wrong. , the frog and its matching internal structures (the digital cushion and all the supporting ligaments that tie the foot together inside) are supposed to STABILIZE the rear of the foot. That is what happens even in a BARE FOOT , IF it has strong cartilage structure inside. Thje movement in a HEALTHY hoof is nothing like that foot they show in the website. it is mostly up and out at the heel bulbs. If a hoof sheared the heels like that, that would be one VERY SORE horse from the tearing of the laminae in the heel area.When I realized that the frog splits the hoof capsule in the back to allow one side to move up while the other moves down.
Some horses however have very weak hooves and a lack of the internal structure that ties the back of the foot together. Like the one in the razer shoe website. Only a poor quality weak foot can move like the one.well they have badly misinterpreted the "basic function" of a hoof .it became apparent to me that a shoe had to be designed to coexist with this basic function.
Not flexing like that.Itīs obvious that a hoof must flex to stay healthy.
