Prendas Ciclismo High Summer Dryarn-Resistex Carbon Socks



Lightweight socks for keeping your feet cool and comfortable on hot rides

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.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

The new Prendas High Summer Dryarn-Resistex Carbon socks – that's a bit of a mouthful, isn't it? – are a lightweight and cool choice for summer riding.

The section on top of your foot is a synthetic mesh (the socks are a mix of nylon, polypropylene, Lycra and carbon fibre). If you have mesh sections on your shoe uppers too you can feel the air coming right in to keep your feet cool.

The soles, the toes and the heel sections are thicker and there's a band around your midfoot that's more tightly elasticated to hold the socks in place – although I can't say that I ever have any trouble with socks moving about when I cycle anyway. The top section, above the ankle, is a double-thickness cuff.

The carbon fibre comes in the Resistex yarn – there's just a small amount in there. The idea is that the Resistex speeds up the evaporation of sweat and protects the skin from bacteria (it's bacteriostatic, meaning that it stops bacteria from reproducing).

I couldn't tell you for sure what the bacteria are up to on these socks – my eyesight isn't that good – but I can do a quick sniff test because I'm just back from an hour's ride in these – 21mph and 21°C, so a bit sweaty. Wish me luck...

Okay, they don't smell too bad at all, actually. I mean, I wouldn't put them back in the drawer, obviously, but they're far from minging. Perfectly acceptable, I'd say. I'm not sure that proves a great deal other than that I do some strange things for, but there it is.

Probably more significant is that these do feel really cool in use. Prendas Ciclismo's Coolmax socks are cool but these are considerably cooler. They wick perspiration away from your feet very well too and dry quickly.

Like I said, I'm just back from a ride and they got a little damp with sweat but they dried out very fast. They're intended for 20°C plus and that's about right for me although, of course, you can wear them when it's not so hot if you tend to overheat more easily.

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

Prendas say, "We are delighted to announce the availability of the latest addition to our comprehensive and now complete cycling sock range.

"These lightweight socks have been specifically designed for use in hotter temperatures thanks to their construction (mesh front being the most important elements) and the combination of different yarns in the weave to give you the best possible comfort and performance.

"The "Carbon" element is supplied by Resistex which gives the sock many extra properties including additional durability and optimum anti-bacterial protection.

"The nominal temperature range for these socks is over 20 degrees Celsius (68 degrees Fahrenheit), but of course some people run hot and some cold. So it's up to you!


* Lightweight

* Made in Italy

* Excellent wicking Fabric

* Reinforced toe and heel area

* Anatomical Cut

* Subtle Prendas Logo

* Great on hot summer days!"

That all sounds pretty reasonable.

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

One of the benefits listed by the Resistex manufacturers is that 'Resistex is high performing because during physical activity it lowers the concentration of lactic acid, improving the circulation of the blood and oxygenates the cells."

Right, I'm going to go out on a limb here and say that wearing these socks will not improve the oxygenation of your cells to any significant degree. They're good socks... but not for that reason.
