The RIB nail is designed for increased traction. The head has a normal rectangular form that fits firmly into the fuller, but is extended and ends in a wedge-shaped point. The head fits into the shoe as normal, but the top of the head forms a wedge to protrude above the level of the shoe to aid in traction. The RIB-nail is designed for horses that require additional grip with every step - for example trekking ponies in rough and variable terrain.
