My shoe shrunk!

I'm an avid crocs wearer, so I own quite a few pair.  They are easier on my feet than your average shoe, and when you are pretty much standing all day as a teacher, you want comfy shoes.  Since I can't wear sneakers with every outfit, I vary and wear different kinds of crocs.  I have two pairs similar to this design below (minus the little jewel thing) in brown and in black.



Well about a month ago, one of my black shoes fell out of my workout bag in the car and I never brought it back inside. I didn't even think about that being a problem until today when I planned on wearing them.  When I went to put on the shoe from the car it was like shoving my foot into a shoe 2 sizes too small.  It was tight, and my fat foot wouldn't fit.  I felt like one of Cinderella's ugly step sisters, when they tried to shove their big foot into Cinderella's petite little shoe.  My shoe had shrunk.  I knew the car was hot, but I didn't know it could shrink my crocs.  Now if I knew the secret formula of time in the sun, and length of time in the car, I would leave the other in the car too, so at least they could be a matching set that I could give away to someone.  Until then, if anyone knows of someone who wears a 10 on their right foot and probably an 8 on their left, let me know, and I'll send the shoes their way.
