I have been wearing these every day with hiking boots, trampling through thick underbrush, fallen trees, muddy soil, and beaches. It's HOT y'all. The sweaty boot feet are real. These socks are great! They're comfy, good snugness without being uncomfortable, and they soak up a lot of sweat. By the end of an 8-10 hour field day, they are damp- but I don't notice until I take my boots off, and the socks are coming off then anyway. They keep my feet comfortable through the day, and wash really well. Great buy, especially for the price.
