Girls, is it true that pantyhose or nylons makes your feet hotter/sweatier than socks. My girl hates nylons and complains about sweaty feet.?

Nylon doesn't absorb perspiration, so, yes, they will make your feet sweaty and uncomfortable.

Yes they can cause sweaty feet

Yes the nylon makes it difficult for you pores to breathe.

Cheap ones with high denier will, but not good ones, like Wolford 9 denier. You just need to bu her good ones.

Because nylons are so much thinner/sheerer than socks, they wouldn't make her feet sweat more than socks would. Many socks these days have man-made fibers in them and since socks are thicker and a tighter weave, they would retain more heat than nylons which would result in more sweating.

She might be telling you this because she doesn't like to wear them. I have a thing for seeing nice legs in nylons but my wife doesn't wear them as much as I wish she would. Just a thought.
