You need to edit Partcutdesc
If <BasicCutType of the foot part have this <!-- <Path>.....foot path models....</ Path -->
You need to remove this <!-- -->
Any changes in this line will affect all your character's shoes, this is how <Path works
It's a way that the game recognizes which parts of the body it has to cut out, so these parts will not come out of the clothes.
ORRR
This specific shoe contains a <CutType,
Example:
<CutType Name = "UpperbodyMod">
<File> 1_Pc / 14_PLW / Armor / 9_Upperbody / PLW_00_UB_0001.pac </file>
CutType does the opposite, it tells the game which parts of the body will not be cut on a specific item, even if it comes out of the clothes, so you need to remove this line "<File ..." or Put <!-- at the beginning of the line and --> at the end..
