I got my mare off the track as a 2 1/2 year old, she had shoes on all four. As she was still young and had not worn shoes for a long time, I decided to have her go barefoot. I did this as she was still young and hoped it would condition her hooves to being without shoes, and only wanted to resort to them if absolutely necessary. Ive never had a problem with my mare being sore or sensitive, however, I am mindful when she is on gravel and other uneven and hard surfaces. I have not had to put shoes on her at all. I have owned a TB gelding that always had to have at least front shoes on as he had always had them and was super sensitive and sore without them. I would always consider a good hoof supplement if the hoof is weak or unable to hold shoes.
