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.

These GripGrab Merino-Lined Waterproof Winter Socks have no problem keeping the elements out. They are amazingly waterproof, and not overly bulky with it, plus they do an impressive job of keeping your feet warm too.

If you are not a fan of wet feet, then you need a pair of these GripGrab socks as literally nothing is getting through their layers.

They're made from a polyamide/elastane outer and a merino wool (45%), acrylic and elastane inner sandwiching a polyurethane membrane, and are very comfortable to wear.

With some waterproof socks I've worn, the materials slide against the membrane, which can feel odd, but you don't get any of that here. The GripGrabs feel just like a traditional pair of socks.

They aren't bulky, but their construction does make them a little thicker than standard socks so you'll need a bit of spare room in your shoes. This isn't something you normally allow for in road shoes, but if you own a specific pair of winter shoes or boots with a bit more room in them then these socks will fit fine.

The merino wool content on the inside helps the socks feel soft against the skin and warm too. Merino is famed for its insulation qualities and that is noticeable here. Get your feet soaked in cold water and you will barely feel the temperature change.

Breathability is okay; it's not a major issue for their intended winter use, but on warmer days your feet will sweat, and things can get a bit clammy – the downside of waterproofing.

The only downside to the GripGrabs being so waterproof is that if any water gets in over the top of the cuff, it's staying in there. If you ride using mudguards, or use waterproof trousers over the top covering the cuffs, this won't really be an issue, but it's worth bearing in mind.

I found them great for gravel rides where it wasn't necessarily raining but there was a lot of flooding, and I could walk or ride through most sections without getting my feet wet.

The overall quality is great. A reinforced heel and toe protect against wear, and there are no stray threads hanging off anywhere. There are seams, but none are positioned in a way that irritates.

They are a fair chunk pricier than some, though, such as Giro's Xnetic H20 socks at £39.99 and Showers Pass's Crosspoint Waterproof Wool socks, which are £37.

Price aside, though, I really can't fault them; in terms of performance, comfort and quality they're great.

I got some Bridgedale (my normal sock brand) winter waterproof socks before the holidays, leisure lake were doing them better than half price. Very warm, feel weird though, the days I have worn them it's been wet, but not the soaking I need for the real benefit. I will only wear them when very wet, or take them for a wet commute home. But so odd I'd prefer to get damp feet unless crazy rain.

With a deep irony, they take 2-3 days to get properly dry after washing.

Is there not an ickle bit of contradiction between merino wicking it away and a moisture barrier to stop it being wicked away?

Sriracha replied to mattw | 1 year ago

The merino wicks it away from your skin. It was never going to wick it any further than the merino itself, after that it has to evaporate. Since the thing which comes after the merino claims to be breathable, no worries.
