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 DeFeet Evo Disruptor socks are comfortable, breathable and very tall. While it's impossible for us to verify the claims aero savings, they're certainly compressive and well made. They probably look better than your shaved legs too, but wow, you're paying for the privilege.
The DeFeet Evo Disruptor socks make a lot of aero claims, including that a 'rider at the 0°& 5° yaw indicated an average reduction of eight watts when compared to standard bare shaved legs and outperformed other aero socks available in the road cycling market'.
Unfortunately the road.cc wind tunnel is having new carpet fitted and my personal facility only measures from 6° yaw, so I can neither confirm nor deny this.
What is obvious about the aero design is how high they rise – eight inches above the shoe line, which is only slightly shorter than football socks. They offer compression all the way up too, which is good for performance over time.
DeFeet has also added compression and support around the foot, to help with comfort on long rides, and used minimal stitching on the toe box to reduce irritation.
At £29.99, these are very expensive, even if the 8W saving is achievable in the real world. Their compressive nature and long-ride comfort are good, so they may be worth the investment on that basis, but even so they're hard to recommend when so many other options are far cheaper.
The Giro HRC+ merino socks are probably the closest for fair weather at £21.99, and they're lovely. Meanwhile, the M20 Merino Crew Compression Socks are also very comfortable, seamlessly constructed and £16.99. They're both several inches shorter than the Disruptor, though.
The DeFeet Evo Disruptor socks are well made, comfortable and usefully compressive all the way up to their unusually high cuffs. They may even make you go faster... perhaps your own wind tunnel will let you know?
Comfortable, very tall and usefully compressive, but extremely expensive

Reinforcement on the heel and sole means they're likely to last a long time.
The material is soft and the lack of seams reduces the chances of chafing.

They are expensive.
How does the price compare to that of similar products in the market, including ones recently tested on road.cc?
They're expensive! The Giro HRC+ are probably the closest for fair weather socks at £22, and they're merino yet a full £8 cheaper.

Would you consider buying the product? Maybe
Would you recommend the product to a friend? Maybe
Use this box to explain your overall score
These are comfortable, well made and promise to make you faster, but the latter claim is unverifiable and the price is even higher than the cuffs. They're great to wear, but almost twice the price of some very good socks, leaving them just good overall.
