That's not a haiku.
"Piles" has two syllables.
You old foot pervert.

Yes, they leave shoes out.
Strange that foot-lovers aren't called...
pedophiles. Doh!

Much like Santa Claus,
You can leave "gifts" in their shoes.
Instead of their socks.

Gooey, sticky gifts.
It will increase shoe lifetime.
Chinese products suck.
