Oslo Nordic Boot Sock is a lightweight, technical ski sock developed for long days on skis and comfortable travel in winter terrain. The sock is designed to provide a precise and comfortable fit in cross-country ski boots, winter boots and snow boots, with extra cushioning around the toes and two crossing padding zones over the instep that offer support without reducing sensitivity in the shoe.

The material is made with merino wool, which naturally regulates temperature and efficiently transports moisture away from the skin. This helps keep feet warm and dry, even over many kilometres. The lightweight construction balances good breathability with stable temperature regulation, so that comfort is maintained throughout the day. Ventilating mesh panels provide additional airflow when exertion increases.

A reinforced cushion around the Achilles tendon reduces heel lift and increases both comfort and durability over time. The toe seam is closed with True Seamless™ technology, delivering a very smooth and almost imperceptible feel with no chafing. The sock has a performance-oriented fit that stays securely on the foot without slipping or bunching during use.
