Rated 5 out of 5 by from Excellent product Bought these socks for my son. These are his 2nd pair, 1st pair he wore out, he had had them for few years. He said he wouldn't go mtb without them. Keep his feet snug and dry.

Rated 4 out of 5 by from Waterproof I bought these online for Agility with my dog when I have to wear running shoes. Certainly do the job and are warm. I think I should have ordered the size up though (I’m usually a 38 so I got the size ending 38) as they don’t stretch like woolly socks. I think a bigger size may have fit better and not leave welts on my calves.

Rated 4 out of 5 by from Sock knee high and waterproof Not much more to say they work well. I little wide for my calves and fall down a bit when cycling. Otherwise keep my feet dry which was the main objective.

Rated 5 out of 5 by from Great for festivals Used for a 3 day festival, (had two pairs and swapped each day) kept my legs warm in the evening unlike normal long socks and most importantly dry. Very impressed, haven't tried washing them yet though. Im a size 5 and bought 6-8 which seemed to fit well. Would recommend.

Rated 4 out of 5 by from Very good protecting socks I am a long distance bike rider (from 200 to 1.200 km see BRM audax Parisien). We sometimes have to ride in rainy conditions and for a long time. I just used the socks I recently bought and again I am happy. About 4 hours in the rain but still comfortable.

Rated 5 out of 5 by from Great for autumn and spring rides These are good for autumn and spring rides in Finland. Sinces these are waterprrof and insulated you can use these with summer mtb shoes on those spring and autumn rides. Could have silicon band to better stay up.

Rated 4 out of 5 by from Excellent for Canoe Tripping! I bought these socks a month ago just to try them out and I absolutely fell in love. They're so useful for my job which involves walking through water everyday as well as portaging. They're so handy and useful, however since I do wear them everyday they wear out a bit quickly. (But they weren't designed to be use everyday so it makes sense!!)

Rated 5 out of 5 by from The ONLY sock for any distance, any weather. I have used Sealskinz socks for years. Still the best. No blisters, dry and comfy, and I am talking non-stop distances of up to 100 miles.

Rated 5 out of 5 by from Fantastic socks!! I bought these about a month ago to take on an iceout fishing/canoeing trip in Ontario Canada. Not only did these keep me dry during our 5-7 days of spring weather, they also kept my feet very warm. These will be coming with me on every canoeing trip where portaging through unknown ground cover is required. They fit a bit loose, but that worked well to put another thin pair of wool sock underneath.

Rated 2 out of 5 by from Not what I really wanted. I bought these socks hoping that they would do something that they were not guaranteed to do. I wanted to wear them in a swimming pool and hoped that they would keep my legs dry as I seem to have an allergic reaction to the chlorine in the pool water. They did not keep the water out at all. I tried a second time with elastic bands around the top of my legs. There was much less water inside the socks but my feet were still not dry. If I could figure out a way to stop the water coming into the top of the socks, they would possibly work just fine for my needs.

Rated 5 out of 5 by from Kept feet dry and warm Kept feet dry and warm on a very wet sailboat in early May - not an easy task!

Rated 5 out of 5 by from Comfortable and dry Have been training with them trying to get ready for upcoming sheep hunt. Have walked and climbed several miles in them very comfortable. Stood on the bathtub when I got them and yes my feet were dry. Exspensive but they do what they claim they will. I will pay for top quality. Don’t know about durability haven’t had them long enough yet.

Rated 4 out of 5 by from Good I used these with my Musto Ocean Racer boots. I found them to be a little bit sweaty, with Marino wool socks being a better wick of the moisture

Rated 5 out of 5 by from Dry comfort My repeat purchase of sealskinz socks. Having worn out my previous pairs I am trying out new mid knee socks thinking these go better with shorts than my old full length version. Still the same quality and performance as of old. After a day on the moors I can take of my boots and cool off my stockinged feet in a beck in the certainty of retaining dry feet inside my socks.

Rated 5 out of 5 by from Great for all your needs Bought these a month ago for a holiday hike around. Coastal walks can be great but even better if you can go in the sea. Spare pair on boots off and in you go.

Rated 5 out of 5 by from Dry Feet I bought these because I row on the Thames and there’s nothing worse than getting socking wet feet. These do exactly what they say! Perfect...

Rated 4 out of 5 by from Keep feet warm and dry We bought the knee high hiking socks for our trek in Nepal - in case of wet weather and trekking in snow. The socks kept our feet warm and dry over Thorong La pass (5419 metres)- hiking in snow.

Rated 5 out of 5 by from Kept feet dry and warm I tried for a hike in the Ouchita Mountains where we had 12 water crossings. They worked perfectly keeping my feet dry and warm. I wore a large and had a toe sock as a liner and this proved perfect for the conditions. You have to plan on wearing a larger size shoe if you do those because sealskins are thick. I was testing them for a future AT hike and will definitely be making them a part of my kit.

Rated 5 out of 5 by from MUST HAVE piece of kit I bought a pair a while back and they are genuinely incredible. I am an infantryman which means that I spend a decent amount of time in swamp areas and these socks saved my feet. Some of my friends would get trench foot from being too wet but my feet were always dry as long as I didn’t have water going over the knee level. They are also surprisingly breathable and your feet wont get sweaty. Note: I used them every day for 60 days (3x20 days with only 2 days in between each 20 day period) and they still function up to par

Rated 5 out of 5 by from Perfectly waterproof socks I bought these for my race on the Thames and they did not disappoint. They’re comfortable, fit well, and definitely waterproof. I got out into the river in water up to the top of my shins and my feet stayed dry!

Rated 4 out of 5 by from Did the job well! I have only used these once so far on a fairly cold day but through boggy ground and my feet stayed dry apart from me sweating. My feet were pretty warm too but the ultimate test will be running in wet snow for hours on end as I haven't found a sock that copes with that yet. It was a treat to take my socks off and have clean feet and legs compared to the usual mud between the toes. The only issue I have is the thickness of the sock makes it very hard to get shoes on - I just managed with my trail shoes but couldn't wear these with a fell shoe. They do stock thinner socks but I was told they weren't as warm (and my friend had some on and got very cold feet). I was worried I'd get blisters but after over 3 hours of running I seemed fine so it would be good to test them on a long day out in the fells. I have to say I only bought them as they were on a half price flash sale and wouldn't have tried them at the full price.

Rated 5 out of 5 by from Brilliant hiking socks I've been using Sealskinz hiking socks for the last 8 years. They are brilliant. Warm and waterproof. I would recommend washing them turned inside out and letting them drip dry (I destroyed my first pair by drying them in a machine - following the instructions on the socks).

Rated 5 out of 5 by from Waterproof socks. What a great idea! Bought these a few weeks ago and they have lived up to every expectation. Warm, comfortable and, above all, waterproof. Great product all round.
