I have worn this brand and style for years. I love them. Some reviewers have complained that they run, which is true. It's the nature of nylons. But given has sheer these nylons are, I think they're extremely durable. If you are careful putting them on, you should be fine. They fit like skin, so (knock wood) I don't recall ever getting a run while they were on  me. It's more likley from my nails when putting them on. So just make sure your nails are smooth. :) I always machine wash (in a laundry bag) adn hang dry.

I've tried much more expensive nylons (e.g. Woldford) but none look natural. With these nylons, people literally don't know I'm wearing any, which I just love. They even feel pretty natural (not exactly as smooth as skin, but close). I hope they never stop making these nylons. And I almost always buy mine at the drugstore. But they're a little (barely) less expsive on Amazon (moreso for me because credit card cash back). That said I definitley think they're authentic Legg's brand (not immitation imo, as some reviewers have suggested)
