The inside of these business socks consists of thermo-regulating Outlast®, a high-tech functional fiber: Outlast® warms when cold and cools when warm. Super elastic Micro Lycra® as intermediate layer guarantees a perfect fit and the necessary elasticity. The outside is made of highly resistant Fil d'Ecosse pure cotton thread which makes these socks extremely durable.
The tip is hand-linked and thus pressure-free. For a better distinction of the pair, the socks have a blue color marking.
