Can Saddle Shims Correct a Fit Problem?

Saddle shims can help fine-tune a modest, clearly identified fit imbalance, but they cannot make a fundamentally wrong tree fit correctly. The best use of a shim is targeted and purposeful—for example, supporting a changing topline—not simply filling every available pad pocket.

Good Reasons to Consider Shims

Shims may be useful when a horse has temporary muscle loss, mild asymmetry, or a small area that needs support while conditioning changes. They can also help level a saddle when the tree is otherwise a reasonable match. The cause should be identified before material is added.

When Shims Are the Wrong Answer

If the saddle is substantially too narrow, too wide, too long, or has the wrong bar angle or rock, padding usually redistributes the problem rather than resolving it. Adding thickness under a narrow saddle generally makes it narrower.

Use the Least Correction Needed

Start with a conservative adjustment and recheck placement, clearance, bar contact, and stability. A large abrupt edge can create its own pressure point, so transitions should be smooth. Review our guide to saddle pads before selecting a correction system.

Recheck as the Horse Changes

A shim plan should not be forgotten. Conditioning, weight, age, and workload can alter the horse’s topline, making yesterday’s correction unnecessary or insufficient.
