Frequently Asked Questions
What does biodegradable mean for these socks?
Every fibre in the TEKO eco HIKE Bio.d — Merino Wool, Amni Soul Eco® Polyamide, and Tencel Lyocell — is certified biodegradable, meaning at the end of their life these socks decompose naturally in commercial landfill conditions, returning to nature without leaving lasting environmental impact.
What is Amni Soul Eco® Polyamide?
Amni Soul Eco® Polyamide is a registered biodegradable nylon developed by Nilit. It provides the same structural durability and shape retention as conventional nylon, but is engineered to break down naturally in commercial landfill conditions — making it a genuine end-of-life solution rather than a greenwashing claim.
Are these socks covered by a guarantee?
Every pair of TEKO eco HIKE Bio.d socks is backed by the TEKO Lifetime Guarantee against manufacturing faults — ensuring long-term confidence in a sock built to last before it ever needs to biodegrade.
