I keep a pair of flats in my car because driving a stick shift with heels is ... well it's easier in flats. I just cleaned out my car and I can't find the right shoe. It's like totally vanished. The only thing I can think of is it must have fallen out some where recently. I'm bummed as I liked that pair. Oh well, at least I still have the left one which I need for the clutch.
So now, I guess, I've only got one flat and NO the spare in the trunk ("boot" for you EMEA folk) won't work!
Sorry - I had to add that.
