I was planning on making her barefoot, but unfortunately there is not a full foot model under the sandals. Normally that isn't a big deal since I can just add the foot model in blender (can steal the foot from her C3) but her skirt thing uses APEX physics which isn't extractable, therefore if I edit the model in blender to add the foot, the skirt physics will be gone. So the options were to1. redo the APEX physics (which I know nothing about and isn't possible in blender),2. do physics the classic way which requires me to make all the bones for the skirt, then re-rig the skirt to those bones, then add the physics to the skirt, then add proper collisions to the skirt, then do the same for any other animated part like her hair since all physics of a costume is one file, therefore if I want to change or add anything, I have to redo it all (which is more work then I was planning to do for this mod)3. delete the skirt thing from the costume (which I liked and didn't want to remove)
