Rated 4 out of 5 by from Great socks, run larger to size Bought these socks as I love merino and love Smartwool socks. I have a few light and medium weight smartwool socks and I rate them highly.  These socks are very thick, very warm and are very cushioned meaning that walking is comfortable. I use them with a part of insulated snow boots.  My only critique would be the size. I bought these to wear as a single layer sock in my boots, I usually wear a size L Smartwool sock as my shoe size is right in the middle of the range (im a 43.5 - 44 Euro size). These socks run much larger and when I wear them alone, the heal tends to ride up the back of my foot. They do work well when I use a medium weight liner sock underneath them.  If you don't want to run a liner sock, I suggest you size down. If you do use a liner sock then order in your normal size.  The overall quality is very high.

Rated 5 out of 5 by from B.I.G. I can't fit comfortably in any of my regular footwear with this, so I mostly use it solo, as slippers. Oh, it'll fit, but the whole point of these socks is -to create air space- for insulation. If you -pack it in- then it won't function as -warm- as intended. I wear 11.5-12 in Mens shoes. I am an in between L-XL. I got these in XL and I can't fit comfortably in any of my regular shoes, from athletic (12) to boots (11.5). I do have an odd pair of size 12 boots I got because they were a good deal (and haven't parted with them), and these socks fit great in them. If you're going to use this for -warmth- in your boots, go 1/2 size up, with the boots, for proper fit and function.

Rated 5 out of 5 by from Amazing I bought my guy 3 pairs of these over a year ago for use in his work boots. He not only wore them all winter, but all summer too. Besides the fact that he loves the way they feel, even though these 3 pairs have been in heavy rotation for a year, they show very little wear.

Rated 5 out of 5 by from Absolute best sock ever I have used these socks winter mountaineering in the coldest,harshest conditions. I have used them on extended hunts and expeditions. These are the socks that have kept my feet the driest and the warmest over the past decade. Hands down the best for cold weather activities.

Rated 5 out of 5 by from Great socks These socks are soft, warm, and tall.  I wear them in the spring and fall when I am horse back riding.  I pull the socks over my silk long under ware so they do not ride up my leg.  The socks keep my feet warm all day.  My son and daughter in law work outside all day.  I have bought these socks for them also.  They love them too!

Rated 5 out of 5 by from Bad Circulation + Smartwool = No Problem I have poor circulation and find that my hands and feet are always freezing. Even in Arizona. In the summer. My last trip was with my fiance to Crater Lake, Oregon where we stomped around the snow in the ~30ish degree temps. My glove-less hands were freezing. But my feet? My feet were warm and cozy. So much so that I actually had to stop and comment about how warm I was in the chilly weather.

Rated 5 out of 5 by from Best hiking socks ever These are the comfiest and thickest socks I've ever owned. I've hiked the hills in sunshine, hail, rain and snow and they never disappoint. Love them.

Rated 5 out of 5 by from Make a sweater out of this material! Very thick, and warm. Perfect with boots on cold days, they keep your feet warm even when theyre wet. Also great worn indoors. Warm but you don't overheat in them. You forget youre even wearing them. What Smartwool should do is make a sweater/sweatshirt out of this same thick loopback knit material. It would be the most amazing sweater ever. Don't know why no one has thought of that yet, especially since sweatshirts are so in style right now.
