Splatoon 3 Models - How Do I Fit Right Shoe?

[PAWN_EDM]

I downloaded the Splatoon 3 Inkling model and am now putting gear on it. The shoe imported from the Inkling zip only has the left foot. This would be fine if the bones of the main Inkling's armature weren't flipped for each side (for whatever reason). I really want an easy rig to pose so I'm adding "copy transform" constraints to all the bones ("Child Of" is a little janky) but, since the bones are flipped upside-down on the right half of the body, when I go to apply the constraints to a copied version of the left shoe, it completely messes up the mesh. I've been at this for hours. Help Me!™
