Metal horseshoes have been used for approximately 2,000 years to protect hooves on hard surfaces and provide traction. Nailed-on metal shoes restrict hoof capsule expansion during weight-bearing, potentially altering digital blood flow and proprioception. Poorly fitted shoes cause significant welfare harm through pressure, nail prick, and gait alteration.
Unshod hooves expand significantly at the heels during weight-bearing, facilitating blood pumping in the digital cushion. Research by Bowker and others shows that horses with adequate digital cushion development have better hoof mechanism and perfusion. Barefoot hooves wear and callus naturally on appropriate terrain.
Horses transitioned from shoes to barefoot management often show initial foot soreness from inadequate hoof development. Hoof boots used during transition provide protection and comfort. Fully transitioned barefoot horses on appropriate footing show normal locomotion. Pain assessment during transition is a welfare priority.
Comparative studies show that well-transitioned barefoot horses on appropriate footing perform comparably to shod horses in many disciplines. Barefoot management may reduce navicular disease and laminitis risk. However, horses working on hard artificial surfaces may genuinely need hoof protection that shoes or boots provide.
Regardless of shoeing approach, regular farriery is essential for welfare. Long, neglected hooves cause pain and gait abnormality. Farrier training standards, veterinary oversight, and owner education in hoof care monitoring prevent welfare failures from inadequate hoof management.
The barefoot vs. shod decision should be made individually based on hoof conformation, workload, footing, and health history — not ideology. Veterinary and farriery input, regular locomotion assessment, and monitoring for pain indicators (lameness, withdrawal, behavioral changes) guide welfare-positive hoof management decisions.
