Okay, so I didn't want to go to the cobbler and pay him to install some snaps in my boots for the shoe armor. I also didn't want to shell out a bunch of money for a professional snap setter. Here's the cheap as dirt method I came up with for installing the boot snaps.
Step 1: Drill a hole in the heel of your boots where the snap will be installed.
Step 2: Place the snap in the hole just like you would with any other snap.
Step 3: Purchase a 2" C-Clamp from Home Depot for $3.97
Step 4: Glue/Epoxy the pivoting end of the C-Clamp so that it won't move around when you clamp down.
Step 5: Take a Regular Snap Setter and cut off the end with a metal cutting wheel on your dremel
Step 6: Place the snap setter end into the snap just like you would any other time except now the setter is way too short to hit with a hammer.
Step 7: Place the clamp over the snap and start screwing down onto the setter. It may take a couple of tries but you will get it.
Step 8 (OPTIONAL): Epoxy the setter tip onto the clamp itself. It should increase stability, but your clamp will be permanently ruined (not too big of a loss considering it cost $4).
