If you would be willing to travel to Lexington, I'm pretty sure that Bob Mickler's will do custom orders for at least one, maybe two of the brands you mentioned, though you would think they dealt only in Ariat from looking at the website. Give them a ring!
I got two pairs of Dehner's there, one dress, one field, they are both perfect and I have some unusual fitting issues. They do a great job. Plus, lots of other yummy stuff that Mickler's (which I love by the way) doesn't carry. Tack Trunk is much larger and closer to you.
Anyone have current recommendations for places near Columbus Ohio to get measured for custom Dehner's? Tack Trunk or go to Lexington?
Dublin Tack Shoppe is a Dehner rep. Equus Now measures for Sergio Grasso and I'm pretty sure they measure for Vogel too, so I'd bet they could help you out with Dehners. Mary Ann at The Tack Trunk is great as well.
