For the cross-country phase, the rider usually uses similar tack as for the show jumping. However, cross-country boots are used for extra protection, to help prevent injury if they were to hit the solid obstacles. Most horses that wear shoes are also fitted with horse shoe studs, to prevent slipping. At the upper levels, riders may also apply a grease or lard to the front of the horse's legs, to help the horse slide over fences if they hang a leg. Riders also tend to color-coordinate their cross-country tack to their colors. For example, using the same color saddle pad and tape for their boots, to match their shirt and protective vest.
