Question about Erard Standit 600

Does anyone know what kind of anti-slip stickers are used on the underside of the foot? I suspect something from 3M but can't find anything suitable. Our stand is slowly sliding forwards over the sticker from the wall due to the weight and I would like to replace it. For whatever reason, the non-adhesive silicone side sticks better to the wooden floor than the adhesive side to the metal of the base :)
