The Flex Boot has five ball rivets attached as part of the fastening system; the TPU gaiter that goes around the pastern has one ball rivet at the front for fastening the TPU gaiter strap, and there are two ball rivets on each side of the boot for the back strap to attach to.
The ball rivets are secured with screws on the inside of the boot and with washers in between each rivet and screw. We recommend that you check the rivets on your new product, before first use and then at regular intervals to make sure they remain tight expecially during big temperature changes.
If your horse has a narrow gait and brushes against the ball rivets, we recommend that you change the inside ball rivets to flat rivets.
Sold as a set of five. If you are ordering replacement rivets for your boots, please make sure to also order the correct washers to go with them; the washers are sold separately and not included with the rivets.
