Lots of good advice here. So I'm not a farrier, but am learning to trim my horses then my farrier doesn't have to come out as often and my "grow foot super fast TB" doesn't flare on me.
You asked about transitioning to barefootedness - so happy to hear you want to go that way!! Here are my suggestions, pull those shoes and get a pair of boots. I think someone suggested Pete and / or Jamie. There are some great sites online to search for natural trimmers -hopefully your current farrier does the "natural" trim, sometimes called the mustang roll. There is a difference between a pasture trim and a natural trim - where the natural trim in my experience is much better. I just transitioned my TB from shoes to naked hooves (took almost 2 years because I didn't have the right trim). It took me three farriers before I found the right one. And since my guy grows hoof like it is going out of style, flares at 3 weeks, I had to learn how to maintain what my farrier is doing. It can be a long process to transition, but is SOOOO worth it in the end!
Good luck and keep us posted!!
