Hi Have the Professional's Choice Ballistic Overreach Boots in size medium and they seem to fit around my horse's feet just fine. However, they are always getting stepped on and ripped up in the back underneath. Does anyone know if there is a "shorter" overreach/bell boot out there that might work better for me? The size small, according to Prof. Choice's website, is only a smaller circumference, not a shorter length. Or maybe I'm doing something wrong?? Any suggestions or advice would be much appreciated! Thanks!
