on your age, biomechanics, terrain, time on the trail and load carried, among a host of variables.
For east coasters doing the white mtns, the green mtns, the adk's, the catskills, you should wear a scarpa sl-m3 type boot. if you don't you run the high probablity of a broken, badly sprained ankle, bruised soles of your feet. that is the reality. when i am on the west coast, e.g., jmt, tuolomne, pct, it's easy going for the most part. so if you aren't out for days, solid trail runners can do it. but, if you blow your feet out for 12 ounces don't forget who made the decision. without feet i don't care if your golite pack is filled with helium and weighs in at -2.56 grams, you ain't going anywhere. that's 45 years of trekking experience in a lot of countrys speaking. not advice, just an observation.
