The LeMieux Pro-Sorb Plain Dressage Square features an effective system which allows simple adjustment to the fit of a saddle through the use of memory foam inserts. Not only will this improve fit and saddle placement, but will also reduce pressure on the horse's most sensitive areas. It allows the optional pads to be inserted to lift either the pommel or cantel of the saddle, correct bi-lateral imbalance or create a layer of shock absorption for the horse.
