I have done a little endurance as time allows (usually I am the one with
the stethoscope waiting for you though) and my horses have done great. It
made all the difference in the world with my guy who broke his neck as a
jousting horse. I thought his stumbling was his neck and it turns out it
was his feet (he has tiny coffin bones on xray). Once we put his breakover
back for him....the stumbling stopped and his stride lenghthened a great
deal.
Sounds like you have a great farrier...don't let him go. Check out the
farriers website at www.horseshoes.com. Trail Blazer has been running a
bunch of articles by Nancy Loving and one by me on the use of balanced
trimming in the endurance horse. You might want to check those out
too...my article on Gene's stuff was in last July's.
