The Flex TPU gaiter is attached to the back of the boot shell. They are designed to keep the boots in place and allow for sizing adjustment to ensure the best possible fit for your horse. The Flex neoprene gaiters attach to the TPU gaiter, to prevent rubbing.
TPU gaiters come as part of the standard Flex Boot set when you purchase a boot, or can be purchased separately as a replacement part. When purchased separately, the TPU gaiter comes with two pre-installed rivets that are used to attach the gaiter to the boot shell.
Flex TPU gaiters are available in seven sizes that fit the following boot sizes as standard.
If your horse has unusually thick or thin legs, you may need to size the gaiters up or down respectively to improve the boot fit. Note that this means you will also need to have different size neoprene gaiters. Flex Boots can be purchased as custom boots, with larger or smaller size TPU gaiter already attached to the boot shell.
Flex TPU gaiters are made of thermoplastic polyurethane (TPU), a material that is often called a hybrid between plastic and rubber. TPU offers the flexibility of rubber, but with the strength and durability of plastic.
Flex TPU gaiters are easy to clean and maintain. Simply brush clean, rinse off any dirt and hang to dry in a well-ventilated place. Do not use cleaning products, and do not store the TPU gaiters in a closed space such as a box or in your car.
