Weather makes the final choice for me. Merrell hiking boots if it's not too nasty, my cold weather hunting boots if it's bad. Saw some guys in tennis shoes, most seemed to be in some sort of trail shoes. Main thing is make sure they are good for a long walk/run/hike ahead of time. That is not a good day to get blisters.Any thoughts on footwear? Trail running shoes, trail hiking boots, pointy toed fence-climbing cowboy boots, Flip Flops??????
