Since I tend to only go very early or late in the season I use Muck boots, and like them, but they'd be too hot for warm weather trips IMO. Not much ankle support but dry and a nice lug sole w/steel shank. All is good till you go over the top, and that'll happen. When that happens a sense of humor helps. I'm not sure there is a "perfect" boot.

I had the OTBs till they finally rotted away. But I did notice the mess let in fine grit that added to wearing away the neoprene socks I used in the heal area. i also noted the neoprene booties seemed to stay wet and the evaporative cooling effect made for cold feet, equal to just wet footing it w/wool socks IMO. I tried Sealskins and pretty much the same, foot sweat and/or wet outer layer made for cold feet.

I had a visit from a pair of Q park rangers once and noticed they wore what I'd call '70's era Army Jungle boots, part leather, part nylon, and they had cut a few holes into them to help with drainage. It was early Sept and they were wet footing it. Probably very cheap at a Army Surplus store.

IMO even if you get wet feet and it's cold, it's not too bad as long as you have dry socks and shoes for camp. You may need to dress your torso a bit warmer. I'm pretty sure that's what the park rangers were doing.
