Don't quote me on this, but I believe they are similar to footwear used near other delicate archeological sites - no tread and very soft rubber, so you leave minimal impression on the ground.Lieju said:On a related note, I'd be curious to know what kind those special footwear that people with permission to study the lines are required to wear are.
All my searches just get me this story, and I'd love to know.
I believe they are called "site shoes" although it's not the kind of thing an average person buys, so you probably aren't going to find them in normal stores. I can't find a damn thing online to confirm this, and my books are at home I'm afraid.
Edit:
You know, it was in a damn lab book too, so I can't even google a textbook name. I'm finding references that mention foam flipflops, which kind of rings a bell. I want to say almost like a treadless croc that keeps your filthy, caustic footsweat away from the ground.
