Freak of Nature

My left foot is a full half size larger than my right. This is not usually a problem, except for after our long runs, I've been having a lot of toe pain (stop laughing at me. My toe nails are turning black and the kids in the nursery keep stepping on them) So Chris suggested I get a half size larger than usual when I bought my new pair of shoes. The left shoe fits perfectly, but I've got total clown foot on the right.

In stores I always want to sneak two different size shoes in the box, but salespeople ALWAYS check. Isn't there anyone out there who wants to switch a right foot size 8 1/2 Saucony for a size 8?
