I never got to wear them.  I tried them on to see if they fit and took them back off again.  Two days later I went to put them on to wear with the dress I was going to wear to go out, and found that there was a big hole in the back part of one foot.  It must have happened in taking them off when I tried them on, but I wasn't aware of anything having happened.  I had to put makeup on my legs and go bare legged.  Not a happy camper.  If we can make materials that astronauts can wear in outerspace, we should be able to make nylons that can survive a little longer than these did.
