The S-KARP Omu FXT mountain boots are equipped with a plastic heel designed for gripping crampons with semi-mechanical grip. The exterior is made of hydrophobic natural leather with a thickness of 2.2 – 2.6 mm and a Vibram Foura Micro sole. It is complemented by a rubber overshoe that protects the foot and the skin of the boot on rough terrain, while also increasing water resistance. The interior is lined with a special eVent membrane, which provides the foot with very good thermal comfort even in frosty winter conditions. The membrane quickly absorbs moisture and keeps the foot dry regardless of the level of effort.
