Though the temps I hunt in are much colder, I've used my boots from temps from 40 above to 40 below. Cabela's Inferno (2000 grams thinsolate). I picked up a pair of socks that are specially designed to wick the moisture away from the feet which work esp well when it is on the warmer side outside or it's a day when I'm going to do alot of walking. The boots are gortex and allow the moisture to leave very well. They are lace up pack boots with a fairly high arch so they are great to walk in but they are also real good when sitting in a stand for hours in -30 or so weather. They're in the $150 range and I believe well worth the price. I find my feet sweat more and it is alittle more difficult to walk all day in my rubber hunting boots (though when hunting in some swampy areas the rubber boots are the way to go). I suppose your hunting situation will dictate the way you choose. Best of luck finding the right boot because for me, cold or sore feet truly take away from a great hunt.
