The Easyboot Glue-On shell has been developed as a high performance boot and an option for horses in speed and long distance events. The light weight shell has thin walls that allow the boot to stretch and form to the hoof. The end result is a seamless one-to-one fit that resembles a second skin over the hoof. The Easyboot Glue-On is the closest hoof boot option to the barefoot horselight weight, no hardware and a seamless fit. In order for this boot to work properly, it must fit snugly, the foot must be dry during application and the glue-on process must be carefully followed. This boot is perfect for the following situations: Pack trips Multi-day rides Endurance events Competitive trail rides (Most CTRs do not allow boots that come above the coronary band.) Speed events, such as barrel racing Any circumstance where the presence of hardware is a concern. These boots are meant to be disposable, used once or twice and then thrown away. Glue left on the inside of the boot may affect performance. We do not recommend that a boot be left on for more that ten (10) days in a dry environment or five (5) days in a humid environment.
