Nontheless, I did discover that some 'myths' about wearing wading
belts seem
patently untrue. In my test, there was absolutely NO BUOYANT EFFECT
from air
trapped in the legs, as it was squeezed out when I entered the water.
I
would maintain that any fisherman who was standing in water deeper
than
their waist would have the same thing happen as they entered the
water.
Therefore, there is no trapped air to float up your legs.

THIS IS ONLY TRUE IF YOU HAVE NO AIR IN THE LEGS TO START WITH. From
personal experience I can assure you that with air in the legs and
belt firmly buckled your legs will float to such an extent that you
have one hell a job to keep your head above water.

I can also endorse never wade alone.
