These pads may not seem like an important equipment addition but they do significant aid reduction in vibration caused by wind and other factors. The pads consist of a hard outer shell and an inner disc on which the foot of the tripod sits on. Between the two is (what appears to be) a gel-filled area that effectively absorbs minor vibration. I primarily use my scope for astrophotography and therefore vibration reduction is important. Im pleased to say this product does it job very well and has aided me in obtaining some images.
