Warm without being bulky

At 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.

The Assos Assosoires Winter Socks deliver a warm pair of feet when the temperatures head into single figures. With minimal seams they are also very comfortable, but unfortunately the overall result doesn't last well.

Keeping your extremities happy can be the make or break a cold ride, and these socks strike a lovely balance of warmth and breathability. Between about 12°C and 5°C I found them absolutely great: warm enough to not feel the need for overshoes, but without ever overheating me.

Most winter socks use extra bulk to achieve more warmth, which gives you less wiggle room in your shoes. These ones, though, feel just like your summer socks.

The material is soft with a delightful mix of compression versus comfort, which creates a cosseting, kind of second skin feel to them, but without being restrictive in the toe department.

The cuff pressure isn't over the top either, so they stay up without feeling like they're clamping off your circulation. They're available in three sizes, covering a range from EUR 35 to 46, and sizing feels accurate.

The white strip that runs up the back is pretty cool. Assos calls it STL – Spot The Light – as it incorporates photoluminescent threads and basically glows in the dark.

The only problem I had was that I found these socks a little bit fragile around the heel. I've been wearing them two or three times a week for six weeks or so, and have already worn a small hole in one heel.

Not exactly what I'd expect at this price. Assos does offer a two-year warranty though, so if I'd bought them I'd be due a replacement.


We're talking £18.00 here. That's almost double the price of the Galibier Fire Feet 2 at £9.77, and while Matt did say they might not be the most durable, neither are the Assos.

dhb offers the Aeron Lab Winter Sock for £18 (currently £12), which Simon described as super comfortable and warm with minimal bulk.


These are comfortable, warm and offer a great fit then, but longevity could be an issue.

Tell us what the product is for

Assos says, "In cold weather, staying dry is imperative to staying warm, so we engineered a unique yarn that provides midweight insulation while transferring moisture like a summer sock, ensuring the added warmth isn't lost to clammy chill. We also added a strip of highly visible STL textile on the Achilles and a ring of Winter 3/3 blue around the arch, increasing your visibility on the road and your socks' visibility in a drawer of black cycling equipment."

Tell us some more about the technical aspects of the product?

Fabric: Cotton-wrapped elastomer provides soft, breathable insulation. STL (Spot the Light) incorporates photoluminescent threads to add light to your pedal stroke in low-light conditions.

Construction: 160-needle construction eliminates seams for frictionless fit that wraps in gently compressive support, preventing slumping or restrictive pinching at the cuff.

Engineering: Ribbed arch, a firm band circling the foot offers noticeable arch support.

I'm generallly a fan of Assos kit, but those sock are seethrough! I have a pair and the less said about their UK cold weather capabilities the better - though they are 2 years old and haven't worn through.   

Best Winter socks I have are Endura Thermolites... after 30 years of riding through Winter.

I totally agree with you on this, calling them winter socks is laughable, Damp Autumn would be more honest.
