Actually he was shod for the years we couldn't get the crack to grow out. We pulled his shoes and, through the help of people here and the links they posted (Hours and hours of reading) I started doing my own barefoot trimming. He hasn't had shoes on at all since the first picture. I had him shod and that crack opened up like a canyon. I pulled that set and haven't looked back. I do my own trimming and ride him in Renegade hoof boots now. We are both much happier.
