As others have noted, there is something weird going on with some of these socks coming out of the dryer with lots of lint on them.  I washed all these socks together in a single load without anything else, and most of the darker colors came out with a lot of lint on them.  Strangely, some did not, so that tells me some of the socks are using different batches of fabric.  The lint only looks bad on the darker colors, you can't notice it on the lighter ones.  But it's really bad on some of the darker ones, bad enough to look really goofy if you're wearing anything but jeans.

Also, the tops are tighter than most socks, but I have skinny calves, so it doesn't bother me (I kind of like it because they don't slide down).  But anyone with caveman calves would likely find them uncomfortable.  The lower part is not tight at all.

The fabric is a nice medium weight - heavier than dress socks, but not too thick for warmer weather - but they might be too thick for hot, summer weather.  They are a bit heavier than "khaki socks" from LE and EB.  The fabric is very soft.
