As Twitchy reported on Sunday, U.S. Olympic Track and Field athletes are unhappy with Olympics Rule 40, which bans athletes from mentioning their sponsors.

This is what Ritzenhein, a distance runner, retweeted:

Ritz has had a long and storied running career, highlighted by an American Record in the 5,000 meters in 2009. He will be representing the U.S. in the 10,000 meters, which will take place Saturday evening. Twitchy wishes him — and all U.S. track and field athletes — the best of luck.

Oh, and by the way, that does look like a cool shoe.
