1. A cutting tool. A razor works best, but anything good and sharp will do.
2. A pin punch or a thin screwdriver.
3. A pen or pencil.
4. Replacement cleat receptacles. These are availible free of charge upon request. Simply e-mail email@example.com with the subject "Cleat Receptacles." Indicate how many you need (limit 6) and supply your shipping address and we'll have some sent out.
Once you have all your materials flip the shoe over and use the pin punch (or screwdriver) to lightly tap on the receptacels. What you are trying to do is make a mark on the inside of the innersole which you'll make use of later.
Look inside the shoe and find the marks where the cleat receptacles have pushed up on the innersole. Using a pen or pencil draw a path around those holes to mark where you will cut your window.
Cut along the line, be careful not to make a complete circle! Leave one side uncut as a hinge. Pull up the innersole revealing the cleat receptacles.
Replace the problematic cleat receptacle(s).
Close the innersole window and replace the comfort insole.
You are done!
