Importing over existing shoes

If i want to just import a new shoe over an existing one (i.e sh075)
and using a bmp and fshx, I change that shoe..
Do i need to do it in any other viv file than
sgsm/common/xshoe.viv ??

Here is a reply from Seraph
You can modify the fsh files in both the sgs/common/xshoe.viv
as well as the one in
sgsm/common/props/shoes.viv

and import new pics over those and it should work fine.
