Ahma means wolverine in Finnish. This is the manufacturer’s top-of-the-line technical insole developed to meet the needs of active outdoorspeople in tough northern conditions. The form-fitted PU surface layer feels pleasant on your feet and allows the air to circulate very well. Inside the sturdy outer fabric, there is a 2 mm Aerogel insert. Furthermore, there is a reinforced reflecting aluminum layer at the bottom. They weigh. 45 g/piece (1.6 oz).

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.
