Front Inserts: Made from visco--elastic foam (also called "Memory Foam", the front inserts are strategically placed to fill the dip beneath the withers. The high techno foam is strong enough to sustain lift, yet pliable to provide seamless build-up only where needed and absorb the motion of the shoulders in a way that is most comfortable for the horse. Rear Inserts: These are made from Plus Foam an stop the saddle from "rocking". The inserts will provide a lift of about 1/2 to 3/4 inch.
