A footpad (sometimes spelled foot pad) in the context of equine care and farriery refers to a protective, shock-absorbing material inserted between the sole of a horse's hoof and the horseshoe. These pads are typically made of leather, plastic, or rubber and serve various therapeutic and preventative purposes for the horse's hooves and lower limbs.
Purpose and Function
The primary functions of a footpad include:
- Protection: Shielding the sensitive sole of the hoof from bruising, impacts, and abrasive terrain, particularly on hard or uneven surfaces.
- Cushioning: Absorbing shock and reducing concussive forces on the hoof and lower limb joints, which can be beneficial for horses with existing lameness issues or those performing strenuous activities.
- Support: Providing additional support to the sole or frog, especially when used in conjunction with impression material or packing to distribute weight and pressure more evenly across the entire hoof structure.
- Therapy: Used as part of a treatment plan for various hoof conditions, such as sole bruising, thin soles, navicular syndrome, laminitis, or other causes of chronic foot soreness, by offering comfort and reducing stress on affected areas.
- Maintaining Moisture: When used with specific packing materials, pads can help retain moisture within the hoof capsule, which can be beneficial for horses with dry, brittle, or cracked hooves.
- Prevention: Can help prevent stone bruises and other penetrating injuries by creating a barrier between the ground and the sole of the hoof.
Types and Materials
Footpads come in various designs, thicknesses, and materials, each suited for different applications:
- Leather Pads: Traditional and breathable, offering good general protection and comfort. They conform well to the hoof's natural contours.
- Plastic/Polyurethane Pads: Durable, waterproof, and available in different thicknesses and durometers (hardness). They are often preferred for their longevity, ability to protect against moisture penetration, and customization options.
- Rubber Pads: Offer excellent shock absorption and flexibility, making them particularly useful for horses needing significant cushioning or working on very hard surfaces.
- Wedge Pads: Thicker at one end, these pads are specifically designed to alter the hoof angle for therapeutic reasons, such as addressing contracted heels, specific lameness conditions, or balancing limb conformation.
- Rim Pads: Thinner pads that primarily protect the white line and outer sole, often used to prevent stones or debris from becoming lodged between the shoe and the hoof wall.
- Full Pads: Cover the entire sole of the hoof, providing comprehensive protection and support.
- Bar Pads: Feature a raised bar or section across the frog region to provide support and lift to the frog and caudal (rear) part of the hoof.
Application
Footpads are fitted by a farrier during the shoeing process. After the hoof is meticulously trimmed, balanced, and prepared, the pad is accurately cut and shaped to match the sole of the hoof. The pad is then placed directly against the sole, and the horseshoe is subsequently nailed over both the pad and the hoof wall. Often, a pliable packing material (such as silicone, impression material, or oakum mixed with pine tar) is placed between the pad and the sole. This packing fills any voids, provides additional support, further absorbs shock, and helps prevent debris accumulation within the pad.
Considerations
While highly beneficial, footpads must be applied correctly to avoid potential issues. Improper fitting or prolonged use without proper hygiene can trap moisture and debris against the sole, potentially leading to bacterial or fungal infections (e.g., thrush) or compromising hoof health. Regular removal and cleaning, along with careful monitoring for any signs of infection or discomfort, are crucial when pads are in use. The decision to use pads, and the type of pad, is typically made in consultation with a farrier and veterinarian, based on the horse's specific needs, environment, and activity level.
