I'm curious if anyone has experimented with different substitutes for "liner socks?"

I was looking through a close-out bin at a local store and noticed very thin, 100% Nylon dress socks for sale at a fraction of the price of liner socks.

They looked to be very well made (they were probably formal/tux socks), the right length and they didn't have any seams in the wrong places. I was thinking about giving them a try but thought I would ask about them here first. Thanks.
