Bringing this one back from the dead...
Apparently this is a super common problem with these boots where the screw on the outside ankle support will work it's way loose leaving you very vulnerable to foot injury. I did not have much luck with vendors or a* offering to repair them and read other accounts of people who paid for a repair only to have it come loose again months later.
I finally decided to repair it myself. I located the screw where it would naturally screw into the support. I then cut through the insulation from the inside with a box cutter and all the way through to the leather exterior. Yes there will be a hole but it is covered by the screw. It helped to poke at this part a bit from the inside and touch with with the cutter from the outside. Once there I thought it would be a 2mm Allen like the toe slider but it is
#2 Phillips driver bit (I had to cut the first one a little more than I wanted since the 2mm worked briefly).
Make sure you can easily locate and screw in the attachment point so you don't have to fight with it after the next step. I then applied red loctite (I'd like it to never come apart) and fastened the screw with the Phillips head. Once hand tight I did turn it just a hair more by putting a 1/4 socket wrench on the bit to make sure it was driven home. If you only make a small vertical cut it shouldn't bother you but you can sew the insulation if you want.
It did appear like there was some loctite or something on the screw before but only on the threads that would've just barely gone into the part they thread into. Hopefully the newer V2 of this boot doesn't have the same problem.
I hope this helps anybody else running into this issue!
