Winter Socks EKOI Perf Thermolite Carbon Fiber 18cm
The extreme cold model of the range
These Ekoï winter socks have been specially designed to tackle the freezing temperatures experienced while cycling.
The hollow fibre Thermolite®, universally recognised in the skiing world for its protection against extreme cold, has the unique ability to retain the foot's warmth. The carbon thread has exceptional insulating properties, providing excellent foot support and durability superior to most materials.
The new EKOI CARBON FIBRE winter cycling socks are made in Italy and have been specifically designed for cyclists (though they cna be worn for all sports). Available in 3 cuff heights: standard, high or very high.
The hollow THERMOLITE fibre is very popular with skiers in extremely cold temperatures as the fibe stores the foot's heat. The carbon fibre adds support and is hard-wearing, its thermal properties will protect you even in extremely low temperatures -10°C/14°F.
The "+" of these socks
- THERMOLITE hollow fibre creates an insulating air layer between the fabric and the skin, thus preserving the warmth of the foot.
- Specifically finer weave on the top of the foot to not interfere with the shoe tightening.
- Double and reinforced weaving on the sole of the foot in contact with the insole, which is more exposed to the cold.
- Anti-bacterial treatment.
- 3 heights: classic (bottom of the calf), high (mid-calf), and very high (covers the entire calf and reaches under the knee).
- The hollow THERMOLITE fibre creates a layer of insulating air between the material and the skin, thereby retaining the natural heat of the foot.
- Specific fine weave on the sock upper enabling trouble-free shoe tightening.
- Double weft reinforced weave for the footbed in contact with the shoe sole and which is normally the area of the foot most exposed to the cold
- Anti-bacteria treatment for odour-free cycling.
- 3 heights: standard (bottom of calf), high (mid-calf) and very high (to just below the knee).

These are great socks for cold chilly mornings, they keep my feet nice and warm and I don't even need to wear toe covers most of the time with them.

John T. 14/11/2025 Age: 45-54 Level: Advanced Convenient: Gravel, RoadThe perfect socks to keep you warm
These socks are the perfect solution to late fall and even winter riding as they keep you warm.
Sizing is accurate to size guide provided, and the socks work as advertised. I have a couple pairs of merino wool socks and these work as well - if not better than those.
Paired with either the waterproof shoe covers or even the neoprene winter shoe covers and you have the answer to keeping dry AND warm.
Ten out of ten, can recommend. -

I haven't had a chance to try them yet, as it is currently summer here and 36 degrees Celsius plus. However, they look and feel great and I appreciate the video of how to put them on. I am sure they will live up to the standard of the other EKOI products I have bought.

David W. 02/02/2025 Age: 55-64 Level: Amateur Convenient: RoadThinner warm socks
These socks are about as warm as the thick will hiking socks I have, while being thin enough to leave some air space in my winter cycling boots. Makes for warm get without feeling stuffed into your shoes.

James G. 11/01/2025 Age: 65+ Level: Expert Convenient: RoadMust have
These socks, coupled with the EKOI Overshoes Perf ICE PROOF Neoprene 4mm, are not only a winning combination, but the best winter riding I have ever experienced. I used them in 20 degrees F for a 2-hour ride and they kept me warm and comfortable the whole time. Highly recommended.

Dujana A. 24/12/2024 Age: 65+ Level: Advanced Convenient: Gravel, RoadImpressive construction! field not yet tested
I am a 35 + year cyclist who prefers outdoor cycling in inclement weather over any indoor training equipment. It was with this in mind that I purchased the thermal socks along with the neoprene gloves and shoe covers. I am thoroughly impressed with the construction of each item. I have paid more for similar items from storied brands.
I am anxious to road test my purchase so I will be updating this post. -

Mchale A. 01/12/2024 Age: 18-24 Level: Advanced Convenient: RoadWarm feet for the first time in ages
I suffer from Chemotherapy induced peripheral neuropathy and normally from the calves down my feet freezing, even in summer! I wore the mid length version yesterday and my feet were the perfect temperature and the calves warm. Given that they were so comfortable and unsweaty I wore them again today before ordering a second pair.
