DexShell Ultra Thin Modal Socks



Thin and comfortable, while remaining waterproof and breathable – these are very good weather-resistant socks

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.

As the name suggests, DexShell's Ultra Thin socks are refreshingly low-profile – feeling very much like a typical winter weight sock while proving to be robustly waterproof and breathable.

  • Pros: Thin, comfortable, breathable, fair price
  • Cons: None, really

When it comes to waterproof socks, there's really one question that needs answering: are they, or aren't they?

The good news is that the DexShells are genuinely waterproof – proven through a number of wet autumnal rides, as well as use while pursuing my other active hobby, rowing. Unless you go to the trouble of really grinding the sock into a deep puddle, for example, the waterproof 'Porelle' membrane really does remain an effective barrier, even after a few standard washes.

They're breathable too; impressively so. As with the last waterproof socks I tested from Showers Pass, I tended to wear trainer liners with the DexShells and found that they emerged noticeably drier than they had with the Showers Pass socks.

I think that's down to the thickness: the DexShells are definitely thinner – they're half the weight – and it meant my feet tended not to heat up and sweat as much, and means moisture can escape easier too. In deep winter I'd probably veer back to using the Showers Pass socks for the extra warmth, but for middling seasons there's no question which is more comfortable to wear. The internal bamboo-based fabric layer in the DexShells is softer, with the whole sock moulding to the curve of the foot and ankle better and – crucially – fitting better within the confines of my shoes. This also means circulation is improved, while the outer Modal-based fabric is resilient and sturdy, protecting the membrane.

Naturally, you'd expect to pay a fair amount for this effective performance, but the DexShells are among the cheapest that the brand makes at £22 a pair. That seems like fair value when you can spend a similar amount for a technical summer sock at times, and the Showers Pass are a fiver more.
