farting shoe

So I walk into 8th grade and shake the 8th grade teacher's hand and my berks fart!

Yah they fart! My heel and the sole of my shoes makes a pocket of air and FAAAART!

I look around at my shoe and .....I didn't say what I should have said "my shoe farted!"

I just say "good afternoon 8th grade"

Yah.......so what to do? new shoes?
