Frequently Asked Questions

What cushioning level is best for year-round hiking?

The medium full cushioning 3.0 in the TEKO 9904 eco HIKING provides excellent all-season versatility for hiking and trekking. It offers substantial cushioning throughout the entire sock for comfort on long trails whilst maintaining breathability. This level works perfectly with hiking boots and provides protection without excessive bulk, making it ideal for use from cool spring mornings through winter adventures.

Why is 100% natural merino next to the skin important?

Having 100% natural merino wool directly against your skin maximises comfort and performance benefits. The pure merino provides superior moisture wicking to keep feet dry, excellent temperature regulation in both warm and cold conditions, and natural odour resistance that keeps socks fresher for longer. The durable nylon plaited on the outside enhances longevity without compromising the natural performance you feel against your foot.

What makes the Achilles Wrap System different?

The Achilles Wrap System is TEKO's proprietary knit technology that provides enhanced support and comfort around the ankle and Achilles tendon area. This specialised construction prevents the sock from sliding down during activity and reduces friction and the chance of blisters. Particularly important during long-distance hiking when every comfort detail matters. The enhanced fit ensures these socks stay securely in place from the first mile through challenging multi-day treks.

Are TEKO eco HIKE socks sustainable?

Yes, the 9904 features mulesing-free merino wool that's processed without chlorine to Bluesign® standards—the highest environmental certification for textiles. The socks are also OEKO-TEX® certified, meaning they're tested free from harmful substances. All TEKO socks are manufactured using renewable energy in Italy, and the lifetime guarantee encourages quality over quantity, reducing waste.

Can I wear these socks with Wellington boots?

Absolutely! The medium full cushioning 3.0 and crew height make the 9904 excellent for Wellington boot use. The substantial cushioning provides comfort during extended wear, whilst the natural merino wool manages moisture and prevents odour—particularly valuable in the warm environment inside wellies. The anatomical fit, Achilles Wrap System, and seamless toe construction prevent blisters during outdoor work, farming, or countryside walks.

How should I care for merino wool socks?

Wash your TEKO ecoHIKING 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.
