I really wanted to like these for winter running. First, like nearly all Oiselle tights of recent years, they are too short for me. I'm 5'8" and I don't consider myself that tall. Even though these are stretchy, the short length means I'll be battling these wanting to slide down. This was an issue for me with the seamless tights last year, which now have a hole and are not wearable for this very reason. I do think these tights will work for people who are shorter.
I also wanted something thicker for colder runs (for those below 25-degree runs). I am tempted to try the bad weather version of these tights, but fear I'll have the same length issue. Looks like I'll just keep sticking with my old pair of Tall Lesley tights. And may resist ordering any more tights from O until there are some longer inseam options.
Honestly, I would return these, but I threw away the tags and packaging yesterday when I received these a little prematurely. So I'm sure I'll find some use.
