Excellent sock for the value!  I did receive the wrong pack of socks, but Amazon absolutely made it right and assisted me very quickly.  These socks are thin but not the thinnest I have ever used (I could only see my skin through the sock when I flexed (see pic)).  They are soft, not at all stiff or scratchy.  These are the perfect warmer-season sock in my opinion (not so thick your feet are going to sweat profusely in your sneaker on a hot day).  The fit is great, stays on the ankle (not stretched or no lack of elasticity here).

My true shoe size is 8 1/2, these fit perfectly.

I recommend these as a value sock pack, and I would buy these again.
