Well alrighty then, lollol.
1. Possible abscesses - that would mean soaking in warm water and Epsom salts and it would mean NOT packing the hoof until the abscesses blow:(
If ever there was. ďYes I guess notĒ moment, this is it.
IF it is safe to pack the hooves (no abscesses) We used VetTecís Equithane CS liquid hoof pack on Joker for about eight months. ďCSĒ = Copper Sulfate. https://www.vettec.com/en-us/equi-pak-cs-210cc-pour-pad
This stuff is awesome and I highly recommend it. The horse does have to stand well for an extended period but at least the pour in sets up in only a few minutes.
We stopped using it because, like everything else thatís been tried on his hooves, it became counter-productive.
I offer this ^^^ as an alternative to full leather pads. Dirt can get under the leather pads from the back of the shoes and you have no way to clean it out.
My thought is the pad either has to completely seal the hoof (like the Equithane) or the pad could be a partial wedge pad, that fits all the way around, under the shoe, but leaves the sole exposed and you would still be able to pick his hooves.
The wedges, however, may not be a good application for whatever they think is wrong.
You did say the new farrier is a vet tech. Hopefully she has some new technological magic in her tool box to help your horse:)
