Alutherm lambskin insoles - And the frost does not become a frustration For all those who have to work outside even at low temperatures (and of course for those who love to be outdoors at that time), shoe insoles made of Alutherm lambskin are recommended. With these insoles, we combine the advantages of pure sheep's wool with the insulating properties of Alutherm. Shoe insoles for harsh winter days Trudging through the snow for hours, whizzing down snow-covered slopes with the children on a sled or training as a ranger even in winter, there are many good reasons to spend as much time outdoors as possible even in the cold season. However, many are deterred by this, as they literally get cold feet. Here you can only learn from professionals. After all, anyone who has to walk or stand outdoors a lot every day at work knows from experience how to keep feet warm: with warm insoles made of lambskin. With our Alutherm Lammfellll shoe soles, we even put a layer on top. Literally! Because we have provided the underside of our shoe insole with an insulating layer of Altutherm. As a result, the cold does not even have a chance to penetrate your feet.
