Most of the time I wear sensible shoes that are wide-ish at the toe and low-ish in the heel. They are comfortable and mimimise the likelihood of me falling over and breaking an ankle or two. But there's no denying that I look better in a bit of heel (because only people with Audrey Hepurn-esqe physiques look really good in ballet flats).
Wearing heels increases your sex appeal. Wearing flats increases your agility.
So I guess the question I must ask myself is this:
Do I want to be able to attract men, or do I want to be able to run away from them?
Well seeing as I already have the much-desired attentions of lovely fella, then it has to be the latter...
