While I am not over-cautious or over-reactive, I am pro-active which means that if I genuinely think a change in my routine will help my horses, I am willing. Speedy has been in bell boots at times, mostly when he was wanting to pull shoes, but he's never really needed leg boots.
When I say he hasn't needed boots, it's because he doesn't interfere. Lately though, I have been using leg boots since I am asking him to do more lateral work and a more collected canter. And since we had that recent bout with forging and sore heels that caused him to be lame, I decided that he need some protection, so we now have a new "normal."
