Constantly cold feet: a simple method of keeping warm even in severe frosts

There is a simple method that lets you stay warm even during severe frosts without resorting to bulky shoes. This army technique has been used for decades.

The basis of this method is ordinary aluminum foil, which can create a heat-reflecting layer in shoes, protecting the feet from the cold from below and keeping warm.

Why do feet get cold in winter?

The main reason is tight shoes. If boots or shoes fit tightly, blood circulation is reduced, and the natural air layer that warms the feet is lost. It is best to choose shoes half a size larger than your usual size to help retain heat.

Dryness is the key to comfort.

Another important condition is dry feet. Moisture quickly provokes cooling. Before going out into the cold, it is useful:

Use antiperspirant for feet.
Treat shoes with a water-repellent spray to protect against moisture and snow.
These simple habits can significantly increase comfort in the cold season.

How to use foil for heating

The foil can be placed under the insole of the shoe, as it reflects heat back to the feet and blocks cold from below.

Suitable for this:

kitchen aluminum foil;
heat-reflective foil (the effect will be even better).
Trace around the insole of the shoe and cut the foil to size.

Choose the right place for the foil.

The foil should always be placed under the insole, not on top. If you place it on the top layer, it can lead to condensation and cause your feet to sweat, reducing efficiency. For maximum warmth, you can replace the standard insole with a felt insole, which, in combination with the foil, retains heat well, providing comfort even in extreme cold.
