These socks are great -- soft, cushiony, and moderately thick -- thick enough for lots of comfort and quality, but still thin enough to fit into my shoes.

Will update in a year about how well they've held up.

ETA: Not quite a year later, but ~10 months.  These socks have held up really well and I've been very happy with them.

An added bonus to them is that they have a little "C" logo on the top of the bridge of the foot.  In this pack, there are 3 colors of logos -- purple, blue, and pink -- 2 pairs of each color.  The reason I say this is an added bonus is because having them color-coded like this has been a nifty way for me to keep track of missing socks.  For instance, putting laundry away and seeing that I have a lone blue-logo sock missing its partner.  So I set it aside in the dresser thinking it's a lost cause.  2 weeks later, find a single blue-logo hiding under the couch -- aha!  So the socks are reunited.  It might just be me, but I think it's handy lol.

If you don't want the trouble of having the colored logos match up, then that's fine too -- the logo is positioned in a spot that will never be seen one you put shoes on, so no one will ever know.
