Excellent, thanks for the answer, how do I do this? And possible follow up question, can I do this through BS/OS, Skyrim CK, or Nifskope?

I tested it out and the only different step I did was not use the default CBBE feet reference. I grabbed the feet NIF from a random mod that already had high heel feet meshes. Here are the steps I did -Select meshe(s) -> Edit -> Remove Skinning -Double click mesh(s) -> Geometry Tab - > Check off "Skinned" -Click mesh(s) -> Partitions Tab -> Change type to "37 SBP_37_Feet" ->Click Apply -File -> Load Reference -> Browse ->Select file that has Feet reference -> select "Feet" shape in the dropdown ->Leave merge buttons unchecked -Select meshe(s) -> Conform Selected -> Leave everything default and hit ok -Select meshe(s) -> Right click and select "Copy Bone Weights" -> Keep default for now -> Right click and select "Mask Weighted Vertices" and check around to see if everything is masked -> Copy Bone Weights again and adjust "Search Radius" as needed until the whole lower foot is covered -> Delete Feet mesh when done -File -> Load Reference -> Select CBBE 3BA Body -> Check off "Sliders" under Merge section -Conform and Copy Bone Weights like earlier and delete body reference So far, it seems to work but please let me know if there any better ways or missteps that I did

It worked! Thanks for the help! For future projects, should I keep that in mind from now on or was this a random instance where it mattered?
