Aero doesn't always mean comfortable, but it does here
Impressively comfortable
Excellent quality

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.

When you've gone aero everywhere else and it's only your feet left, you're going to need a pair of socks co-developed with an aerodynamic specialist... and that is what you have here with the Le Col x McLaren Project Aero Socks. They're impressively comfortable and excellent quality – as you'd hope for the price.

In collaboration with McLaren, of Formula One fame, Le Col has developed a whole aero collection which incorporates a speedsuit in long (£375) or short sleeve (£350), a short sleeve jersey (£170) and a long sleeve jersey for £195. These socks are the finishing touch, for a mere £35.

What you've basically got here is a main foot section that's 100% knitted polyamide and feels like a traditional sock material, with terry padded sections for the toe and base, and an 82% polyester, 18% elastane blend for the lower leg section.

This upper section is basically similar to a lightweight overshoe that you'd likely find covering the shoes of most time-triallists; minimalist, with a virtual skin-like feeling. The stretch of the fabric and the silicone gripper at the top keep things in place.

The aero benefit? Well, for the majority of us it's not going to make the slightest bit of difference, but if you've covered every other base you can to remove drag then I suppose the theory makes sense.

I'm not here to belittle the effectiveness or the claims made – these socks are a tiny piece in what has been designed as a full aero clothing system – but I can't confirm them either.

> How to get more aero without spending a fortune

I did spend years riding time trials and while I was pretty drawn into the whole aero kit thing, spending a fortune on a skinsuits, helmets and so on, I was nowhere near the extreme level of some who were touching the podium, and I know for some riders these (very) marginal claims are important.

What I can confirm, though, is that these are very comfortable socks.

The foot section with that padding feels sumptuous in your shoe, while the lighter-weight sections are breathable and also create a very snug fit.

The material is soft to the touch, too, and all of the seams have been positioned out of the way. I could wear these things for hours.

The quality is exceptionally high as well.

As for the cost, while double the price of most 'normal' cycling socks, they aren't alone in being a little extravagant. Defeet charges £29.99 for its Evo Disruptor socks which it claims offer a watt reduction over bare shaved legs.


I can't quantify the aerodynamic gains, and they are going to be very marginal anyway, but I will say that these are some very comfortable and well-made socks. Whether that justifies 35 quid is up to you.

Aero gains are minimal for the money.

How does the price compare to that of similar products in the market, including ones recently tested on

The Defeet aero offering comes close, but most non-aero socks are half the price (or less) and can be just as comfortable.

Did you enjoy using the product? Yes, they are very comfortable.

Would you consider buying the product? No, the cost would outweigh any aero benefits.

Would you recommend the product to a friend? Yes, if they wanted a comfortable aero sock and price wasn't an issue.

Use this box to explain your overall score

Excellent quality and very comfortable, although the claimed gains wouldn't be enough for me to part with £35.

Overall rating: 7/10

As part of the Tech Hub here at F-At Digital, our senior product reviewer Stu uses the knowledge gained from putting well over a 1,000 products through their paces (including hundreds of bikes) to write in-depth reviews of a huge range of kit. After first throwing his leg over a race bike back in 2000, Stu's ridden more than 160,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him he still likes to smash the pedals rather than take things easy. Although, as he spends a fair bit of his time reviewing ebikes these days he's becoming an expert in letting the motor take the strain. He's also waiting for 23mm race tyres to make a comeback!
