Hi Laura,
I'm not sure these would fit the bill, then, so to speak. I can't really say, though, because I haven't tried them. Seems to me this is mostly a marketing gimmick (but an interesting one nonetheless).
When you say you're looking for comfortable pantyhose, do you mean ones with support? ones that don't sag or bag? ones with waisbands that don't keep rolling down? ones that hug without too much tug?
I think the first thing about being comfortable in pantyhose is to make sure you keep your legs clean-shaven, Laura. Most pantyhose will sag over hairy legs, but stay put against smooth skin. Well, relatively put, anyway.
My favourite brand: DIM (or Diam's). They're almost like a second skin and so sheer (yet strong) that running my hands against my legs almost feels as though I'm wearing nothing. Plus, they catch the light just so. Of course, they're a little bit more pricy than usual hose.
Good luck in your pantyhose hunt, girl!
Love,
Christina
