I use to work at a big name saddlebred farm and they had their horse padded like the ones on the site. I had seen and helped their farrier, and I will give them this much credit, they never did anything to hurt the horse. They never used anything other than shoes and leather pads to get the gait they wanted.
On the other hand, I watched SO many shoes, pads, and hoofs go flying across the riding arena, I finally got disgusted and had to quit. Some of these horse hooves would break off so close they would be sore for weeks on end. To begin with they left their feet really long so they could "hold" the shoe to begin with, then added the metal bands to help hold the shoe. Instead of trying to treat the hoof and give the horse a chance to heal, they would have a farrier out immediately to build the hoof back up with acrylic and put the shoe right back on. I felt so bad for the poor horse because you knew they were in pain after that shoe and half their hoof went flying off. Then to top it all of, within a week or two the scrylic would break off and the same thing would happen ago, this is now why I am staying away from TWH and Saddlebreds. Between this and the soring issues that are going on, they have ruined the two breeds for me.
