I have a couple pairs of the Kennetrek mountain extremes and also have a narrow foot. The two models I have fit like a glove but take a little while to break them in. I am a happy customer because very few boot makers have a model narrow enough to fit me well. I’ve tried multiple ones in the past including schnee’s and crispi. The Kennetreks just fit me like they should but they are a heavy/stout boot that is excellent in rugged, mountainous terrain. Probably could find something lighter and less stiff if your terrain isn’t severe.
