I think Inside Box could help, if your opponent has one outstanding inside player. However, you should also make sure that your best defender is suitable to defend in the post. If he's more outside oriented, you might fall into the trap of your own making.
For me there's no problem with Inside Box, because my best defender (OD+ID+SB) is inside oriented. I use Inside Box, when I feel that my opponent might try to outsmart me and play his best inside player out of position.
However, I haven't tested Inside Box specifically against Inside Isolation offense. Maybe someone else will enlighten us.
