Buying Guide

You need to think through several points before deciding on the best foot warmer for yourself. For example, the types, how safe they are, and the impact they may have on the environment.


There are currently 3 main foot warmer types: wearables, heating pads, and heat packs.

Heat packs

These are the best if you want to go out for a while in the cold as they are small and incredibly portable.

In addition, these are made from water, salt, iron, and carbon, producing heat through an extremely fast oxidation process. Thus, there is no way that they can be bad for the environment.

However, they are usually single-use, so that can be a downside.

Heating pads

These are often electric pads that we need to plug into some outlet in order to work. As power is not a problem, they can offer the luxury of several heating options. In addition, some of them even have additional features such as massaging.


These are usually slippers or socks, as long as they can give off heat. In most cases, they are accompanied by a rechargeable battery, so they can last quite long.

There is nothing more important while shopping for foot warmers than checking their safety features. You must always remember that these are heat sources contacting directly with your body. Thus, precaution is the most vital priority.

First of all, you need to read the manual instruction that comes with any warmer you get. Usually, they will warn against applying the warmer to your skin. Consequently, the best method is having socks or towels acting as barriers between the skin and the heat source.

The moment you feel that the warmer’s heat is too intense, immediately stop using it and check its settings if you can.


These days, the impact on the environment has become a major concern when we make our purchase. Single-use heat packs can be a problem out of the three types. After all, they can stack up and take up a large proportion of landfills.

Of course, there have been companies that realized this problem and start using natural ingredients. However, it is still not good enough. Thus, if the environment is a big issue for you, heating pads or wearables that operate on electricity are great!

Are foot warmers safe?

Yes. However, you must not let them touch your skin directly. After all, they are still sources of heat, so it is always better to be safe than sorry.

Additionally, heat packs are mostly made from natural ingredients. Thus, the heating process will not produce any bad substance for your health.

How long do foot warmers last?

This depends on the type you get. Heat packs can last anywhere between five and eight hours most of the time. Of course, heating pads and wearables will last as long as they have a power supply.

How hot do foot warmers get?

For the heating packs, as they create heat through oxidation, the heat can vary. However, they rarely go past the 165 degrees Fahrenheit mark. As for the heating pads, they usually have heat settings, which let you customize the temperature.

Of course, you still do not want them contacting your skin directly.

Is a heating pad good for foot pain?

There are many approaches that one can take to treat foot pain, hot therapy is one of them. The heating pad is a great tool that you can use for the hot therapy solution.

Additionally, these days manufacturers can include many useful features to the heating pads. For instance, one of the most popular features is massaging, which can help tremendously with blood circulation.

How do you use foot warmers?

For the heat packs, you simply put them to the body part that you want to be heated. No direct contact, though. It is the same case for the wearables as you simply have to wear them. As for the heating pads, you need to plug them in, choose the appropriate settings, and that’s all.


After checking through all of the requirements, we believe that the Serta Ultra Soft Plush Electric Heated Warming Pad is the best. Firstly, it is really versatile, as you can use it to heat many parts of your body, not just your feet. Next, you can use it for a long time, so there is no waste. Lastly, it is also quite safe.
