ThinLine English Trim To Fit Shims

ThinLine English Trim-to-Fit Saddle Fitting Shims are a durable, foam-based solution designed to fine-tune saddle fit while protecting your horse’s back and boosting comfort for both horse and rider.

• Thickness: 3/16" (4.8mm) thin to add subtle height without bulk.
• Material: Shock-absorbing comfort foam used in ThinLine saddle pads for consistent cushioning.
• Durability: No expiration date; foam never compresses or deteriorates, so shims last a lifetime.
• Pack and guidance: Supplied in pairs with scoring marks and trimming guidelines to help you create front, bridging, or rear shims.
• Trim-to-fit versatility: Trim with scissors or a box cutter; surplus pieces can be stacked to adjust height; full shim option provides economical, all-in-one fit.
• Fit accuracy: Inserts stay in place without shifting; pocket is not divided, allowing precise placement exactly where your horse needs it.
• Bridging Shims for swayback: If your saddle is bridging, start with 1–2 shims; can balance contact and encourage top-line development, potentially reducing the need for future shims as muscles build.

Benefits: By adding targeted height and support, these shims help eliminate pressure points, improve saddle contact along the horse’s back, and increase rider comfort. They stay securely in place, are re-trimmable and re-stackable as your horse grows, and the full-shim option offers a cost-effective way to protect the saddle pad and back. For swaybacks, bridging shims can help even out contact and support muscle development along the top line, with the possibility of removing some shims over time as the horse strengthens.
