Leverage Testing of Hoof



Gene Ovnicek, an experienced farrier and hoof researcher, has developed a variety of commercial hoof care products since the mid-1990s, including the Krosscheck device. This device is a plastic block that is temporarily secured in place to the sole of the horse’s hoof. It has a heavy plastic wedge dial which can be rotated to allow elevation of the ground surface of the medial, lateral, toe or heel of the horse’s hoof.

The behavioral response of the horse when asked to stand on the block (with the dial placed at the various settings) is taken as an evaluation of comfort.

In my opinion, the use of this device is highly subjective but may add some diagnostic value to a lameness evaluation. The results of testing need to be interpreted carefully and should not be used as a substitute for a thorough lameness exam by your vet.

Possible Diagnoses


This device might provide additional information to a vet and farrier, but should be used in conjunction with other diagnostics.


In my opinion, it is an oversimplification to believe that a definitive diagnosis can be reached using this device alone.
