Thanks all! I usually shoe him in the warmer months since he does get sore, esp on rough surfaces. Used to use pads as well but now I rarely ride on gravel so he is pretty good with just shoes if I stick to the nearby trails which are soft. I do not shoe in the winter as I rarely ride once the snow falls, and I don't want ice building up on his shoes.
We have tried wedge shoes with him, to bring the heel up, but once the shoes are off he goes back to his normal under run heels. Have been thru .. I believe this is the 4th farrier, and he seems the best with him... he has poor feet. I am hoping if I can keep his sole ( and of course everything underneath!) tougher he will not get so footsore on the ice in the winters as well.
