Eggplate

Hoof motion (Full) 2020


Nature originally intended horses to have four toes, then three and over time it has been reduced to one toe. That is evolution.

The horse is an escape animal, i.e. in case of danger it runs away in the opposite direction to the danger, straight ahead and as fast as possible. This is the horse's great strength. In curves and especially in tight radii, things look a bit different. This is where our invention, namely the Eggplate, comes into play.

Eggplate - one step ahead of evolution!

With today's use of horses in the various equestrian sports, it is so that a lot is demanded of the horses and they have to work mainly in curves. Horses must therefore be able to master very tight radii as quickly as possible. My goal is to be able to give the horse the comfort that it feels as good in the curve as if it were running straight ahead. We often find, especially with older horses that have been used a little more in sport and may have a health history, that lameness becomes apparent primarily on the volte and only secondarily when walking straight ahead. With the Eggplate we have developed something that gives the horses the same comfort in curves as when walking straight ahead. The proof is that when we x-ray the horse standing on two legs we see that the joint gaps remain parallel. When we lift one leg, the joint space normally becomes narrow on the outside, but with the Eggplate it remains parallel.

We have created a slow motion video. It shows the horse with old eggplates, without iron, with fullrocker shoeing and finally with new eggplates. We filmed each jump and landing. We would like to take this opportunity to thank Thomas, Valerio, Jeremy and Rachel for their active support. We have also recorded our findings.

X-ray images were also taken for each fitting. Below you will find these with our analyses.

Findings

  • Fitting: Eggplate old
  • Fitting: without iron
  • Fitting: with full rocker
  • Fitting: Eggplate new
At first at a trot, then jump / landing. The horse moved most comfortably overall.
Horse behaves very sensitively and with little room to move, increased blows, strong static friction and sinks relatively deep. The length of the jumps is significantly shorter (1.30m shorter trajectory) and close to the obstacle.
More comfortable than without iron, hoof still sinks relatively deep into the ground, but much better than without iron. Horse is certainly grateful for hoof protection.
Less sunk in, greater static friction, joint gaps parallel, position remains optimal, all in all we can say that Eggplate is very useful and keeps its promise.

We have made and analysed x-rays of these experiments. These are standard pictures also in sand under tournament conditions. The respective pictures are listed below with the corresponding comments.
