Well, I am sure to be in the minority here when I say it, but here goes...
I hate high-heels. There, I said it. I hate em, hate em, hate em. They make me taller, are near impossible to be comfortable in (even when they 'fit perfectly') and can get caught in pavement gaps, sidewalk grates... all sorts of inconvenient places. It's the modern, western counterpart to the old, eastern foot-binding tradition. I honestly believe a man whose goal was to limit female mobility invented the things. We don't want our ladies wandering off, now do we? Well, they'll never get too far too fast in these suckers. Muhuhahaha!
Or maybe a podiatrist with a failing practice trying to drum up new customers.
Anyhow, flats ftw!
