These are what my feet needed. I keep my home about 64 deg all winter (even when 0 deg out) and am very cold sensitive. For 2 winters they have proved cozy and durable. I do wear them to drive my girls to school on my days off and they are holding up well. I do miss the plushness they had the first year but they still feel good to put my feet in after a 14hr shift. Snug fit, when new, is good as the bulk will where down after worn a couple weeks. My teen girls are always trying to steal them from me. So keep them close;)
