Have you tried Adidas boots?And I feel your pain, only amplified. Skinny ankles, normal heel, EEE-wide front foot, high instep, high arches, collapsed front foot valves. Suffering from searing front foot pain after only a couple hours of riding. Got custom made footbeds and wide Photons and that made things better, but not good. Have bought Katanas to replace my Cartels to alleviate instep pressure but haven't had the chance to try it yet. Next step will be aggressive modding of the liners.
If it doesn't work out I'm seriously going to consider the hardboot route because I'm getting desperate (hope BA doesn't see this because I know he'll shit on me😅) - bye-bye board feel. Or at least that super-weird hydrid boot, Ground Control from Deeluxe.
