If it is a basic pad (made of just the ThinLine foam), then the answer is yes! Use a utility knife (box cutter) or a sturdy pair of scissors. Make rounded cuts. No “V” shapes- they will tear. Keep in mind however, we do not warranty pads that have been modified if they tear at a point caused by cutting.
My ThinLine pad is a little too big for my saddle, can I cut it down?
