    Perfect for over the timberline trekking


    I bought my first pair of Thorlo Mountaineering Socks close to 30 years ago and I'm happy to say the quality has stayed the same. In a time when most of our favorite brands have all gone downhill, Thorla continues to provide top quality socks. When I first started hiking I took a long time looking for a good hiking boot but didn't pay much attention to the socks. After complaining about blisters and sore feet someone recommended Thorlos so I (skeptically) gave them a try. I never wore another brand of hiking socks again. They really do deliver what they promise. If you want to actually get what you pay for then try these. They do not disappoint.

    Too Short!


    I sat down to request an improvement by Thorlos, but before that I decided to read the reviews and see if anyone else had the same complaint. Danged if David D. didn't have the exact suggestion that I have: Increase the length of the sock about 1.5 inches. They are not true "over-the-calf" socks, so the fit, comfort and stay-up-on-your-leg-all-dayability is compromised. And don't think David's height is the problem -- I'm 2 inches shorter (5'-11") with 2 inches less inseam (34") than David, and the socks are too short for me, too. Hopefully the folks at Thorlos read these reviews and correct this one flaw in the product. I've been wearing the Thorlos Trekker socks for many years -- all day, every day. Weddings, funerals and church are about the only events that keep the Trekkers in the drawer. Even though the yarn mix in the Mountaineering socks is a bit different than the Trekkers (more wool in the long socks), they're pretty close. Just wish the Mountaineer was longer.

    Best socks for work


    My son says these are the best. I buy them for him. He is on his feet all day and outdoors as well. He always complained about extreme pain in his feet. I bought him every brand sold. He tried them all. He only wants Thorlo's.

    Warm and comfortable


    Best winter socks I've worn. Thorlo's buy 3 get 1 free is just icing on the cake. If you do a lot of outdoor activities in colder climates, these socks will fit the bill.

    I use these socks for evenings at home - they provide relief to tired aching feet and ankles that I never imagined possible. I recomended them to a friend who is a profesional Chef and on his feet all day, and they are a new lease on life for him. Highly recomended, and not just for hiking ! !

    make bad boots fit well and help my mother with her leg spasms


    I love these socks for their cushioning properties. They make my leather boots feel broken in. I put a pair of silk socks underneath them to totally remove all friction as I walk. My mother is 80 and she has frequent leg spasms. The warmth of these socks helps her greatly. Their cushioning helps her as well. I love your socks and have given them to my friends already as gifts.

    Great product


    The mountaineering socks (same as hunting socks) are warm, comfortable, and they do stay up in place all day.

    Socks mania


    Will continue to use these for my busy days where I work on my feet and walk a lot. Flexible, cushioned and plenty of support while keeping feet dry despite their thickness and cushion in points of stress.
