Aerogel is a highly technical wonder material, which is super lightweight and has excellent thermal conductivity. It is used e.g. in astronaut suits. Aerogel keeps the cold away 3-6 times better than other insole materials. According to the manufacturer, its thermal conductivity is 0.015 W/m² both on its own and when you stand on it. Other insole materials are 0.030-0.050 W/m² on their own. When you stand on the other materials, most of the air is squeezed out, resulting in 0.045-0.90 W/m².
