Sole Freeze was designed for the tender footed horse including competition horses. Many owners do not have the opportunity to enjoy their horses simply because the horses are tender-footed. In addition, some horses are sore after being trimmed or shod. Sole Freeze is a great product for this type of ailment. (Sole Pack Hoof Packing will also give relief in this case.) Sole Freeze is an excellent hoof hardener in just one or two applications. If your horse has a suspicious white line or thrush, then I would grab Sole Freeze to stop these infections. Do not use Sole Freeze on thrush or other infections if the infection is extremely deep into the raw sensitive tissue. In those cases, use Sole Pack instead. Sole Pack and Sole Freeze are compatible and can be used together. We often put Sole Freeze into a crevice and then push Sole Pack Hoof Packing in. Both products together give a double blast of infection fighters, and the packing keeps other debris from entering the void. Do not overuse Sole Freeze, because it can make a hoof too hard leading to easy bruising. Do not apply this product above the hoof into the hairline. If you do, wash it off immediately and apply a lotion of some sort.
