In order to prevent extraneous matter from adhering to hooves, expel any extraneous substances adhering thereto and assist the movement of the animal, a horseshoe-shaped insert body 1 is formed by a bent-over toughly elastic strip of material, the bend forming a tube 2 which contains an air chamber 5 of high resistance to counter-pressure immediately followed by air chamber 5' of low resistance to counter-pressure. The insert body has preliminary cuts 7 which, after being cut open, enable the width to be increased and also reduced. Closures 4 in the tube 2 separate the air chambers 5' of low resistance to counter-pressure which immediately follow them and of which the end parts 6 are open. |
