Buying guide for Best heated socks

Nothing makes you feel all cozy and comfortable like warm feet. Sometimes, though, you just don't have the option of throwing on a blanket to get toasty. A pair of heated socks will do the trick no matter where you are. But if you've never purchased heated socks before, you might not know what to look for.

The best heated socks have an easily accessible rechargeable battery that lasts for an extended period of time. They fit comfortably inside your desired footwear, are washable, have adjustable temperatures, and, for device savvy individuals, feature Bluetooth connectivity. If you will be wearing them outside, waterproof socks with reinforced seams are desired.

Many heated socks are unisex. As such, a woman might need a size smaller than her normal shoe size to get the right fit.

  • Hiking

  • Winter camping  

  • Outdoor work

  • Hunting

  • Motorcycle riding

  • Skiing, snowboarding, and other winter sports

How heated socks work

Most heated socks are either battery-powered or require an outlet and feature some kind of heating element to warm up your soles and toes. Some heated socks geared toward motorcycle enthusiasts plug right into the motorbike for power. Some budget models can also be used with throw-away foot warmers.


Many heated socks are battery-powered and come with batteries, so they're ready to use right out of the box. Before settling on a specific pair, make sure the required batteries are simple to replace and find in stores. Look for socks with battery packs that are easy to snap off and open.

Rechargeable batteries

Some heated socks come with rechargeable batteries. These offer more convenience and are useful for long, multi-day trips since they can be powered on the go with a portable charger or any available outlet. Check manufacturer details to find out how long the battery is supposed to last. The advertised battery life should be taken with a grain of salt since it’s usually measured at the lowest settings and in ideal conditions.

Disposable warmers

Not all heated socks require batteries. Some are meant to hold the kind of disposable warmers you might find at the dollar store. These socks feature small pockets to hold the warmers. These heated socks are cheaper to buy than battery-powered units, but the cost of the disposable warmers can add up over time.

Heated sock features to consider


How will you use your new pair of toasty heated socks? Your answer will help dictate the kind of socks you need.

  • For indoor use, waterproofing isn’t necessary, but outdoor excursions may require socks that repel water.

  • Battery life is important to consider, especially if you plan on heading out for a multi-day adventure.

  • For long-lasting outdoor activities, a thicker sock might be worth considering just in case the battery doesn’t last all day.

  • Motorcycle riders and skiers looking for a warming sock should make sure the socks fit comfortably inside riding or ski boots.

"When choosing a pair of heated socks for outdoor use, consider whether you'll be wearing shoes or boots. If you’ll be wearing boots, make sure the battery pack sits above your boot tops."


Most heated socks allow you to adjust the temperature. Some even come with a remote so you can change the temperature without having to bend down to fiddle with the battery pack.

Most heated socks feature three heat levels (low, medium, and high), but not all models provide warmth throughout the sock. Check to see where the heating element snakes through the sock. Most heated socks warm up the sole of the foot, but for extra coverage, look for models that warm the toes as well.


Like any kind of sock, a heated sock should fit well. The sock should hug your foot without cutting off your circulation. It shouldn’t bunch up or pinch anywhere. When you move, the sock shouldn’t slip or slide inside your footwear.

"Battery packs can cause the tops of the heated socks to roll down. Make sure the fit is secure. Some models have a cinch-top design to help the socks stay put at the cuff."


Heated socks are a little more delicate than regular socks. Most can be put through the washing machine, as long as you take care to remove the battery pack. Quite a few models feature convenient snap-off battery packs. If you're not sure if you can wash the socks, check the care instructions to make sure they can be machine washed. Avoid throwing any heated sock in the dryer.


Sock thickness is a personal preference that depends, in part, on how you intend to use your heated socks. A chunky knit sock, for instance, might not be appropriate for a ski boot, so you might opt for a liner-type sock instead. Always consider your footwear when picking a sock for any activity – unless you plan to only use your heated socks indoors.

"Don't take battery-life claims at face value. Advertised battery life is usually measured using the lowest heat setting. "

Bluetooth connectivity

Some heated socks work with smartphone apps via Bluetooth. These high-tech models allow you to check the remaining battery life and adjust the heat levels. It’s a neat functionality, but heated socks with this feature can be quite expensive.

Moisture wicking

Even if you aren’t going to be doing physical activity while wearing your heated socks, breathable fabric will add to your comfort. Avoid socks made of cotton because it doesn’t dry very quickly. When cotton gets wet, it stays wet. Synthetic materials, fabric blends, and Merino wool are all great options to consider.

"Some heated socks use both battery power and disposable warmers for double the heating capacity."


Some heated socks come with the added benefit of compression, which helps improve circulation by increasing blood flow. These medical-grade socks are suitable for those with illnesses like diabetes or Raynaud’s disease.


While most heated socks come with built-in safety mechanisms, some models have added safety features like auto shut-off, which automatically switches off the heating mechanism after it reaches a certain temperature or after it runs for a specific amount of time. Some models also have waterproofing that protects the heating element in the socks. These models are useful for activities like fishing.

For your safety
Those with circulation issues such as diabetes should be cautious when using heated socks. Poor circulation can cause numbness, and a loss of feeling can increase the risk of burns.

Heated sock prices

Under $100: In this price range, you’ll find battery-powered and plug-in models with decent battery life (around four to eight hours). Models at this price point may feature smaller heating elements.   

Over $100: Higher-end heated socks feature rechargeable batteries and include such features as Bluetooth connectivity. For a higher price, you'll also find pairs with better battery life. Pricier models may also provide more heating coverage.


Heated socks are generally safe to use, but as with any kind of equipment that utilizes batteries or electrical power, it’s a good idea to keep a few safety tips in mind.

  • Don’t submerge your heated socks in water unless they’re explicitly made for wading activities like fishing. For water-oriented activities, consider a pair of socks with a corded battery pack that can be placed on your waist or in a jacket pocket so the batteries don’t get wet.

  • Don’t wash the battery pack.

  • Avoid very cheap heated sock options. Poor construction can become a safety hazard.

If you’re going on a long hike and worried about battery power, take along a portable charger so you can relax knowing your socks will keep you warm throughout your journey.


Q. Is it safe to use heated socks?
Yes. Most heated socks have some kind of backup mechanism that shuts off the heating element if there’s a malfunction or mishap. Heated clothing also uses fairly low voltage to warm your extremities, thus reducing the risk of electric shock. Even if you manage to find yourself soaking wet while wearing your heated socks, you’re not going to be electrocuted. Most heated socks that require an outlet for power or include rechargeable batteries also have a surge protection safety feature.

Q. Can heated socks catch fire if they get too hot?
If appropriately used, heated socks are not a fire risk. If you’re worried about fire safety, look for socks with an automatic shut-off mechanism to prevent the temperature from getting too high.

Q. I’m worried about exposure to electromagnetic fields (EMF). Do I need to worry about this with my heated socks?
Not at all. The low voltage doesn’t produce any EMF. Rest easy!

Q. I like the socks I already have. Is there a way to warm my feet without having to throw away my favorite socks?
Heated insoles can be used inside your boots or shoes in place of heated socks. They do tend to be more expensive than heated socks, however.

Q. Are heated socks appropriate for physically strenuous winter activities like running?
Not really. Unless you have severe circulation issues and your feet are cold all the time no matter what you’re doing, a pair of heated socks probably won’t be comfortable for running or other similarly taxing winter sports. Heated socks are a better choice for more sedentary outdoor activities like fishing or hunting.
