This is a complete crap-shoot...but do you by any chance knit as well as sew? Because one of the great things about knitting is you can custom-fit socks for non-traditional body shapes. For serious, I have hobbit feet: wide and short, and I always find socks dig in too much as well because my ankles were apparently swollen from lyme disease. But I digress. Anyway, I am now in the process of fine-tuning the hand-knit sock process. It is addictive and delightful.

If not maybe you have an awesome friend who could hand-knit you hiking socks? Or perhaps you could commission a pair?
