SamNerroIn short, yes. I do find the Darn Tough's thicker cushion versions warmer than the thinner ones, naturally. These Steely socks and the Darn Tough Hunter socks are typical of my sock wear for all but peak summer - making up one part of my footwear system with good warm boots in the winter. I do have other socks that are thicker than any of my Darn Tough socks. My Wigwam Ice socks, which are the only Wigwams I have anymore, and a pair of Austrian-made boiled wool socks come out when I'm in really deep cold - in boots that are sized to handle the much thicker socks.
