The Thin ImpacTeq® Felt Shim Set is an essential tool for precision saddle fitting, designed exclusively for use with EquiFit’s Thin ImpacTeq® Half Pads with Shims. Whether adjusting for asymmetry, supporting horses in training, or maintaining balance across multiple horses, this complete set offers a customizable solution without adding bulk. Each set includes six 6mm felt shims—shoulder, center, and rear—to provide targeted lift and pressure relief exactly where it’s needed. Pony sets include four shims (shoulder and rear) for appropriately scaled support. Crafted from durable, high-quality felt, these shims retain their shape, encourage airflow, and deliver consistent, breathable support under the saddle. Seamlessly contoured for a secure, non-slip fit inside the shim pockets, they integrate cleanly to protect the horse’s back while optimizing saddle contact and performance ride after ride.
