From D’addario:

“DAddario XPND Pedal Risers are designed to elevate pedals in those tough to stomp places. Mount the risers using the included hook and loop strips and raise any pedal a full inch, making it easy to access. You can align multiple risers across your board as needed, and with built-in-cut-outs for simple cable routing, adding risers is quick and hassle-free. XPND Pedal Risers are built to last and are available in single or double width, to accommodate dual-sized or multiple pedals.”
