Good sturdy well fitted boots. With new bioots, put on with good cushion sole socks, then soak the boots in water and walk in them until they're dried That will stretch the leather amd mold it to your feet. I've never had a blister or a corn. I have EEEE wide feet, so I like a Munson Last type boot. Second, at least three pairs of good socks. Change several times a day, and they'll dry tied to your pack harness. Don't forget toilet paper. Leaves just don't do it, and there's always the possibility of poison ivy. A GI entrenching tool. With a sharpened edge can be used as an axe if necessary, and perhaps a 15 minute highway flare. They'll start a fire under almost impossible conditions. Average walking speed over rough ground is about 2 mph, however 3 mph on roads is easy. The Roman mile was 1000 paces, that's 2000 thirty inch steps. A space age blanket makes a good ground sheet, and the heat reflecting side will reduce body heat loss under adverse conditions. About 8 drops of iodine will purify a canteen of water, BUT you must learn to practice water discipline. The trial hike sounds like a good idea. Good luck, and I hope you never have to use the emergency kit!
