Assuming you do get the farrier 6-weekly(I'd be maintaining a pony like that little & often - no more than 4-weekly max), you desperately need a GOOD farrier. Looking at your other thread, I just assumed you were new to horses & didn't have a clue about hoof care or such, but perhaps it's bad advice from an incompetent 'expert' that has led you to allow the pony to become like that. One big reason why it's important for owners to educate themselves, not just leave it to 'experts'.
Agree with others that the horse is very likely a chronic laminitic & his diet needs careful management. What is his diet? What is his bodyshape? Does he have any lumpy 'fat pads' or cresty neck? Does he retain his coat, or shed later than others, or have longer hair than normal? I'd be consulting an equine vet too & considering getting him tested for IR, Cushings, etc. Also consider getting xrays of those feet, to learn exactly what changes have happened inside, to enable a trimmer to know exactly where they can/can't trim.
