Say goodbye to cold feet with THERMOLITE® FAR INFRARED technology. Socks with this breakthrough fiber generate warmth you can feel. Read on to see how it works.

Increasingly, consumers are demanding more from their socks. They want performance benefits that help socks dry quickly, keep feet warm, and are light enough to keep them moving freely. In response, The LYCRA Company is launching new THERMOLITE® FAR INFRARED technology  to help knitters, brands and retailers meet the growing need for high-tech features in everyday socks.

How the technology works

THERMOLITE® FAR INFRARED technology uses lightweight hollow fibers embedded with permanent ceramic pigments to harness the body’s far infrared* energy to generate gentle warmth. In our independent wear test, feet wearing socks knitted with 50% THERMOLITE® FIR yarn showed as much as 1.5°C increase in temperature than those wearing 100% cotton socks.


The fiber structure also provides relief from sweaty feet. Socks dry by transporting moisture to the surface of the fabric where it evaporates three times quicker than cotton. In addition, consumers can say goodbye to thick socks and layering to keep their feet warm. This breakthrough technology enables you to create versatile, everyday socks that are lightweight and offer all-day comfort suitable for any activity.

Double the brand power

Socks knitted with our new THERMOLITE® FAR INFRARED technology are additionally enhanced by the mandatory use of LYCRA® fiber in the sock top and leg. This offers brands and retailers the opportunity to drive sales by harnessing the power of two highly regarded brands.
