Abstract

The present study investigated accelerations of the front and hind hooves of horses comparing two different shoe types. A standard steel shoe, with studs, pins, and in some instances with toe grabs, was compared to a steel shoe covered on the bottom with a layer of polyurethane. Four horses were used; they trotted in hand on an asphalt track at their self-selected speed. The results showed significantly reduced decelerations during the stance phase with the polyurethane-covered shoes (10th percentile median steel -2.77 g, polyurethane -2.46 g; p = 0.06) and significantly increased decelerations in front hooves compared to hind hooves with steel shoes (70th percentile median -1.04 g front hooves, 0.12 g hind hooves, p = 0.04). Horses trotted faster using longer strides with the polyurethane-covered shoes compared to the steel shoes. The results show that effects of shoe types should be investigated simultaneously in front and hind hooves, and that PU shoes may aid in reducing the overload present in the front limbs of horses.
