I have used the Simple Hoof Boots on all three of my horses for the last 4 years. I run my horses barefoot, but when we go up into the Tetons, I always boot them. There isn’t anything we haven’t experienced in our gorgeous mountains. We have been through deep rivers, sucky mud, slick ice and snow, smooth granite slabs, rocky trails and greasy, muddy slopes. We have never had a Cavallo boot come off or had one wear sores on my horses feet. Our terrain is rough, but incredibly breath taking. I’m 64 and depend on my horses to get me to and from these incredible mountains safely. Thanks to the boots, I never have to worry about walking out 10 or 15 miles because my horse lost a shoe. Thanks Cavallo, for a hoof boot that even a more seasoned (old) lady can get on and off with ease.
