Hey Darkw, if you haven't already get the Mobe's see my above post I have a similar foot and the Scarpa worked really well. I still needed to do a little work on the Mobe but far less than I would have had to do on the Factor to fit my EE/EEE and super high arched foot in (the factor has a much lower instep area. Anyway so far all good. Much snugger than My Spirit 4's of the same size which did start to get a bit big in the heel, though I did a pretty good job of filling that up with some creative padding (former life as a boot fitter helps). Anyway I hope that helps.
