At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
The Galibier Fire Feet 2 socks are made from a mix of merino wool and acrylic. The thicknesses vary from sole to top, giving a warm sock for all but the coldest winter days while also helping to keep the fit close to that of a summer sock.
Merino wool makes up 42% of the sock, and is known for its warmth and ability to retain heat when wet. It's used in combination with acrylic in the base and surrounding the toes, which is where you want the warmth retained, while the upper part of the sock is a slightly thinner acrylic mix.
The socks are quite tall at 17cm and cover a good part of my shin, making a noticeable difference on chilly rides. I would prefer a slightly tighter cuff to hold them on the leg a little more securely, though for some it might be fine.
I have to say, I don't trend to suffer too badly with cold feet, and in these Galibiers I was comfortable without shoecovers or a winter-specific shoe down to higher single figure temperatures, and to around 2°C with a warm winter overshoe.
The lowest temperature I used the socks was -5°C according to my computer head unit, and my feet did feel cold, but I think that could be expected and is good for a fairly thin sock.
They are quite thin compared with lots of winter socks, with the benefit that they will fit far better into your normal cycling shoes than thick winter socks. The toe box is perhaps the only area where they are much thicker, but flat seams help, providing a comfortable fit without any pinch points.
Galibier says these socks are for cycling only, not running, and the wool does seem to fray on the sole more than other socks I have, including other merino wool pairs. This is despite Galibier saying they have an 'abrasion resistant' sole.
Even taking this into account, their price of under £10 still looks good compared with other merino wool socks. DeFeet's Woolie Boolies provide similar levels of warmth and are excellent but they cost £23, and Steve liked the Giro HRC+ Merino socks but they're £22. Both of those are made with 70% merino, though.
As warm autumn/winter socks, the Fire Feet 2s are a real hit, with the extra warmth being welcome without being overly thick, so they should fit in your normal shoes without your toes being squished.

Abrasion resistant sole.
Natural wool and Lycra®
Well made, with good seams.
Warm and comfortable down to very low temperatures, but also not too bulky, meaning I was able to keep using my usual cycling shoes without discomfort or feeling like my toes were cramped.
Early days, but I do have concerns about the wool on the sole fraying, which isn't something I have noticed with merino wool socks previously.
Perhaps a little on the large side if you are near the bottom of the recommended size. I found them just OK in length but would have preferred a tighter cuff to help hold the socks up when riding.
Warm, easy to put on and take off. No itching, no discomfort at all.
Excellent for a merino wool sock, with many brands offering similar at double the price (albeit with a higher percentage of merino).
How easy is the product to care for? How did it respond to being washed?
Fine, although you need to adhere to temperature guidelines as merino wool has a tendency to shrink. Washed at 30 degrees with no problems.
