Just the foot pads...
Pull off - mark where U want them to go back down - use a contact adhesive - aerosol can of Selley's Kwik Grip or similar. Suggest aerosol as get v.even thickeness and spread w/o too much effort. Keep layer v.thin on both surfaces. Put time into cleaning surfaces and covering board where U do not want to spray.
To top it off - finish edges with clear marine silicon adhesive filler/sealer - or w/proof silicone use around shower/loos/sinks - to stop the pads peeling away so easily.
Cheers
