replacing feet in shoe meshes

[7Synns]

I took the vanilla fur shoe mesh and used the wild huntress textures to replace the boots, going for a moccasin look. the textures on the shoe and the ankle are correct but the foot itself is still looking at the vanilla feet i guess instead of the uunp foot from the body i use.  i have tried replacing the foot on another outfit before in outfit studio but the foot is actually bigger than the shoe so it didnt work at all.  Is there a special foot mesh for things like this somewhere, like for use on high heels and or low cut shoes like this?  or is there someway to get the shoe mesh itself to look at the correct foot in the same way i pointed it to the textures i wanted in nifskope?  thx for any help in advance and have good day  pics below

Just sculpt your uunp feets to fit the boots using bodyslide outfit studio

1. Open outfit studio. click file > load outfit.. > choose load from a nif file

2. Choose your modified boots mesh with the vanilla feet already replaced with your oversized uunp feets.

3. Choose the mesh you want to modify in the right hand pane (the feets or the boots)

4. Use the grab tool, etc to mold the meshes until they match each other size
