Brother and Dad have been running Irish Setters for the past 2 years, no issues.
Brother is using the Vaprtek (I think???), no issues with waterproofing or breathability or durability. They're all synthetic, so I don't expect them to hold up like a pair of all leather boots, but so far so good.
Dad is using an old, discontinued pair similar to the Gunflint's, circa +/-2015. Local Sportsman's Warehouse was tearing apart a mannequin display last summer and had a mannequin wearing them, was going to throw them away (since they were a 6 year old discontinued boot, no tags or box or anything), and they were dad's size. He offered $10 for the boots and they took it, he's been very happy with them.
Full disclosure, my Dad and brother don't spend an exorbitant amount of time in field, but they are billy goats and put on the miles when they do go out. Between some camping, hiking, and a few hunts, I bet they've each got a few hundred miles on them and there's no sign they'll be replacing them any time soon. For the price, I wouldn't hesitate on a pair of Irish Setters as my primary hunting boot.
If you are in need of a work boot, you could always go with a classic Redwing Moc Toe. Can't ever go wrong with a pair of those, absolutely love mine.
