Feets too big

I think my feet are getting bigger. I have two older pare of shoes that fit just fine a couple years ago. They are too small now. They are both 10 ½. Normally I ware 10 ½ in shoes and 11 in boots. My toes hit the front now. What the hell?

People tell me I'm nuts. Your feet don't keep growing, right? Maybe the shoes shrunk over the years.
