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.
Good scores are more common than bad, because fortunately good products are more common than bad.
The dhb Aeron Lightweight Merino Sock is the thinnest in dhb's three-option range, but it's still pretty warm, relatively thick and extremely comfortable. Sizing and fit are great, and those muted colours look good if matched with other dhb kit, though the super-messy stitching inside isn't impressive.
Testing these in cool, wet, autumnal conditions puts them a little out of their comfort zone, but inside shoes with toe covers they did well in temperatures between 6 and 10°C (the Mid or Winter weights might be better options as things get colder).
The sizing is spot on, the fabric has just the right amount of stretch for security without any restriction, and the padded footbed stays comfy for hours. They're pretty warm for a short and skinny sock, too.
That stretch comes from the 35 per cent that isn't merino, but is instead a mix of – according to dhb – elastane, Lycra and nylon.
The nylon part reinforces the heel and toe, while the toebox is seamless and there's a mesh panel over your instep. None of it's particularly thin – you can certainly find lighter-weight options for high summer – but it breathes well in mild and humid conditions.
For the sake of science (science, I tell you!) I wore these repeatedly without washing them, and they took it without developing so much as a whiff. Useful if you're riding multiple days, and it fits with the claims of a naturally anti-microbial nature for merino wool.
Actual washing they seem less happy with, rapidly developing bobbles along the footbed seams and tiny pulls in the fabric under the ball of the foot. These may settle down with further use, but it leaves a question mark over durability that the huge mess of exposed threads inside don't do anything to assuage.
These threads don't affect comfort and, again, the sock may shed a bit initially and be fine for ever after. To be clear, the seams remain absolutely intact after around 150 miles.
Although the colours and designs will be a little muted for some tastes, they come alive when paired with matching dhb kit. It's a shame there aren't a few wilder options for non-brand loyalists, though.
Price-wise, at RRP they sit alongside plenty of others, such as Lusso's SoftAirs, the Teko Adrenalins or Saikel Chevrons. However, if you must have merino then the Aerons are still a great bet, especially as they're rarely if ever sold at RRP – Wiggle was punting these out at £6 at the time of writing.
While there's a question mark over exactly how well the dhb Aeron Lightweight Merino Sock will last, in all other respects it's a good, warm, comfortable item that performs well and comes at a good price.
Warm, comfortable and low-key socks that wick well and resist smells, but inner stitching is a bit messy

A tenner isn't cheap for a pair of socks, and these are starting to show signs of wear already, but they're always likely to be discounted – currently to £6. You can also pay a lot more (dhb's own Aeron Lab Winter socks are £18).

Use this box to explain your overall score
The scruffy stitching and early fabric bobbling doesn't bode well, but then it might settle down and cause no real issues. Either way, the solid performance justifies a 7 – without the stitching issue they'd be an 8.
