Hey Amy! Thanks for your reply!
See, my thong slippers LOOK nice...and I had wore them once before I had that "cut" experience, and it was fine! (But, see, I didn't run in them before!

)
Also--what you said about the weight being a lot more on the bottom and the thong part being too thin...ahh, that might be it

. Well, on the other hand, maybe not? Well, it LOOKS the size of a regular thong, but it's heavier when you pick it up (b/c it's wooden).
And, also, the thong part is made up of softer material than regular thongs (can't think of the name of the material..but feels really nice to the touch)...and I thought it would PREVENT problems!
Oh, Amy, are there any invisible band-aids nowadays? I have really light-colored feet, and then that day I had dark-colored band-aids on (friend gave them to me), and it looked ridiculous on me!
Ahh...we endure such torture to look good sometimes...LOL...
