple and environmentally friendly. However, it cannot reach temperatures as high as artificial heat.

Type Type of heat generation Advantages Disadvantages
Electric foot warmers Electric Fast, even Electricity costs, not environmentally friendly
Heat pads for the shoes Natural oxidation Easy to use Not reusable
Grain shoes Microwave, oven Temperature can be determined Time required
Foot bags No artificial heat generation Easy to use, environmentally friendly Lower temperatures

Heat regulation

Every person has a different perception of temperature. What is too hot for some may be quite comfortable for others. If it is important to you that you can regulate the temperature of your foot warmer yourself, you should choose an electric foot warmer or a pair of grain shoes.

You cannot regulate the temperature yourself with the heat inserts or the footbags. Most electric foot warmers have several different temperature settings. This means that you can set the temperature yourself at the touch of a button. However, you should always consider the performance of the product.

When you heat the grain shoes, you can decide for yourself how long you want to leave them in the microwave or oven. Depending on how much you heat them up, the temperature at which they can be used will also vary. So you can also regulate the heat level yourself with this product group of foot warmers, although it is a little more complicated than with the electric version.

Maximum power

The maximum power of your device is only important if you want to buy an electric foot warmer. Basically, you should pay attention to the wattage of the product when making your choice. A high wattage ensures fast and strong heating and is therefore recommended.

The higher the maximum power of a foot warmer, the faster it heats. Many customers find it particularly important that the device warms up quickly after starting and that you do not have to wait long for the effect. If this is also an important criterion for you, you should take a close look at the performance of the product.

Basically, it can be said that a maximum power of about 100 watts is suitable for an electric foot warmer in order to ensure a fast and sufficient heat development.

If you use this figure as a guide, you can better assess the effectiveness of the different models. Some foot warmers that are electrically operated also have a quick heating function that heats the device in a short time.

Almost all electric foot warmers that also offer a massage function, on the other hand, have a lower output. Due to the dual function, the performance of the device is greatly affected. As a result, these products also take longer to get warm and usually do not reach as high temperatures as foot warmers without a massage function.

Automatic switch-off

Almost all electric foot warmers have an integrated automatic switch-off that kicks in after ninety minutes of operation. This function is a safety measure and prevents the appliance from overheating. If you want to buy an electric foot warmer, you should make sure that this automatic switch-off is integrated.

There are risks associated with using an electric foot warmer, as with all electrically powered devices. The artificial heat generated can quickly cause the foot warmer to overheat and, in the worst case, cause a fire.

This is particularly dangerous if, for example, you fall asleep during use. This is why most manufacturers include this safety feature as standard.

When buying an electric foot warmer, make sure that it has an automatic switch-off function. This protects the device from overheating.

Material / ingredients

The materials of foot warmers differ greatly depending on the type. The material is a very important factor for every foot warmer: Ideally, it should be soft, breathable, insulating and gentle on the skin.

One of the most suitable materials for a foot warmer is therefore lambskin. It has natural and helpful properties that are ideal for this purpose. For example, it offers good insulation, but is breathable at the same time. Manufacturers of high-quality footbags in particular make use of this material.

So if a natural lining is important to you, you will be very happy with such a footmuff. Electric foot warmers and grain shoes, on the other hand, tend to rely on cheaper materials, such as fleece, polyester, cotton or synthetic fur.

In the case of heat pads, it is the ingredients rather than the outer material that are important. These are essentially the same for almost all products: usually the pads consist of vermiculite, salt, iron powder, activated charcoal and water in bound form. The ingredients are all non-toxic and therefore not harmful to the environment. Therefore, they can easily be disposed of in household waste.

Cleaning

A foot warmer can quickly become unhygienic, as the heat it generates can make your feet sweat. Therefore, it is very helpful if the foot warmer can be washed. If you want your product to be as easy to clean as possible, you should choose one of the washable models.

Most electric foot warmers have a removable inner lining. You can either clean it in the washing machine or wash it by hand. If it is too much work for you to wash your foot warmer by hand, you should make sure that your product can be put in the washing machine before you buy it.

The material of footmuffs is also very easy to care for in most cases. You can also clean this type of foot warmer either by hand or in the washing machine. Especially if you want to use the product regularly, you should take this aspect into account when making your choice.

Grain slippers, on the other hand, are usually not washable. Their delicate material with a grain filling makes them difficult to clean. However, if you don't use your foot warmer all the time and therefore don't necessarily need to wash it, the slippies are still an affordable alternative.

If you choose heated insoles, you don't have to worry about cleaning your foot warmer. Since the heated pads are disposable and you have to dispose of them after use, there is no need to wash them.

Shoe size

The question of shoe size is particularly relevant if you have either very small or very large feet. Before buying your foot warmer, find out exactly what size the product is available in to avoid problems when using it.

The electric foot warmers, as well as the foot bags, are usually available in a universal size and are designed for large feet. However, there is usually a limit here that lies between shoe size 45 and 48. As already mentioned, a lot of heat can be lost due to the excess space if you have very small feet. This limits the effectiveness of the foot warmer.

You can buy the grain slippers in your shoe size so that they fit snugly. However, they are usually only available in shoe sizes 36 to 45 or 46. Therefore, you should check whether the right size is available for you before buying.

You can choose between sole and toe warmers. The sole warmers are stuck under the socks or on the inside of the shoe like insoles. The toe warmers, on the other hand, are attached to the back of the foot.

The sole warmers are available in sizes S, M and L, but the range here also only extends from shoe size 36 to approx. 46. The toe warmers, on the other hand, are only available in one size because their small format means they fit on the back of every foot.

Massage function

As already mentioned, some electric foot warmers have an additional massage function. A great combination: warm feet that are also massaged. However, you should bear in mind that the heat function is no longer in the foreground with these devices and is therefore less intensive.

If you are looking for a feel-good and wellness product, the foot warmer with massage function is a suitable solution for you. The massage additionally stimulates your feet and thus stimulates the blood circulation. This device is a good choice for a cosy evening at home.

However, due to the additional massage function, less power is available for the heat output. As a result, these devices take longer to get warm and only reach lower temperatures. So if you really suffer from cold feet, a normal foot warmer is the better choice for you, as it heats faster and more intensively.

Note that foot warmers with massage function heat less intensively and are therefore not very suitable for you if you suffer from very cold feet.

Area of application

Before you buy a foot warmer, you should think carefully about where you want to use it. There are devices that you can use at home as well as products for outdoor use.

If you suffer from cold feet, especially outdoors, you should opt for heated insoles. As already mentioned, you can choose between sole and toe warmers. Depending on where exactly your feet are cold, one of the two options is better suited to your needs.

However, if you are one of those whose feet do not want to get warm at home or in the office, you should choose a different product. Here you have a wider choice: Electric foot warmers as well as grain shoes and foot bags can be used here.

Design

Even though a foot warmer is more of a utility item, it should still be nice to look at. The designs of foot warmers vary greatly and also depend on the type.

The electric foot warmers are usually kept in muted colours on the outside, such as beige, grey or brown. The inside is usually a white lining made of a cosy material. This makes these footwarmers look simple and cosy at the same time.

Since you wear the self-adhesive heat inserts inside your shoes, they are not visible from the outside. That is why these foot warmers do not have a special design, but are simply plain, flat heat pads with an adhesive side. They are usually white and therefore rather inconspicuous.

If you prefer a more exciting design, the grain shoes are ideal for you. They are available in a wide variety of colours and patterns. In addition to plain-coloured slippers, there are also grain shoes with animal patterns, for example in zebra or tiger look. The large and varied selection means there is something for both women and men.

The footbags are also available in different designs. The foot warmers made of lambskin tend to have a simple design. They are single-coloured, although you can also choose between muted and strong colours, such as red or blue. They also have a fold-down fur collar, which makes them very cosy and inviting.

If you prefer it fun and flashy, you can get a footmuff with an animal design. For example, there are models that look like a moose, a sheep or a cat. Footmuffs in these funny designs also make great gifts.

It's especially important to keep your feet warm in the cold season. Cold feet make you more susceptible to catching a cold. Especially for people who get cold easily, the foot warmer is very beneficial. (Photo: yarruta / 123rf.com)
