Looks like you have a grade 1 club foot syndrome possibly grade 2. http://www.nanric.com/grades_club_foot_syndrome.html
The club foot is fairly simple to manage. Leave enough heel so there is an equilibrium between the deep flexor tendon and the toe wall. Take an after shoeing x-ray and a x-ray before the next shoeing. If the coffin bone is at a higher angle before the next shoeing, the angle of the foot was most likely lowered too much the previous trimming. If there is a constant dish which can’t be trimmed out (without rasping the toe wall thin), the heel was most likely lowered too much.
The low foot is more difficult. For what ever reason, more pressure is on the back of the foot. Add to that the digital cushion may not be developed properly. There’s many ways to mechanically set the foot up. Generally, I will add a rim pad plus a perforated pad with a soft pour. After a shoeing there will usually be a good amount of sole depth. After a few shoeings you should be able to maintain a few positive degrees in the foot (+/-)
Management, Farriery, environment, hoof quality… will all dictate the overall success.
