Ok, this is a well known but complicated process:
1) The first step is to check the size of shoe, this is very important. They must be between size 9-12 for this to be of use.
2) Next you need to go to Fillmore and 9th Street and ask the Hot Dog salesman to direct you to a man named "Big Earl".
3) The passcode to enter Big Earl's lair is "Gerald Ford", they will ask you a question.
4) This is of the utmost importance, DO NOT LOOK BIG EARL IN THE EYES UNTIL HE HAS ACKNOWLEDGED YOUR PRESENCE.
5) Offer him the going rate of $5,000 and ask him to please wear your shoes for no less than 1 month, to break them in properly.
6) Enjoy your new shoes, properly broken in by a 500 lb. gangsta!
