Im in a love/hate relationship with these socks. I love how plush and soft they are. I love how great they fit and even though they aren't tight on my calf, they stay up. I hate that they make my feet sweat. The very first pair I put on ripped a hole when I pulled em up tight. My finger went right thru them. Ive been wearing them with work boots and have yet to wear them with anything else. Maybe my feet would sweat so bad in tennis shoes. These are thick socks. These aint wal mart specials.
