Mine have.This thread has made me think about why I still have one pair of "hard-soled booties" that I use only for Bonaire (or potentially some other rocky shore-diving location), while for the rest of my boat diving I use common floppy-soled booties in which I put stiff (and expensive) insoles to make it easier on my foot muscles, help reduce foot cramps, etc. My Bonaire booties really ought to become my normal booties.
