I've had them come off pretty easily unintentionally. All it took was a a little heat and I've accidentally pulled them off while manhandling my board. But it probably depends on the stomp pad and board.
And I second the Dakine Pyramid Studs. They look less like a stomp pad, and at least for my old snowboard (which looked kind of like this), went well with the rocker look and made it look better. Plus, one set of these is good for two boards.
While you don't absolutely need a stomppad, and I've been too lazy to put them on my new boards, I like the security of having one.
I rock em. Im not ashamed. Dont mind the look and for longer downhill skates I like that I have it there. Just coming off the lift both feet are near the front binding anyway. Defeats the setback rocker on the Raptor and uses the camber section to skate straight.
