These Cozy Wool Socks Will Keep Your Feet Toasty Warm All Winter Long

These unbelievably warm wool socks will help your feet stay toasty and warm when you go outside to brave the cold. Featuring a whopping 85% pure wool, the -40 degree Fahrenheit sock is engineered specifically for the most freezing, sub-zero temperatures around. The trade-off is that the high wool content makes it slightly scratchy so you may want to wear a liner underneath; however, if your bottom line is staying warm, this is the sock for you.

According to one reviewer: "I was looking for some seriously warm, heavy wool socks, and these certainly fit the bill. I spend a couple hours every day walking my dog in the Chugach Mtns. outside Anchorage, AK, and not surprisingly it can get cold. My feet are by far my weakest link, and thick wool hiking socks weren't doing the trick. Now my feet stay warm down to -5F (-20C) with 200 gram winter boots.”

The material, made from a wool-cotton-polyester-spandex blend is breathable and airy, leaving you warm and fresh.

According to one reviewer: "First let me say, I am a sock person in the winter time, hardcore. While socks do not touch my feet during the summer months, I have issues with anemia and once the snow begins to fall my poor toes get cold rather quickly. I happened to grab these on a lightning deal and they are FANTASTIC! Soft, warm and the patterns are adorable! These shall be my 'go to' winter socks for years to come.
