These open front tendon boots feature a hard shell that conforms to the horse’s leg protecting the tendons and fetlocks from overreach and sand burns while allowing more heat to escape than a boot that seals in the entire leg. Hard shell is lined in neoprene and measures 8.75” from top to bottom. One size fits most. Boots are sold as a pair, one left and one right. Free returns within one week of delivery, after one week returns will be at buyers expense and subject to a restocking fee.
