Tapered wedge closed cell foam. Use to fill the small gap or space behind the horses shoulder and under the front of the saddle. Shims are recommended to support, adjust for a better fit, or promote a more level fit. Place shims just under the front of the saddle and on top of the saddle pad as needed. Move forward or back to give more or less lift.
These shims can be very helpful on a horse who has underdeveloped or atrophied muscle behind the shoulder or on a horse with a very flat back to keep a saddle with too much rock from tipping forward.
This is one package of 3 shims. 1) 3 3/4 24 1/4 and then 2) 5" x 24 1/4
