they are presented as cotton crew sox but they are actually thin dress sox

Excellent product!

I've purchased at least 4 sets of these socks The are soft and comfortable but do not last long. The toes have holes in them after just a few months. Please improve this product and reinforce the toes

Husband loved them. Worked great under suit pants!

When it comes to plain, ribbed, black, dress socks, you can't get much better than these Calvin Kleins. No they are not all cotton but a combination of acrylic, rayon, polyester and spandex - but they look good, feel good and I get a sense that they will last a long time. For me, a good buy.

The shoes were so comfortable and I received so many complements on how good they looked.
