Being a person that Likes to play with mods, especially clothing mods (as it increase the variety in the game).
I have found that if you plan on using multiple clothing mods together.
You need to use the stream2update tool from Minimaul's SR4 toolkit.
Note: There are a couple clothing mods in the SR4 adult section as well as Superdemus's and Mikado's in the regular SR4 mod release section.
If you mix and match any of those mods, then you need to run the stream2update from the SR4 toolkit.
It will update the customize_items.asm will all of the clothing *.str2's that you have in the root folder of SR4.
If you do not then game crash's, items not appearing correctly in stores, and other crazy things can happen.
Oh and Superdemus, I was not able to get the hot boots to work.
Currently we can not add items to the asm file (we can update with existing content but we can not add new content).
Luckily, the wildchild pants are in the SR4 asm file so moving the cmorph from SR3 over worked.
If I knew how to hex edit the asm to add the 4 sections of code from the SR3 ASM for the shoes, then I'ld have a WIP up... but until the asm to xml tool is release I'm on hold.
