Can't say I have. However, there has been a couple times where I stumbled on an imaginary (fill in the blank) whilst walking and luckily no one seen me in action. Lol
Yes, last year I was walking barefoot through my bedroom and my toe caught on the carpet and folded under as I stepped. At first I thought I just sprained it, but it turned out to be a slight fracture. I agree...not fun.
