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.

Giro's HRC+ Merino Wool Socks will challenge everything you thought you knew about life or – failing that – keep your feet very comfy indeed. The seven-inch cuff and 70 per cent merino combine with a gently compressive fit for a sock that's warm and protective, yet never hot or sweaty. Breathable, well shaped and nicely detailed, the HRC+ does everything you want in a sock except, now I think of it, challenge everything you thought you knew about life.

The HRC+ has become my go-to riding sock. It's tight enough to stay exactly where you put it, yet never uncomfortable – the stretch from the non-merino bits (15 per cent polyester, 10 per cent Lycra, 5 per cent elastic) is very well judged. The cuff height is similarly well judged, and fits with all lengths of short without looking odd.

The sizing is accurate and merino's mythical, semi-magic properties mean it's comfy in a broad range of temperatures – I've worn this on days between 8°C and 30°C and stayed happy. It's also very good at resisting smells. After four long rides in a row without washing it, the HRC+ still had that new-sock smell. It wouldn't even stand up on its own. Seriously, why aren't all clothes made of this?

If you don't like this purple it comes in six colours: three bright (yellow, red or blue) and three dark (black, grey or this one). However, at £22 it's an expensive option. Ashmei's Classic Chequered merino sock is £18, for instance, while Kalf's Winter Merino is £15 and dhb's Aeron Light Weight Merino is just £10. (And of course you can buy non-merino Argyle socks for just £6.99.)

It you do invest, though, it's unlikely you'll regret it. The Giro HRC+ Merino Socks are as usable, comfortable and pleasing as cycling apparel gets.

Tell us what the product is for

Giro's UK distributor ZyroFisher says: "The HRc Team sock has become Giro's most-loved sock for riders who demand performance. It is now available with a core spun Meryl Merino wool yarn that adds the soft touch of wool for mountain biking and some warmth for cool-weather riding. The compressive qualities of the HRc+Merino wool sock promote increased circulation with greater arch support, and the extra-reinforced toe and heel improve durability. With a 7' cuff height, you have protection on the trail and warmth when the weather gets cool."

The socks are excellent, but bearing in mind the price I'd say overall they're very good. If they were £15 they'd get a 9.
