If instituting special sanitary rules is what it takes to keep feet, fine, but there’s already an unwritten rule: are your hands gross? Wash them before competing. Feet? Same. Feet are not inherently gross any more than hands are. Both can get nasty, and both need to be washed from time to time.Well, I would compete if it came to my locale, but it would be a good thing to institute some rules for sanitary reasons. That's what I say, anyway.
