Bike polo mechanics & fixing

Yes, I've seen plenty of people play in road shoes.

I'm not sure what Joni has against them, or why people are so concerned about slippyness, if you are down, you are down, who cares if it's then slippy...

Sure, if you had the choice now, get recessed ones, but I wouldn't change them until you've tried it out, and decided you don't like it.

Who plays in road shoes? This seems ridiculous to me.
