Merino wool insulated 3D insole designed for winter activities such as walking, skiing and snowboarding.
Anatomical 3D shape keeps feet in the correct position. Insulating ALU foil combined with merino wool prevents cold penetration and heat loss and effectively reduces odour. EVA material under the heel absorbs impact.

Why merino?
The defining characteristic of merino wool is its warmth, or rather its ability to retain heat even when damp. This is because merino wool is capable of absorbing moisture up to 30% of its volume (compared for example with polyester, this is many times more) without significantly affecting its thermal insulation properties. This prevents the unpleasant, chilling sensation when sweating. Another important factor is the antibacterial property of wool. Insoles made from merino wool therefore do not smell even with prolonged wear. During sports activities, merino provides a very comfortable surface, warmth and a feeling of cleanliness.
