For me, trail runners work for day hikes, but UL "boots" like the Montrail Namches are more my preference. For Winter/ early Spring hikes, where there is a lot of water and mud on the trail, I wear some "heavier" Merrell Pulse II Gore-Tex mid-high boots that are a whopping 2lbs 12oz pair.
The main issues are my weight, the pack weight (always trying to reduce both), trail conditions, and my aging feet. Most of my hiking is on the western slopes of the Cascades with plenty of rocks, mud, and streams flowing right down the trail when there is snow run-off. Stone bruising is my main complaint with lighter shoes.
The scene below is a local trail in early June with snow fields 1500 feet above. Rough in any weather, and 35F flowing water at this time of year. Far different than than a nice little roller-coaster trail with a carpet of forest duff where you can hear your footsteps "echo" in the low density earth. Envision doing a face plant going down this mess!
