IMHO, there are as many ways to interfere as there
are ways to fix it. You didn't metion HOW your horse was
interfering.
In my experience, sometimes a horse will begin to
interfere because his farrier has 'leveled' his feet and 'leveled' his feet, and
'leveled' again, when he (the horse) really wants his feet just off of perfect
level.
Twice, with high mileage horses, I had to pull
shoes, ride barefoot enough so that the horse wore his feet the way HE wanted
them, put the shoes on without trimming too much, and the interference went
away.
Sometimes we think WAY too hard about things when
it isn't that difficult a problem. Just food for thought.
