This socks are typical Carhartt products in that the construction quality is excellent like every other Carhartt product I have every purchased.  I have two issues that might not affect others.  One is that they are not "soft" but slightly scratchy.  My guess is they will last a very long time but I am accustomed to Wigwam's much softer products.  Two is that for the warmth, I subjectively feel they are thicker than some others.  The boots I wear with them allow the thickness but the combination of slightly scratchy and slightly snug means the only time I wear them is when all my others are in the laundry.  Let me be clear they are quite warm and I expect most would be very happy with them...me just moderately so.

Follow up...after six to ten times through a wash/dry cycle, I really like these socks quite a lot more and would rate them 4+ stars.  Much softer.  Contrary to at least one other review, these socks are wearing exceptionally well.  I spend quite a bit of time walking around with no shoes in the winter time (to keep floors clean and spouse happy)and they still show no signs of wear at all.
