RE: footpads getting loose
Contact cement is the classic product for the job. However, before applying any fresh cement, you need to remove any old contact adhesive from both surfaces. Also, it's a good idea to sand both the board and the pads to ensure good adhesion. If you find any non-slip texture on the board in the area under the pad, it's wise to remove it. Finally, you apply the contact cement to both the board and pad and let both dry before placing the pad in place.
