Heated winter shoes. Heated insoles - which ones to choose? Review of heated insoles manufacturers

Forget about the eternal cold in winter! When going for a walk, fishing or hiking, you can simply insert heated insoles into your boots. During the day they will keep your feet warm and help you forget about discomfort. Meanwhile, you don’t need such insoles if you wear high-quality shoes from a manufacturer that has been pleasing its customers with reliable products and flexible prices for many years.

There is a lot of information on the World Wide Web about insoles that protect your feet from the cold. The advantage of these new products is the use of special orthopedic instep supports, and some of them include a control panel.

How does a heated insole work?

The insole is equipped with a heating pad placed in the hollow part. For several hours it effectively protects your feet from the cold. The insole is made of polypropylene material that retains the shape of the foot and evenly distributing heat. In stores today, there are two types of warming insoles: made of genuine leather and made of artificial suede. Its toe section has a perforated surface that helps keep your toes freely warm. The lower part is equipped with pressed channels that distribute warm air throughout the foot.

But not all heated insoles can clearly perform their functions: often the consumer pays for a low-quality product that does not at all meet his expectations. It turns out that the money is spent, but your feet continue to freeze. Therefore, in order not to make a mistake in choosing, let's get acquainted with TOP manufacturers insole for heated shoes and with the characteristics of this product.

With the products of this company, you are guaranteed a comfortable microclimate in your boots. Your thoughts are no longer occupied with the problem of heating your feet when walking. Despite the use of electricity, there are no wires in this model. The ThermaCELL device works as follows: it is inserted into the charger for 3 hours (the first charge is 6 hours), then placed in a boot or boot. The heated insole is powered by a lithium-ion battery that lasts for 5 hours. The total resource is 3000 hours per 500 recharges. The heating is turned on or off using remote controller a, which fits conveniently in your pocket. There are three heating modes and 5 size adjustment options.

The product of this British company can be cut to fit shoes of any size. Inside the insole there is a carbon plate that heated by infrared radiation to almost 46 degrees. The radiation helps improve blood circulation and distribute heat evenly throughout the foot. The heating element is located right under your fingers. The control unit for each insole is attached to the shin or to the outside of the shoe. As in the first option, the insole runs on batteries, and the heating is controlled by a switch on the power supply.

Another company produces high-quality heated insoles that perfectly keep your feet warm during skiing or a long walk. Modern DiClime models have no disadvantages. They are equipped with a built-in battery, which, thanks to its shape, can be discreetly attached to the ankle and does not interfere with walking. They work using infrared heating elements, which have a beneficial effect on the human body and support natural heat exchange. A special sensor allows you to save battery charge.

The advantage of products from this company is their ability to take on a physiological form, which the same instep support has. The heat from the device affecting the foot can even cure leg pain X. A powerful battery is built into the heel area, where there is an input for the charger and a button, when pressed, the insole begins to emit heat. The built-in microcircuit and thermoelement maintain a high temperature for a long time, and the device charges in 2 hours. 2 indicators show the battery charge level.

The heating area of ​​HeatFabric warming insoles is located under the toes that require the most heat. Like all other models, these insoles can also be cut along the marking lines to obtain the required size. The insoles of this company are made of dense EVA foam material: this is the basis softens the blows and at the same time provides a high level of comfort, and high-quality fabric on top provides an optimal microclimate for the foot. The heating element distributes heat evenly and continuously over the entire surface of the feet for almost 8 hours, providing comfortable heating V. The electric wire, which is located on the inside of the insole in the center, eliminates chafing of the feet.

How to make heated insoles with your own hands at home? After analyzing many articles and online stores that sell electric insoles, certain conclusions were drawn. Firstly, their price tag is inflated by a thousand to one and a half rubles, and this is not the limit.

Secondly, in such insoles there are four elements located at the toes that heat up during operation. Nothing special. People's reviews of such insoles are frustrating: people say that this is a kind of torture with cold and heat at the same time. Although the toes are warm, the heel is cold. The feeling is not very pleasant.

In order to make simple heated insoles with your own hands, you need to purchase the most common ironing coil on the market or a coil for electric hotplates (power - approximately 500 W). The cost of such a spiral generally does not exceed fifty to one hundred rubles.
Next, you should visit a car store and buy the usual two connectors and a stranded wire. These goods will cost you a maximum of fifty to sixty rubles. You will also need a cardboard box to cut out the insoles for your shoes.

Mark these cardboard insoles crosswise every centimeter and estimate the approximate length of nichrome spiral wire you will need. It will need to be placed on the insole. As a result, the resistance of such a wire should be about 20-30 Ohms.

Each of your insoles at 12-14V from a power source will subsequently draw an electrical current of approximately 0.5A, and this will allow the insoles to heat up to 35 degrees Celsius.

Next, you need to make cuts around the perimeter of each of your insoles in order to lay the nichrome wire. Unwind the spiral from the ballpoint pen and place this heating wire into the cuts you made. Measure the resistance of the wire to get 24 ohms.

Secure the ends of your wire with tape at the bottom of the insole and bring it up to the place where the instep of the foot is and there is space to place the contacts. Connect the ends of this nichrome wire to a copper wire using a contact connector. Secure the places of this connection with threads so that it does not tear out when tensioned. This structure must be closed or secured with paper masking tape.

At the ends of the copper wire, secure the contacts in the form of a plate (precisely the car contacts that you previously purchased) and insulate them with heat shrink or electrical tape. Install the “matching” parts of the car contacts on the wires that come from the power source.

Voila! The insoles themselves are already ready. Now you need to make wires with similar contacts at their ends. We stretch them along the legs of your trousers or jeans, starting from the waistband and right down to your boots. Connect them with insoles. We connect the power source to the contacts, which we attach to the belt - use a 12 V battery with a capacity of 1.2 Ah.

It can be carried in one of your jacket pockets. It lasts for 1 hour of uninterrupted and good operation at temperatures of even -5 degrees, as well as -15 degrees for half an hour maximum. Once the battery dies, the temperature of your insoles will drop dramatically. In this case, replace the battery with a new one or a spare one. You can also use a homemade 14 V unit, which will serve as both a battery and a charger.

So you and I have achieved the effect of warm feet! This is simply bliss for those who love comfort.

In conclusion, it must be said that inventing heated insoles with your own hands, as it turned out, couldn’t be easier. You will be proud and satisfied with such creativity, and your legs will thank you very much! These insoles can last for about 3-4 months. In total, it will take you a maximum of 1.5 hours to make these insoles.

Sometimes even high-quality shoes made from natural materials cannot protect us from low temperatures. During the winter season, frozen feet cause significant discomfort. And hypothermia of the body is a direct path to colds, kidney disease or other unpleasant ailments.

But leading companies and shoe manufacturers began to produce devices for additional insulation of their products. The most convenient and versatile item that protects our feet from severe frosts are heated insoles.

Types of models

This powerful barrier from the cold will not allow our feet to get cold even when people who have used heated insoles at least once have had only positive reviews. Fans of winter fishing, skiers and residents of cold regions especially need additional insulation of their feet.

• medium-sized metal staples;
• foil.

First, you need to cut out a template from cardboard according to the size of the wool insoles. It should be carefully stitched with wire around the entire perimeter. You need to leave a gap of about 1 cm between the lines of the spirals.

Sew the toe area of ​​the template more often than the heel area. Combine wool and cardboard insoles. Attach a layer of foil to the bottom side.

How to choose the right insoles?

If you're going hiking, ice fishing, or have long walks in the cold with a stroller, thermal insoles are a great way to forget about cold feet. But among the variety of models, it is difficult to make a choice, therefore, when purchasing these products, pay attention to the following nuances:

• Size. Since this item is intended for winter shoes, you should be prepared for the insole to be much wider than your foot. You need to choose either your product size, or an order of magnitude smaller. Some insoles can be cut and adjusted to fit the size of your shoes.
• Control. Take a closer look at models with a remote control. Thanks to this device, you can quickly turn off the insoles in the car, when entering the store, and start them up if necessary.
• Volume. Some types of heated insoles are much thicker than regular ones, so they can only be used in wide shoes.
• Time of use. If you're going on a long hike, make sure your insoles work smoothly. The best solution would be to choose a product that is recharged by batteries. During your stay in the cold, you just need to change them, enjoying the continuous warmth.
• For short walks, disposable insoles may be suitable. They should be thrown away after use.
• Availability of recharging. Some models provide a power connection to the car, which allows you to take care of the warmth of your feet even while on the road. This accessory can be purchased separately.

If you choose the right insoles, you won't be afraid of winter frosts.

Features of use

When finished using, be sure to unplug the insoles. The product must be stored in a special bag in a dry place. To charge, remove the insoles from the shoes and dry them.

There is no need to subject the product to heavy loads, bending or deformation. Doing so may damage the heating element.

One of the conditions for maintaining a stable temperature inside the shoes is the correct choice of socks. They should be of medium thickness and wick away moisture well.

During use, make sure that your feet do not get too hot. If the insoles are warm and you feel comfortable, there is no need to add temperature. In case of a sudden increase in heat, it is better to turn off the device and make sure it is working properly.

It is not advisable to use insoles during active sports or running. Excessive loads in the area of ​​the heating element can lead to its breakdown or malfunction of the device.

The insoles cannot be washed. It is best to dry them at room temperature.

Popularity of products

Residents of many countries have already tried heated insoles. Ukraine, Russia, Belarus are famous for their cold winters. A long stay in the cold can lead to hypothermia, various diseases and ailments.

Using thermal insoles, you don't have to worry about the comfort and warmth of your feet. Long waits for a bus at a bus stop, winter walks, fishing and hiking will take place in a good mood without fear for your health.

Consumers who have used heated insoles have had rave reviews. The products are very easy to use and have a long service life. The ability to reduce the size allows you to use insoles even for children, adjusting them to the child’s miniature foot.

In practice, the insoles have shown their reliability, practicality, durability and effective warming of the feet even in severe frosts.

A high-quality product, subject to simple rules of use, will serve you for several seasons, protecting your body from hypothermia and illness.

There are only three main groups of insoles on the market - chemical disposable insoles, wireless insoles with a battery built into the heel, and wired models with external batteries.

Let's look at the key properties of each model:

	Wireless heated insoles	Blazewear Wired Heated Insoles	Chemical heated insoles
Heating temperature	40 - 51 degrees (three modes controlled from the remote control)	40-51 degrees (three modes are controlled on the battery)	30-70 degrees (uncontrolled and unpredictable heating - from imperceptible to burning)
Continuous operation time	48 hours	up to 11 hours (7 hours from batteries + 4 hours from batteries)	3-7 hours
Ease of use	They have a significant thickening in the heel - only suitable for loose shoes (at least one size larger). Felt when walking.	No thicker than a regular insole, suitable for any shoes, incl. model. Can't be felt when walking	At first they are not felt in the shoes, the closer to the end of use, the more they turn to stone (unpleasant to step on)
Battery placement	The battery is located in the insole itself. The absence of wires is a plus, but under the heel the thickening reaches up to 5 centimeters (a large difference between the toe and heel)!	The battery is placed on the shin using special elastic bands. It doesn’t cause any inconvenience; after the second use you don’t notice it on your leg.	Absent
Exploitation	In order to prevent overheating of the battery, heating is carried out cyclically, intermittently. The cycles are not synchronized - the insoles may heat unevenly (one works, one doesn’t).	Heating occurs continuously, in accordance with the selected mode.	Constant heating, no way to turn it off or make it weaker/stronger
Control	Remote control control. Pros - convenience. Cons - often does not work the first time, may not receive a signal in the city (interference)	Battery control. Clear selection of modes accompanied by indication	No management

Life time	Not intended for daily use, only for one-time events	Limited by the life of batteries, which are subsequently replaced	Disposable, have a short shelf life
Durability	It really depends on the shoes. They are critically susceptible to bending, which can lead to breakage after 3-4 uses.	Minimum 3 seasons. Tested by thousands of satisfied customers in Russia and Europe.	1 time (3-7 hours)
Safety	If the battery protective casing is deformed (for example, due to a strong impact or jumping on it), an explosion and fire may occur.	The battery is placed on the shin. In wired insoles you can safely walk, run, jump, get your feet wet - nothing will happen to it. Safe even for children!	If you use low-quality chemical insoles, you may get burned.
Price	From 5,000 rub. Option with a replaceable battery - from 10,000 rubles.	RUB 1,795 - basic version 4495 rub. - option with replaceable batteries	From 40 rub.

Comments on key differences:

• Convenience. Wireless electric insoles have a significant thickening in the heel (where the battery is located). It is unlikely that it will be possible to place such insoles in your usual shoes. You will have to use either shapeless felt boots or buy sports shoes a size larger.
  The thickness of the wired insole does not exceed the thickness of a regular one. It can be placed in any shoes (including dress shoes). The remote battery can be discreetly placed on the shin or hidden in the boot. You can also use extension cables to put the battery away, for example in a jacket pocket.
• Usage. Wireless heated insoles are not intended for daily use - in a word, you cannot go out for a walk or work in them every day. They are great for “one-time” activities (hunting, fishing, hiking), but with daily use their service life will be extremely short.
  The service life of wired insoles is limited solely by the service life of the batteries used, which are then easily replaced. The thermal insoles themselves from the British company Blazewear are very durable and reliable.
• Safety. Inside the wireless heated insoles there is a lithium-ion battery, and if the protective casing is deformed (for example, due to a strong impact or jumping on it), an explosion and fire may occur!
  Wired insoles are absolutely safe to use - even children use them. The battery is placed on the shin. You can safely walk, run, jump, get your feet wet in the insoles - nothing will happen to it.
• Heating temperature and duration. If in terms of heating temperature the compared models are quite comparable (about 51 degrees at maximum), then in terms of operating time it is much more profitable to use wired insoles with a remote battery. After all, to the battery life, a “reserve” resource is also added in the form of a block for AA batteries. That is, when going for a long walk, you can take a set of batteries and an extra set of batteries with you, just in case.

The comparative analysis was carried out on the basis of statistical data on sales of all listed models of heated insoles.
Based on the above factors, to maintain a warm foot temperature during the cold period, we definitely recommend using
