Well, I think I am not understanding what you mean by trail runner now - all trail runners have low ankles. They are running shoes for the trail. Not mid height boots.

Goretex for a trail runner makes little to no sense to me. Then again, Goretex in shoes in general makes no sense to me, except in winter boots. Perhaps an indicator of where I hike (the mild and usually on the dry side Sierra Nevada) that I much prefer more breathable non-goretex shoes to any boot.
