Frequently Asked Questions
What makes the 4.0 heavy cushioning ideal for winter hiking?
The heavy full cushioning 4.0 level in the TEKO ecoTREK provides maximum warmth and comfort for cold weather conditions. The substantial padding throughout delivers superior insulation from cold ground, excellent cushioning for long winter days, and fills space perfectly in heavy mountaineering boots. This cushioning level is specifically designed for those who prefer maximum comfort, suffer from cold feet, or spend extended periods in harsh winter environments across the UK's mountain regions.
Why is mulesing-free merino wool important?
Mulesing-free merino wool ensures that the wool comes from sheep that have not been subjected to mulesing—a controversial surgical procedure performed without anaesthesia. TEKO's commitment to mulesing-free wool reflects our dedication to ethical animal welfare whilst maintaining the exceptional performance characteristics of merino. All our merino wool is also processed using chlorine-free methods to Bluesign® standards, ensuring the highest environmental and safety credentials throughout the entire production chain.
Can I wear these socks in autumn or spring?
Whilst the ecoTREK 4.0 is optimised for winter conditions, the natural temperature regulation of merino wool makes these socks suitable for cold autumn and spring days as well. If you find standard 3.0 medium cushioning insufficient during shoulder seasons, or if you always prefer maximum cushioning regardless of season, the 4.0 level will serve you well. For most three-season hiking, consider our Exodus or Hiking 3.0 socks, but if warmth and cushioning are priorities, the ecoTREK delivers year-round performance.
How do these compare to the 3.0 medium cushioning socks?
The 4.0 heavy cushioning provides noticeably more padding than our popular 3.0 medium level. The ecoTREK offers superior warmth for cold conditions, maximum cushioning for all-day comfort, and works best with heavy mountaineering or wellington boots that have extra room. The 3.0 level (Exodus, Hiking) provides excellent all-season versatility and fits most standard hiking boots, whilst the 4.0 level is specifically designed for winter use, cold sensitivity, and those who simply prefer plush comfort.Â
How should I care for my heavy cushion merino wool socks?
Wash your TEKO ecoTREK socks at 30°C (machine or hand wash) to save energy whilst maintaining fabric integrity and the cushioning structure. Always air dry—avoid tumble dryers to save energy. Heat can damage merino fibres and affect the cushioning, reducing sock longevity and performance. Do not use bleach, iron, or dry clean. This gentle care extends the life of your socks, maintains the heavy cushioning properties, and supports their environmental credentials. The chlorine-free merino wool treatment means these socks maintain softness and performance even after many washes.
