I rodeoed all over the US and Canada. With my horses shod, but sometimes when the shoer had a bad day, lazy, etc. and my horses were off, it cost me and ultimately my horses soundness. So....and it won't work with every horse, and depending where you are racing, I have been trimming all of my horses, myself, for 6 years. I am not perfect and have used lots of advice, and all the knowledge I had, about getting that foot level, when I was keeping Thelma shod. Of course, it used to cost $25 to shoe one in NM, but now OMG, it is so expensive. But, thankfully with the help of FM 11, because it has Cayenne pepper in it, it not only speeds up the circulation in the feet, causing wonderful growth. It is very beneficial to my horses, as they continually grow great foot and I trim about every 2/3 weeks. So unless it is really dry, they have good enough feet to run barefooted, all the time. One mare is very tenderfooted, she wears Soft Ride, when it really wet, or we are walking on rocks to get to an arena. Otherwise, I trim her 2 weeks before a big show, and then just keep them pretty and neat, before. I (where is the wood), have had no slips, barefooted.
