Nice suggestions above; if the fins rubs and is injuring your foot, the fin is not the right size. If it was me, I would change the boot thickness and see how that works.
Keep in mind that feet do not always have the same geometry; ie: the right foot may be a diff girth compared the left. There are physiologic reasons for this as well as anatomic reasons. I am not saying that your right foot could be size 10 and your left 12. There are subtle differences though. When was the last time you looked at your foot?
