I have been buying Tight-End Tights for years.  They are by far the most durable tights on the market.  I have purchased three or four pairs over the years, and although they do start to show some wear, like getting pilly around the feet, they are all still in rotation.  It must be impossible to get a run or hole in these things!

This is the first time I have purchased the high-waisted version.  They are more flattering, but less comfortable as they come up past the bottom of your rib cage.

On a weird note, this pair had a weird smell to it.  I washed them and they retained the same smell.  It must be the material that it is made of.
