I'd say Colby is spot on with her estimated miles. I did wear them most runs but I had more than one pair so it's not like I wore the same pair every day. The tights are sturdy except for that one spot where your (or ok, my) thighs rub together.

So I'd say under 1,000 miles but over 500. They maybe could have made it over 1,000 miles. I track my shoes, just not my tights
