Here's my thoughts on waders for use in saltwater: bootfoot insulated
waders are the best - Redball is the maker of my current pair but others
are just as good. You shouldnt need to pay more than $55.oo
Buy bootfoot waders because they are about 2x to 3x faster getting in
and out of than stocking foot models. (you can use the advantage to
beat your companions to the best spots)
Buy cheap waders because they all leak eventually and its fairly
easy to reinforce/protect these things. Buy a tube or two of Goop
(it doesnt matter which type) and smear all seams and stress areas with
a thin coat. Neatness does not count.
Buy insulated waders because they will allow you to go with no socks and a bathing suit during the warmer months and you can easily add clothing as
the temps drop. A lap or two of duct tape can make a quick tailoring
job on the waist or legs if needed.
If you walk on slippery slopes, (and who doesnt ?) buy a handfull of
3/8" hex headed sheet metal screws. Ten minutes with a screwdriver will
have you sporting a new studded look. Some of the screws will pull out
but so what ? They dont seem to hurt the boots and they are some assistance
in the field. One piece of advice: make certain you remember to take the
waders off before walking in the house. Its never a good idea, but in this
instance it will end badly. (they also cut up lines too)
As for getting trapped in the water while wearing waders: this summer I went swimming while wearing waders without a belt. I have to say it wasnt too
bad. The trapped air lasted for quite a while and even when it was
completely gone I could maintain balance in the water. The real problem
was in climbing out of the pool. That was not easy. Now no one wants to be
knocked down in the surf or slip into a estuary but with a belt and some
level of common sense a sure death is not automatic.
But just to be on the sure side of trouble, I suggest you buy a belt and one
of the many inflatable belts/pouches which have become available.
