Remember the Mickey Mouse boot stories that you pumped air into the valves and that's what caused them to work so good.
After hearing this guy say he had never been duck hunting that his feet didn't freeze off I loaned him mine.
He was duck hunting on the Mississippi river out of a boat blind...he owned a 4 Wheel Drive accessories store after he got back he bought about a half semi tractor trailer load of the boots in various sizes.
In the late 1970s I had a pair of the Hoods marked USMC with no high altitude air valves I recall they had a slick rubber inside.
Myself I think the Bata Rubber Co. ones are the best.
One pair I purchased came with the military instructions pretty interesting read.
I live down South and I have two pair.
If I lived where Ted was I'd have 3 pair for myself two for the wife and one for the dog.
