This warms your feet more than a warmer and is free

By Vitia

With winter approaching, keeping your feet warm can be quite a challenge. While warmers are a common choice, there is a surprisingly effective and completely free method to keep your feet warm even in extreme temperatures.

In this article, you’ll discover a simple trick using an everyday object that usually ends up in the trash. If you want to see how to do this trick, watch the following that will show you how to do it.

The Tetrapak Trick

When we consume milk or juice, we tend to throw the empty tetrapak in the trash without thinking about its potential reuse. However, this material can be an excellent thermal insulator to keep your feet warm.

How to Create Thermal Stencils with Tetrapak

  1. Cut out and open the tetrapak: Be sure to clean it thoroughly if it’s dirty inside.
  2. Cut the tetrapak into two parts: Once opened and cleaned, cut the tetrapak in half.
  3. Draw the shape of the template: Place your shoe insole on the tetrapak and draw its outline.
  4. Cut out the tetrapak template: Using scissors, cut out the shape you drew.
  5. Insert the insole into your shoe: Place the tetrapak insole with the aluminum part facing up inside your shoe, under the original insole.

Benefits of tetrapak insoles

These homemade insoles will not only retain the heat of your feet, but will also prevent the cold from penetrating from the sole. In addition, they are extremely useful for shoes with thin soles, providing additional insulation that will allow you to stand on cold surfaces without feeling the cold.

This simple trick is not only effective, but also economical and eco-friendly. Instead of throwing away tetrapaks, reuse them to create thermal insoles that will keep your feet warm all winter long. Share this tip with your friends and help them keep their feet warm for free!
