No, I was interested in what you liked, which I assumed was what you thought we should be using LOL. I drive a single and although I started a new young horse in the last couple years, I have driven advanced in the past. I have never had a horse come in with an injury to the front cannon bone of a leg. If I have had something they have grabbed a heal where a bell boot got torn off, and I have seen marks on the hard shell of the sides of the boots, but I honestly have never found a mark or injury on the 1" space or so on the front of the leg with the boots I am using.
FWIW, I NEVER train with any kind of boots at home, and for years I used borium drive in studs that stayed in all the time. I think the use of boots on a continuous basis actually leads to a weakening of the legs and leads to more injuries if anything, and the vets I have used agree. Also, in my 17 years, knock on wood, I have never had a horse injury of any significance with any of the horses I have driven, so I guess I have tendency to think if it ain’t broke, don’t fix it… The only time my horse wears boots now is on a marathon at a CDE. I put on the hard shell boots and bell boots all around and head on out.
