Saga of the sunglasses

I got these sunglasses from a race as a give-away many (10+?) years ago -- long enough ago that I don't even remember what race.  I started racing in them because they were cheapo shades that I could throw off at any point if they annoyed me, without blinking an eye about it.  However, they then become invaluable to me!

They may be cheapo shades, but they are the most comfortable sunglasses I've ever found.  They stay in place and don't bounce or slide.  The ear pieces don't rub.  They aren't too dark or too light.  They're perfect!  I don't care that they look like cheapo shades.  I've worn them through many marathons!

When I was running Yassos before the Mesa-Phoenix marathon, I set these sunglasses by my nuun bottle by the side of the track.  I started the workout just as the sun was coming up and didn't need sunglasses initially, but I knew I would likely need them at some point.  I scooped them up on a recovery jog without stopping, and noticed they were pretty dirty upon putting them on.  So while still running, I wiped them off on my shirt and in the process the frame broke in one spot and the lens popped out and fell onto the track.  I was devastated, and dropped them back by the side of the track, sans one lens, before starting my next repeat.  Then on the next recovery I scooped up the lens that popped out from the track.  In a stroke of genius, I slipped it inside of my gloves that I was shedding and dropped the package by the side of the track, determined that I was going to repair the sunglasses.

And I did!  It just took a little superglue and a little effort.  They lasted through Rock the Parkway, where they got a bit fracture again, and are now barely hanging on.  I'm considering giving up attempting to fix them again, and I bought another pair of running sunglasses that seem to be working okay.  My poor, poor cheapo shades.

Do you have any running gear you don't want to let go of like this?
