Warm and Thick
I like these socks, but they are so thick that I use more like slippers around the house versus trying to shove by boot over them.

As Advertised, will buy again
Got mine primarily for sleeping, feet get cold at night. Very satisfied and extremely comfortable. Will buy more for wearing with my boots.

Blue Flames
These are the greatest socks! My Dad is 93 and this is now the only socks he wears! He wears them all year long, says they are warm or cool, depending on the weather. He has 10 pair, and I'm ordering that many more! He loves them. That's a good review right there!

Thermal Socks
Without exaggeration, your socks are by far the most phenomenal feeling Socks in this beautiful planet!
I not only purchase them for myself ~ but my family back in Minnesota and Wisconsin!
In addition, they easily slip on and off - for those whom have a challenge at this process - it's a real breeze!
Many many thanks!!!!! -

blue flame thermal socks
I'm enjoying the blue flame thermal socks I purchased. Not as warm as wool for these cold Minnesota winters, but still a very good sock for the money. If you don't want wool socks then these would be very good socks to purchase.

Blue Thermal Socks
Ordered my husband a couple of pairs for Christmas and he loved them so much, I ordered more for him and also ordered myself a pair and love them as well.

Heavy socks
I sent them to my daughter where it is very cold & she said she loved them but they didn't fit in her shoes because she has orthotics but the good news she wears them around house & keeps her feet toasty.

Blue Thermal Socks
These are really nice socks at a great price. Soft, cozy, and very warm. Wore them today with temps in the 20s and windchill temp in the teens. Kept my feet nice and toasty. My feet fell "toes over heels" in love! Buying more.
