The evidence

 

Two pairs of shoes which mysteriously don't fit, except in the shoe store.

What the hell is it with shoes?

Or with my feet?

I go to a shoe store and buy a perfectly nice pair of shoes. I try them on. Walk around in them. They fit fine. Take them home.

A couple of days later, I decide to wear them. The shoes magically no longer fit. I cannot insert my feet in them without howls of pain.

What gives?
