Help on converting shoe sizes

[wnxmegax]

Hello everyone I have a big problem that has been lingering over my head for 2 days now. What I am talking about is High Heel shoes. I have been browsing the web and found some amazing High Heel shoes they look amazing on my character. Although their is one problem with the legs and the high heels they don't connect right. I know this is a problem because each of the high heel shoes are supported for HGEC bodies, but I want these shoes to fit my DMRA body. I will upload a pick shortly to show what I mean by this. I have learn how to connect and fix the meshes in blender but when I export it the bones being use becomes broken and doesn't show up in game at all idk what to do. Below are the screen shots I mention.

The first one is to show what I mean by a problem you can see they don't connect to the legs. The second pic is after I connected the meshes to the legs although something goes wrong with the bones when I export idk what happens exactly.

Nvm after few days of messing around with the model I discovered using the original bones is much better than trying to use a new set of bones and I successfully converted the HGEC heels to fit DMRA legs. This also works for changing bottom outfits to DMRA as well.
