Im sorry II but i think you need to concentrate on narrower shoes they are wide enough already. It is really offputting when your feet slide around unless you get excrutiatingly small shoes where you have to scrunch your toes up
Trying to plod up hills every day slightly faster than the day before
Turbo I think the "Ultimate Fell Racer" may well be what your looking for.
I also have a narrow foot and find the X-Talon too wide for when Im contouring ( though is ok when on mountain paths)
The " Ultimate Fell Racer" very light, sticky rubber stud sole, low profile and a narrower fit........were on with it
