TendonBoot Black 2

"I finally got to use my Equilibrium Open Fronted, Fetlock and Over Reach boots yesterday I can honestly say they looked very smart on my boy and no more sweaty legs"


Alex Dance


“We have been using equilibrium products for some time and have been very impressed. We especially love how the boots do not hold water and are so light therefore do not irritate the horses legs.”


Holly Gillott Showjumper

The Story


Complying with FEI and British Showjumping regulations for young horse classes and other restricted classes, our neat and stylish Tri-Zone Fetlock boots are designed to be worn on hind legs to protect those vulnerable areas from brushing and strike injuries.

They look great on their own or paired to match the Tri-Zone Open Fronted boots which incorporate a glossy TPU strike pad and recessed stitching.

The touch and close fastening and handy grip tab makes them quick and easy to put on and take off and our one size means that they fit most horses from 15hh to 17.2hh.

Easy to wash and quick to dry.

Lightweight, stylish and non restrictive.

The Science

Tested to the Limits

As riders, we protect our most vital areas (head and torso) with riding hats, body protectors and more recently air jackets. Rider protective equipment is subjected to extensive testing to meet standards and regulations and we believe that as a vital part of your horse, protective boots for your horse’s legs should undergo a similar testing process.

Tri-Zone Fetlock boots go through a unique 3-phase testing process giving you confidence that you are choosing the best leg protection for your horse. Materials are carefully selected to provide maximum protection but without being bulky, heavy and not make your horses legs hot and sweaty. Each individual layer in the Tri-Zone Fetlock boot is researched and sourced for their advanced technical properties and tested in an independent laboratory before it goes anywhere near a horse’s leg.

What Materials Do We Use?

EVA (Ethylene-vinyl acetate) is a material which is tough and flexible even at low temperatures. It has a number of uses in various different states and forms including in ski boots, bicycle saddles, hockey pads, wakeboard boots, fishing rods and shock absorbers in sports shoes.

The inner layer of EVA is used as a shock absorber in the Tri-Zone Fetlock boot and also has tiny holes to allow heat from the leg to escape.

The outer layer is an EVA mesh which helps disperse concussion to reduce the risk of injury.

TPU is outstandingly tough and resistant to abrasion making it the ideal material to have as a strike pad in the areas where the leg really needs protecting such as the tendon area.

What is the Testing Process?

Testing Phase 1

In the same laboratory that test standards of riding hats and body protectors, Tri-Zone Fetlock boots are safety tested to their limits for their ability to withstand concussion and penetration whilst remaining lightweight, breathable and flexible.

For concussion and penetration the testing is carried out using a custom made test rig consisting of a tower from which either a blunt hammer or a cutting blade is dropped onto the boots in a controlled fashion. The weight of the blade and hammer are fixed and different forces are applied to the boots by varying the height from which they were dropped onto the boots. Boots were hit with forces ranging from 1.25 to 20 Joules. These forces were chosen as being those likely to occur in the horse during exercise, for example when hitting obstacles or over-reaching. Here we used a carrot at 5 joules to replicate the soft tissue in a horses’ leg hitting an obstacle.

We test our boots to measure how well the boots allow heat to escape in order to reduce the risk of tissue damage. Research has shown that when tendon cells are heated to 48°C for 10 minutes approx, 80% of them die. We use several different methods to assess heat release from boots. The heat release is estimated by fitting the boots to a metal flask containing water at 45°C in a room at 20°C with no significant radiation. The surface temperature of the boots is measured using a thermal camera. The hotter the outside surface of the boot, the more heat has been allowed to escape.

If boots are constructed of inflexible (i.e. stiff) material or if boots are applied too tightly, they have the potential to restrict joint movement and cause other problems such as tendonitis. Stride characteristics and performance could also be affected. Boots need to allow as much freedom of movement as possible without compromising on their primary function of protection. We test our boots to make sure that they do not restrict the horse’s movement whilst still exceeding protection requirements. An 8cm x 1m steel pipe is set up secured to a workbench. The boots are fixed to the pipe and a 10kg weight is attached with a clip on the boot and the downward direction measured. The degree of flexibility is measured by how much the boot bends.

Adding even small amounts of weight to the end of the leg in the form of a boot significantly increases the effort the horse must make to run and can also alter the stride characteristics. Some boots can double in weight if the horse is being exercised in the rain, on wet ground or going through water. This can seriously affect stamina and performance. We design and test our boots to minimise water absorption, excess weight but without compromising on protection.

Testing Phase 2 

The boots then undergo trials by an extensive tester panel of horse owners and riders who test them for the fit, comfort, ease of use and washing to ensure we have not only a safe product but one that people can easily use and trust.

Testing Phase 3

Finally the boots go through the rigorous test of being used all day, every day on busy competition yards by teams of professional riders. The Tri-Zone Fetlock boots are worn either at home or at competitions by an array of Olympic riders, world champions and top producers.
