Walking into my spare room last night, I got the sensation of my heel going into something soft. I couldn't see anything and had a good old prod around with my heel. Nothing found I ventured on and the heel hit a soft spot again. I had a really good look this time and found my heel had gone right through the carpet. On closer inspection I think there has been a knot in the wood of the floor board, and the stiletto heel has popped this out. Luckily it isn't all that visible so I won't have to rush out and buy a new carpet just yet, but I'll be watching where I put my feet from now on.
