Warm, comfortable, neat-looking, pillow-esque
These socks are so wonderful. They're like mittens for your feet. Even on the coldest day, your feet will be toasty. Once you wear these, you'll never regret the money you spent on them. I even wear them in the summer. They feel like walking on supportive cushions. They are also sewn/designed in such a way as to not crinkle in your boots.
One problem, though, is if you have wide feet, they can be uncomfortable when you put them on. I wear a size 12 with 6E width. For me, they can be a little tight, but, admittedly, I have an odd shape to my feet with a lot of width towards the middle and heel of my foot. These socks do stretch out, too, once you put them on in the morning.
Also, if you've got gross and callused feet from wearing bad boots, I recommend these socks with Redwing boots to keep your feet looking decent.
