New shoes

I bought some new trainers about a month ago, but because I'm fastidious about footwear, I hadn't worn them at all. I don't like to wear new shoes, because I'm worried that I'll get them dirty. As a result, it's often months that they'll sit unused, until my embarrassment at my irrationality overcomes my foibles, and I put them on. So in this case, a month isn't actually that bad; there's a pair of smart shoes I bought in Oxford in February which I haven't worn yet.
