I have a coming 4 year old mare that I use splint boots on. She does not mind those and I am planning on purchasing some PC boots for her this spring. I think that boots are a good idea to use but not necissary to have. They are mostly used for horses that are competing and that closley placed legs because sometimes if a horse has naturally close feet and they are running or jumping etc, they will clip their hocks and can become injured. I would suggest boots for anyone that is competing, or training to compete, and definitely anyone who has a horse whos front feet are a little too close knit. Hope this helps!?
