We in the Great Lakes area are experiencing a lot of fin (CRACKS)
particularly on the bottom of our fins.
The area is invested with Zebra Mussels, just about every rock ans shoal is covered in them. Zebrra mussels have a razor sharp shell and Ibeleive that most of the so called crackes are infact cuts in the rubber, from steping on Zebra mussels.
I've checked my fins and My Volos, Quattros and old jet fins all have the tell tail slices in the bottoms.

Fins are not well suited to walking anyway. Are you walking in them?
