Sidas Winter 3D Merino insoles
Shoe insoles with merino wool for comfort and thermal comfort on cold days.
Merino wool insulated 3D insole intended for winter activities such as walking, skiing and snowboarding.
The anatomical 3D shape keeps the legs in the correct position. Insulating ALU-foil in combination with merino wool prevents the penetration of cold and the escape of heat and removes odors well. EVA material under the heel absorbs shocks.
Why merino?
The basic feature of merino wool is its warmth, or the ability to absorb heat even when it is wet. This is because merino wool is able to absorb moisture up to 30% of its volume (compared to, for example, polyester, it is many times more) without significantly affecting its thermal insulation properties. Thus, there is no unpleasant, cooling sensation when sweating. Another important factor is the antibacterial ability of wool. The insoles made of merino wool do not smell even after long-term wear. During sports activities, the merino surface provides very good comfort, warmth and a feeling of cleanliness.

![]() | "I've been using merino insoles for several seasons. They found a place both in downhill boots and in normal footwear during the winter. I also liked them for winter cycling, when when driving to work not exceeding about 40 minutes, my legs don't get so cold that I need overshoes. | I was afraid that the merino top would wear and tear quickly, but it doesn't. The material combines merino with synthetic materials, so even if a little more felt, it still holds up well in ski and cycling boots even after a considerable period of use." | Peter Havelka |
