When you say symmerised do you mean you used the mirror modifier?
Here is what i did with the shoes i made.
Note im at work so trying to remember the exact names of things is tough for a 61 year old. Lol
Export character with high heel shoes from CC as fbx
Import to blender and delete the shoes.
Create a plane and cut it in half and positon it at 0,0,0 xyz position
Add a mirror modifier and then position the half plane under a foot
The mirrored plane lines up under the other foot.
Now build my shoe shape
Now the bit that might help your question
When the shoe is shaped apply the mirror modifier so it is not there any more
Now you can edit both shoes separate to each other.
When complete
Go to object mode and to the shift click armature,ctrl-P, with empty bones. Sorry cant remember what thats called
Now select the characters skin, shift click the shoes switch to weight paint mode select transfer weights and set the source to "by name"
Now do the uv mapping and then export and import to CC
The point that both shoes move with the same foot makes me think that you did the weight mapping with the mirror modifier still open?
Or something like that
Hope that helps
