I am a kind of a perfectionist. If I can't do something in a proper way, I don't do it.
Well that's better than being gung-ho about it & not bothering to learn properly first. But I think being a perfectionist was part of why I started doing this in the first place - the more I learned & saw the... imperfections in the jobs of pro farriers I employed, the more I thought I could do better... or at least couldn't do any worse, even when I was inexperienced at it.
Desert is right though, that even if you have no desire to do the job yourself, learning the theories, principles & function of hooves will allow you to better understand whether your 'experts' at hand are doing a good job or not too.
but the second vet told me it is a short-time relief and talked about how important it is to find a true professionalist. I contacted a lady who is both a vet and takes care of barehoof horses in a natural way.
Sounds like the second vet may have more than a clue
and hopefully you're onto a good thing with this lady vet.
Frankly given the low angle of the coffin bone in the affected foot I doubt that barefoot is the answer
With any luck, this woman also being a vet, will know how to deal with it effectively(ask her about other nav horses she's rehabbed too), be that bare or otherwise. Be interesting to see hoof pics to go with the rads, as it may be possible to 'correct' the angles adequately with trimming, and it also depends a lot on what environment you can provide - eg. some nice pea gravel areas would help immensely & should also allow him to be comfortable bare.
But IME I agree with Patty, that it may be an uphill battle trying to keep him bare *at this particular time*. & BUT I would also be hesitant to use rim shoes in this situation, rocker, wedge or otherwise, and would instead be looking at providing added support & wedging *only under the frog*. So padded boots, Vettec, pads with casting are the first things I'd consider.
