Buying guide for Best heated insoles

Heated insoles serve two purposes: they improve the fit of your shoes, and they help keep your feet warm.

Heated insoles are removable, and they can generally be used in all types of shoes. Many people find them to be must-haves in the winter — especially those who engage in winter sports like skiing and snowboarding.

If you enjoy spending long periods of time outdoors in the cold, heated insoles help reduce the risk of uncomfortable feet and toes.

Some heated insoles are sold in small, medium, and large sizes. Each size accommodates individuals across a set range of shoe sizes, so you’ll want to check to make sure you’re ordering the correct size.

Heated insole features

Let's first consider some of the key features to evaluate as you shop for heated insoles.

Number of uses: For those who prefer one-and-done heated insoles, single-use options are available that provide up to nine hours of warmth. Battery-operated heated insoles are also available; these insoles come with a rechargeable battery that delivers all-day warmth.

Adhesive: Heated insoles commonly include self-adhesive covers and strips that help keep them in place.

Base-level settings: If you pick up electric heated insoles, you will probably be able to take advantage of different base-level settings. These settings allow you to adjust the heat level.

Activation: Single-use heated insoles are usually activated by shaking the insoles in air, while battery-operated insoles can be activated with the push of a button. Both types of heated insoles tend to heat up within 15 to 30 minutes of activation.

Design: Heated insoles are usually thin and able to fit in large or small shoes and boots. In certain instances, the insoles may need to be trimmed so they fit comfortably inside your footwear.

Eco-friendly: If you're on the lookout for environmentally friendly heated insoles, options are available that contain eco-friendly components. For example, you might purchase a pair of reusable heated insoles that can be washed. Just be sure not to expose any electrical or battery components to water!

Quantity: Single-use heated insoles are frequently sold in packages that contain up to 30 pairs.

Batteries: Electric heated insoles often use lithium-ion polymer batteries. These batteries sometimes require a few hours to charge, but they can be recharged hundreds of times before they need to be replaced.

Water resistance: No one wants heated insoles that stop working if they get wet. If you plan to spend lots of time playing in the snow, it is generally a good idea to pick up water-resistant heated insoles.

Safe and easy to throw away: Single-use heated insoles are often made of materials that won't harm the environment, and you can dispose of these insoles in the same way you would dispose of everyday garbage.

Electric heated insoles are sometimes sold with a remote control that allows you to turn them on and off, even if they are not currently on your feet.

Heated insole prices

The upfront cost of single-use heated insoles is lower than that of electric varieties. Keep in mind, however, that electric heated insoles may perform for years, whereas single-use heated insoles are only good for the very short term.

Inexpensive: The most affordable heated insoles cost less than $20. These heated insoles are usually disposable and tend to be sold in packages of 10 pairs or fewer.

Mid-range: These heated insoles are available from $20 to $80. You’ll find both single-use and electric varieties here. Single-use heated insoles may come in packages of 30 to 60 pairs. Electric heated insoles are usually lightweight and designed for use in lots of different types of shoes.

High-end: The priciest heated insoles may cost up to $200. These are electric and offer a rechargeable battery pack, multiple heating elements, and other state-of-the-art features.


  • Consider how you will use your heated insoles. If you require heated insoles for a short ski trip, single-use options may be ideal. Conversely, if you plan to use your heated insoles for several winters in a row, a pair of electrically heated insoles may be the best choice.

  • Evaluate the size. If you're at the top of a mountain and need to quickly insert a pair of heated insoles in your boots, you probably won't have time to trim them down for an optimal fit. Evaluate the size of heated insoles before you buy them. One-size-fits-all options are available.

  • Analyze the recharge time. Electric heated insoles usually recharge in four hours or less. So, if you want electric heated insoles you can recharge during your all-day drive to the mountains, these insoles may be right for you.

  • Assess your footwear. If you plan to use your heated insoles inside your big, heavy ski boots, be sure to buy insoles that will fit comfortably inside your boots. You can use your boots' current insoles to get an idea of the right size.

  • Set realistic expectations. If you expect your heated insoles to start working right out of the package, think again. Remember, you need to activate your heated insoles, so it may take a few minutes before you start to feel your insoles warm your feet.

  • Follow the instructions. Heated insole instructions are critical, especially for those who want to enjoy all-day warmth. Fortunately, instructions are usually included with the packaging, and if you follow these instructions, you can reap the full benefits of the product.

Some insoles are designed for support; others are created more for your comfort. Supportive insoles are commonly made of hard materials and are designed for individuals with plantar fasciitis, pronation, and other foot issues. Comfort insoles may consist of gel or foam.


Q. What are insoles exactly?

A. The insole refers to the inner part of the shoe. It runs along the bottom of the foot and provides support. Insoles are included in all shoes, and they are commonly constructed from cellulose paperboard or synthetic materials.

If you find your shoes are uncomfortable, replacing the insoles may help. Heated insoles and other custom insoles are available, and these products can help support the feet.

Q. Can children use heated insoles?

A. Yes. Heated insoles are available for individuals of all ages. But they sometimes come in different sizes, so be sure to pick heated insoles based on your shoe size.

Q. I tend to stay active in the wintertime. Will my heated insoles stay in place?

A. The best heated insoles are equipped with an adhesive that you can use to firmly attach them to your shoes. You can wear them while you ski, snowboard, run, walk, and perform other outdoor winter activities without having to worry about your feet getting cold.
