ORIGINAL EQUINE COMPRESSION SOCK .What is graduated compression? It is a type of compression that is applied to the muscles, where there is greater pressure at the extremities and then gradually easing off at the top of ones limb and again at the top of the torso. This process forces fluids that tend to pool back up and out of the limbs and back into circulation. Is there any proof that gradient compression will help my animal ? We have done many trials with HIDEZ over the years.
