I recently bought a new pair of shoes. I usually wear a size 8.5. The pair I ended up purchasing are a size 8. And they are still too big.
Today I'm wearing a pair of shoes that I purchased in February or March of this year, which I've only worn a few times. Once again, too big. I don't remember them feeling this loose.
I'm suspecting that my loose shoes have something to do with my recent weight loss. When you lose 50 lbs, the fat has to come from somewhere, right?

I'm just glad I'm not crazy.
