These are pretty thick and plushy.  These area my "at home" comfort wear socks.  I am not giving these a bad review, just a kind of sock that may be too thick to wear inside boots even some sneakers at first.  Mine are still plush and thick after 6 washes, but that is just indicating that these are good quality and they have also retained their shape, as if made with some sort premium elastic material.  Good socks for that end of the year extreme cold weather.
