I bought a pair of Irish Setter boot last fall, not the top of the line, can't remember the model. they were the cordura/leather w/gortex, no insulation. I had been on an early season hunt where I thought my feet were going to burn off my ankles from the heat and to much insulation.
When i stopped in the Red Wing Store, the gal brought out a few sizes to try, and i was telling her about the issues i had with insulated boots. She says - "hop on my pressure sensing shoe selling machine over there". I did, with much skepticism. She pointed out that i had high pressure points on the ball and heel of my foot, with no pressure at all in the arch area. She reccomended a particular insert for that problem. I looked at the price and just about laughed, but i thought, "wth", let's give it a try.
All i can say is WOW!!!! what a difference. no more hot spots, all day comfort. I wear those inserts in my insulated boots now, with the same results.
Your results may vary, but i am sold on Irish Setters only because of that particular issue being solved. I feel the boots are a comparable product to anything else out there. If i have a good experience with a vendor, i am inclined to purchase from them, all other things being equal.
PS- the Irish setter boots are pretty dag-gum nice for the price!! Wearing well, light, comfy. i will buy them again!!
