I know that for sure I have a high "instep" that I can't bar lace my shoe because it won't lace up tightly. I have a normal arch.
My BB fifth avenue's are the most comfortable with the extra support in it.
I"ll take your advice and get a insole for the strands. Such a shame because the strands are a beautiful shoe and I always get people looking and giving me compliments
Check out the above mentioned Joseph A Bank shoes.
Also, you may find the Strand golf shoe more accommodating, as it's on the 73 last. You can call Allison and have one MTOed as a standard dress shoe. Someone did that in the AE MTO thread.
