I switched to unlined leather boots recently and find my feet are generally much drier and more comfortable, except in constant heavy rain.
I think it depends on your feet to some extent and how thick the boots are. I have a couple of pairs of gore-tex shoes which are fine but my feet sweat like mad when hiking in heavy lined boots. Other people have no problems.
