STS stands for "save the sheep" as it is a synthetic super soft sheepskin-like material.
The TRC Vento brushing boots from Verdeus is designed to emit heat and emits cool air, making the horse's legs maintain a consistent and well-tempered temperature. Leg protection protects against impact and shock due to the fact that they are fitted with anti-shock carbon.

Like all equipment from Veredus, these protection has a great fit and closes with a sturdy Velcro (Double Velcro). The leg protection will be in place throughout the training.
