Kentucky Horsewear's new Tendon Boots with bamboo reinforcement are made out of strong TPU with multiple ventilation holes and bigger mesh areas around the tendon area. 

The back of the boot is reinforced with Kentucky's new bamboo shield to provide extremely strong protection to the tendon area. These boots have soft natural rubber pieces around areas that need to flex to avoid any discomfort from the rigid TPU. 

The inner part of the boots are reinforced with an extra layer of TPU to protect the fetlocks in case of any knocking of the legs.
