If a horse has thicker than normal legs, or a lot of feathers, the pastern strap might not be long enough to reach around the leg properly. On pony size Flex Boots and smaller horse size boots the solution is to change the TPU gaiter to one size larger. But on 145 and 150 size boots, this is not possible because they already have the largest available TPU gaiter on them. This is when a pastern strap extension piece comes handy. It is attached to the normal pastern strap with two flat rivets, and then fastened to the ball rivet on the opposite side of the pastern strap as normal.

One size, fits size 145 and 150 boots.

Sold and priced in packs of two extension pieces and four flat rivets to attach the extensions to the pastern straps.

The pastern strap extensions 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.

Care instructions

The TPU material keeps its elasticity and lasts longer if the product is in regular use. After use, simply rinse off any dirt and hang to dry in a well-ventilated place away from direct sunlight. Do not store the TPU parts in a closed space such as a box or in your car. All TPU parts can be brushed clean and washed with water. Do not use cleaning products.

Flex Boots are designed, tested and manufactured in Finland.
