size wise I fall right in the middle of the L/XL size. I bought the jazz tan, black, and lightest pink. I found the tights to be on the small size, but with careful repeated effort got them on. As for 30 years experience with support hose, they are thin and do not appear to be to made with 25% spandex. honestly, disappointed and feeling a bit ripped off.
These tights are true to size. Top quality material and the wide waistband is line-friendly. Won’t be buying anything but this style in the future!
I like the soft waistband that doesn't dig in or roll. They're easy to pull on, although I could use a tiny bit more compression. They're matte, not shiny, which I like. And I turn the toes around so they cover my heels, over my shoes, giving me a longer leg line.
These tights are absolutely seamless, even on the convertible feet. Waistband is really wide so doesn't unflatteringly dig into your waist. Run small. Most durable of the seamless tights I have tried.
