To get rid of the boot order, my son tells me there is a shampoo for
neoprene boots. However, someone else mentioned that Pinesol, and I
suppose Lysol, might work well too. I suspect that a full dose isn't
needed. Anyone know the recommended approach to using one of these 'sols'?

Sink the Stink and Mirazyme are a waste of money, as they don't work any
better than proper care does. There are two things that are important
for keeping neoprene from getting smelly.

#1 Rinse and DRY it thoroughly after use. Odor causing bacteria cannot
grow without moisture. This is the single most important preventative
measure you can take. Drying in the sun is the best method, rapid air
drying is second best (ski boot dryers are handy for this). Stuffing
boots with newspaper or cedar shavings helps if you can't get them dry
any other way.

#2 Eliminate direct skin-to-neoprene contact. Bacteria feed on skin oil
and dead skin cells. Even wearing thin socks inside neoprene boots makes
a big difference.

Lysol, Pinesol or just plain diluted bleach will all help to kill
bacteria and the odor they cause, but nothing will keep boots smelling
good if you don't dry them adequately.
