SealSkinz Mid Weight Mid Length Socks



Useful extra weaponry in the fight for warm, dry feet this winter

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.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

Sealskinz Mid Weight Mid Length Socks are a good thing to have in the drawer once the cold and wet weather draws in. There are some UK conditions that will breach any foot fortifications, but these socks are a great last line of defence.

SealSkinz use a waterproof membrane in between inner and outer layers. In these socks the inner is a Merino mix, and the outer synthetic. They're totally waterproof, as SealSkinz are wont to demonstrate at trade shows by having an unlucky employee stand in a giant petri dish for the amusement of onlookers. They work though. Water doesn't get through. You can go out in the rain in these socks and trudge about on the lawn and your feet will stay toasty and dry.

The membrane stops the socks being anywhere near stretchy as normal socks, and there are two layers of fabric. That means two things. Firstly, it's important to get the right size. Specifically, make sure they're big enough because they can feel very constrictive if they're too small. Sizing information is available on the SealSkinz website. Secondly, there's more bulk than a normal sock. If your shoes are tight with your summer socks on, you may struggle to get them on wearing these.

Assuming that's all good, go out and ride in the rain and your feet will be dry even if your shoes are sopping wet. Well, up to a point. These socks suffer from the same Achilles heel that all fully waterproof footwear does: once water gets in – and there's a hole at the top – it doesn't have anywhere to go, so it stays in there. The trick is to make sure no water gets down the neck of the sock if you want your feet to stay dry.

My favoured approach is to pair them up with overshoes and make sure they're tucked right inside with the overshoes as tight as possible at the cuff. If you're wearing longs you can pull them over the top of the socks, then the overshoes up over the longs, creating a sort of labrynthine seal which is normally good for a few hours even in heavy rain.

The two layers of fabric mean they're warm, and even when they do inevitably get damp inside on the wettest rides the Merino mix inner remains comfortable and cosy. They're completely windproof, too, which is often as much of a boon on really cold days as the extra insulation. Thinner and thicker versions are available to suit your particular needs. They're certainly a useful thing to have around for bad conditions. £30 isn't cheap, but they'll definitely get some use.

The photos make them look like the big toe is separate. Perfect for flip-flops!

These really need to be higher. Up to the waist would be a start.

The good thing about these socks is that the waterproof membrane is also very effective at keeping the wind out too.

When its properly wet, water will always run down the leg and inside - and as the review says it cannot escape.

However where these socks really come into their own is for those days where its a little bit chilly and/or a chance of rain - and you are trying to decide if it worth pulling on the overshoes or not - these make a fantastic alternative - so much easier to get on than an overshoe, less bulk, and they give that bit of extra protection.
