Love these socks! Thick and warm. Stay up, but not too tight.Initially I got these for my husband for Christmas and he loved them. So this past week I got him 2 more pairs and I got me a couple and I ? be them too. It keeps our feet dry and warm and they r so comfy. It says u can put them in the dryer but I don't recommend that bc it ruins the elastic in the leg part and they start sliding down into ur boot. But other than that they r fantastic ???I was excited to get these wool socks just in time for the cold winter weather. They were priced very reasonably and had impressive reviews. However, after just one wash I noticed a long loose thread. Upon closer inspection, the inside of a couple of the socks have loose threads, and all of them have frayed inside seams. I have several older pairs of high quality wool socks. All the inside seams are clean and tightly sewn, unlike these. I don't expect them to last even a single season. I gave them three stars in an effort to be fair, since I just got them. If they last at least a couple of years like most of my other wool socks, I will add a star. If they fall apart in a couple of months, like I expect might happen, I will reduce it to 1 star. I am hoping I get at least one season out of them, and they don't end up being a total waste of money.***Update***Well I did get one full season of use out of these, and they appear to be holding up as I pull them out for a second season of use. Despite their drawbacks, I must say that they are so comfortable that they have become my favorite wool socks. For both of these reasons, I have decided to upgrade my rating to four stars****2nd Update****After two seasons of use they are starting to wear out. A couple of socks have developed large holes in the heels. Still, considering that my work and lifestyle are hard on socks, they have held up well. I did have one pair of REI crew style wool socks that held up for ten or so years, but unfortunately, they don't seem to be available anymore.Extremely comfortable and warm. My toe poked through one of the socks with the very first wear. Overall they’re comfy and cheap enough that I’ll probly just buy more to replace them, or invest in equally comfy socks that last.These socks are really comfortable. Seem to be warm but the temp here has only gotten down to 6°F. And we'll see about durability after a year of use.I purchased these because I was going to Indiana and first part of December and of course it's cold in Indiana this time of the year.Then ame back to California where I'm a maintenance worker on the freeway, so I use the socks now to keep me comfortabñe in my steel toe boots , and to keep me warm when its a cold day. Man ! These are by far the best work socks in the world. durable quality! I will buy him again and again and again.KI bought two different socks from this manufacturer. These and their "Thermal Socks for Men, Thick Warm Cold Weather Heated Socks for Winter", made mostly of acrylic.The softness is very similar. These seem less warm than the others which may be good if your feet sweat.These are less padded and have a tighter fit on foot. Those are my only two complaints.very easy to put on , these socks...warm enough that i sweat them up and wear a different pair numerous times throughout the day...wear them so much its hard to say how durable they are...slight hoes in the heels are forming
