That last thing RKTNMYPKT said is probably the bottom line when it comes to footwear, good motorcycle boots will minimize the trouble you are in if you step in some oil.
I found out why two weeks ago (the last time I rode my Harley) why I'm not too much of a fan of the 3/4 helmets. It was raining hard and the rain went down the front of the visor and then went up the backside of the visor...visibility near zero. I'll go back to a modular helmet as soon as I pick up my new ride.
