Frequently Asked Questions
When should I choose 5.0 expedition cushioning?
The 5.0 expedition cushioning is specifically designed for extreme cold conditions below -5°C, high-altitude mountaineering, Arctic expeditions, and situations requiring maximum warmth and insulation. Choose this level when you'll be exposed to extreme cold for extended periods, using heavy mountaineering boots, or when equipment failure could be life-threatening.Â
Why is over-the-calf height essential for expeditions?
The over-the-calf (knee-high) design is critical for extreme cold conditions as it provides complete coverage inside heavy mountaineering boots. This height prevents dangerous gaps where cold air and snow can enter, which is essential when temperatures drop to extreme levels. Professional mountain guides and expedition mountaineers rely on this height for multi-day trips where every detail of cold weather protection matters.
Are these socks suitable for everyday winter wear?
The eco EXPEDITION 5.0 socks are engineered specifically for extreme cold conditions and expedition use—they may be too warm and bulky for everyday winter activities. For regular winter hiking, walking, or daily wear in cold weather, we recommend the eco HIKE TREK 4.0 with heavy cushioning or the eco HIKE HIKING 3.0 for moderate winter conditions. The expedition socks excel when maximum warmth and protection are essential for survival.
What makes these socks suitable for professional expedition use?
The eco EXPEDITION 5.0 combines maximum cushioning with Bluesign® certified merino wool, reinforced high-wear zones, and over-the-calf height for complete protection. The merino wool construction provides enhanced durability for extended expeditions whilst maintaining natural moisture management critical in extreme cold. Manufactured in Italy using renewable energy and backed by our lifetime guarantee, these socks represent the pinnacle of TEKO's technical sock development—trusted by professional mountain guides and serious mountaineers who venture into the world's most extreme environments.
How should I care for expedition merino wool socks?
Wash your TEKO eco EXPEDITION socks at 30°C (machine or hand wash) to maintain fabric integrity whilst saving energy. Always air dry—avoid tumble dryers as heat can damage the merino fibres and reduce the sock's insulation properties. Do not use bleach, iron, or dry clean.Â
