Comfortable and very cozy. My job keeps my feet wet and cold in the winter. These really help.

I love these socks they are so comfortable to wear around the house and with snow boots! They feel kinda weird with sneakers and such since there so thick but other than that their awesome! Will definitely be buying some more!
