15 narrow here, I share your pain.
I have heard good things about Parker's, but have never worked with them.
I went custom route a few years back and have never looked back. Jumping off for calf is around 900.00 for most custom shops.
For hard to fit it's totally worth it, and comfort and quality will be superior to anything you get off the shelf.
I did a lot of research and found a couple places I like and have stuck with them. Not local so not really much help there.
But I will say if you go custom, do your research and go in knowing close to what you want. For me toe shape was important and each maker has slightly different style, because that piece is hand carved.
Good luck!
