The Coopersridge English Rear Shims are made from a Poly-Memory-Gel that allows impact zones cause by saddle or rider to be absorbed evenly, effectively removing pressure points and discomfort for both the horse and rider. The innovative blend of cushioning materials ensures the ultimate comfort for your horse by pressure dispersal, shock absorption, instant shim recovery and by reducing heat buildup. Each shim has a tapered edge that blends seamlessly under the saddle to eliminate pressure points. Available in both front and back shims to help correct a variety of saddle fit issues. The shims can be used in combination with full PMG inserts. Sold as a pair.
