Some are used to soften dry, brittle feet to make them more flexible and less prone to cracking while others are intended for hardening to keep feet from becoming too soft in wet conditions. Some aim to do both — by keeping the natural moisture in and excess moisture out.
The hoof wall is made of connective tissue — similar to skin, but much harder, more like human fingernails. Like fingernails and skin, hoof horn (which is made up of tiny hollow fibers) must contain a certain amount of moisture to remain resilient and pliable.
