Does anybody have pics or a quick and easy description of the best way to do the feet mod? I've been trying to pull the heel off of the figure's boots but it seems like I might tear the rubber. I remember somebody has posted how to do it a few months back.
You are going to have to do some cutting. Using an exacto knife, you want to slowly cut at the seam along the bottom edge, between the hard plastic sole and the rubber.
Go slowly, a little bit at a time, while heating the rubber up in between slices (with a hair dryer). Tug the rubber slightly from the top, as if pulling it off of the hard plastic, and use the knife to slice right at the edge, where it joins the hard plastic and is stretching. Keeping the rubber heated up makes it easier to stretch and cut with fewer imperfections in the process.
If you are slow enough and good enough, you'll actually only be cutting through glue. If not, you'll also be slicing through a minute amount of rubber as well (it's hard to get it exactly on). Don't worry, after you finish the job, this won't be visible - it'll still look like new.
Start at the back of the heel and work your way around in both directions. You don't actually need to get the whole rubber portion off - I only cut halfway around the foot in each direction. With the rubber halfway removed, I could pull it up and over the shattered hard-plastic ball socket inside, like a sleeve, exposing it so that I could dremel the shattered socket plastic away.
Then I placed a new ball socket (taken from another Hot Toys foot) and used hot glue to stick it into place, where the old shattered socket used to be. Once it was settled, I further sealed it in with some superglue.
Then I simply allowed the rubber sleeve to fall back into place, after first lining a little bit of superglue along the inside edge of where the rubber and hard plastic sole meet. I used my fingers to hold the plastic in place for a few minutes, while the glue dries. The pressure from my fingers also ensures that the rubber is glued down enough so that it's impossible to see that it was actually once cut, hiding any imperfections in the slicing process.
Let the glue dry for 24 hours and you should be good to go. It looks just like new, except with a non-defective ball socket, and there's no deformation or evidence of modification.
