The Classic Equine BioFit Shim Felt Saddle Pad features a thick orthopedic fleece center that absorbs shock and disperses pressure. It has a premium grade felt bottom with a shock-absorbing wool felt center. The closed-cell foam shim is wedge-shaped to alleviate saddle fit issues and is contoured to fit the horse’s shape more closely. This pad also alleviates “downhill” saddle fit due to atrophy or conformation issues at the withers. Additionally, it offers adjustable correction; simply slide the shim forward for less lift or back for more support.
