Horses with pain during the early stance phase of the trot will not allow the pelvis to drop as much when the lame leg is weighted, trying to avoid extra weight on the painful leg. Subsequently, the pelvis will not fall as much downward when the lame leg is bearing weight as when the sound leg is bearing weight.
In addition, the musculoskeletal foot arch and sole cushion of the elephant act in concert, similarly to the horse's cushioned frog and hoof [6] and the human foot. [29] In the elephant, the nearly half- cupula -shaped arrangement of the bony elements of the metatarsals and toes has interesting similarities to the structure of the arches of ...
The sole has a whitish-yellowish, sometimes grayish color. It covers the whole space from the perimeter of the wall to the bars and the frog, on the underside of the hoof. Its deep layer has a compact, waxy character and it is called 'live sole'. Its surface is variable in character as a result of ground contact.
The modern name "caltrop" is derived from the Old English calcatrippe (heel-trap), [6] [7] such as in the French usage chausse-trape (shoe-trap). The Latin word tribulus originally referred to this and provides part of the modern scientific name of a plant commonly called the caltrop, Tribulus terrestris, whose spiked seed cases resemble caltrops and can injure feet and puncture bicycle tires.
Horses with a high weight-to-foot-size ratio may have an increased chance of exhibiting symptoms of navicular syndrome, since the relative load on the foot increases. This might explain why the syndrome is seen more frequently in Thoroughbreds , American Quarter Horses , and Warmbloods as opposed to ponies and Arabians .

A small foot is less capable of diffusing impact stress with each footfall than a larger one. On hard footing, the foot itself receives extra concussion.
