I fish year round and my feet don’t get cold. It’s one thing to be fishing and moving constantly, it’s another to be standing in one spot with very little movement when the water is below 40 degrees. There’s absolutely no chance I would hunt in stocking foot waders. When I’m fishing steelhead I cast, swing my fly, take two or three steps and repeat the process. I’m never static and I frequently hike between runs. I’ve done my fair share of winter steelhead fishing in Northern BC, so I’m well versed in cold water. Standing knee deep in 40 degree water (or colder, I’ve broke ice more times than I can count) while hunting ducks is another thing entirely. If I’m hunting in a raised blind then I’m wearing bibs and muck boots. Most pit blinds have water in them and it gets just as cold as the air or even colder sometimes. Even sheet water is no fun to be in without insulated waders. Maybe I just have cold feet but I’ve been doing it for more than 30 years and I’ve learned my lessons the hard way many times.
