I work outside (Maine weather),  footwear and socks being critical to remaining comfortable. This sock is perfect for Fall and Spring use, but likely too hot in Summer and too cold in winter. Also, I wear a slip on style boot, and the extra thickness works really well as there's a little room in the boot. These are superior socks to typical Hanes or Fruit of the Loom junk. I've owned numerous Carhartt socks and these are great quality so far. Any extra cost in comparison to other cotton socks is easily justified by the increase in thickness and quality. They really are comfortable.
