The bottom of a horse's front hoof is the palmar surface. For the rear leg this is referred to the plantar surface.

The bottom of the horse's hoof has several different parts. The triangular shaped softer part in the middle is call a "frog". The flat part around the frog is the "sole". At the wider end of the frog is the "heel" and the outside of the hoof that the horseshoe it nailed to is the "hoof wall". At each shoeing or trim (every 6 to 8 weeks) the farrier will trim all parts of the hoof. This will keep the hoof healthy and if there is a problem forming in any part of the hoof it will be identified and dealt with immediately.

This answer has been flagged as incorrect.
The frog is a part of a horse's hoof, located on the underside, which should touch the ground if the horse is standing on soft footing. The frog is triangular in shape, and extends from the heels to mid-way toward the toe, covering around 25% of the bottom of the hoof. The frog acts as a shock absorber for the foot when it makes impact with the ground, decreasing the force placed on the bones and joints of the leg.
