The Flapper takes a half shoe fitted into the recess in front of the heel portion of the pad. This results in the dispersal of pressure and concussive force on the horse's heel area. The frog and bars are designed to have "passive" ground contact and are supporting structures. The Flapper is useful in treating: a) general bone and joint soreness, b) weak or contracted heels, c) navicular syndrome, d) ringbone, e) sidebone, f) quarter or heel cracks.
