Polar ExtremeMen's Polar Extreme Moisture Wicking Insulated Thermal Socks in 4 Great Colors (Black),6-12

Warm and cozy. You need a little space in the shoes to fit properly. I am glad I purchased them.

Very warm. Used for my only pair to wear while fishing a cold river with waders on. A tiny bit small for size 12 shoe

I bought these after finding out my feet were uncomfortable because they got sweaty and cold because of the sweat, and other socks didn't really help. After trying them for a couple of days, I can confirm they're really comfortable, but kind of ineffective at the whole wicking away moisture selling point. My feet are still sweaty and cold. So if that's your decision making process, I'd do a little more research and find a different product. And if you do, can you let me know what it is? 3 stars because I don't hate them, they're comfortable and will probably be just fine for going out in the cold winters here in MN.

The sox keep the feet very warm. The only thing I miss are little rubber grippers on the soles for walking around the house in sox. Overall, a great product

Great winter socks. Not bulky. Buy one pair and try them with your shoes and boots.

Not that warm. I have another pair of fuzzies over them and still cool. I'm sorry but won't buy again.

Keeping my feet warm in the winter

Perhaps not the warmest sock I've ever bought, but definitely the most comfortable! I live in a cold weather climate, so I bought this sock to be a second layer over my normal socks. It works perfectly for that. I'm not sure I'd wear it alone as my only sock in very cold, snowy or wet weather, but as a layering sock, it's perfect and exactly what I was looking for. I immediately bought two more pairs.
