When I lived on Long Island buying a pair of boots with good thinsulate was expensive and hard to find. Now that I live in North Carolina where it's hot it seems finding a pair of boots without thinsulate, insulation, goretex, waterproofing etc is hard. After years of compressor changeouts etc I have collapsed the arches in my feet. I use arch supports to keep my arches up. My lower back doesn't hurt due to my collapsed arches while using arch supports, but they make my feet sweat to the point of getting bad athletes foot. I'm looking for a pair of boots that will stay cool. I'm tempted to drill some holes in my boots, but my employer may not like that. I figured since many of you live in even hotter climates than mine some of you may have some suggestions. Thank you.
