I removed the grip and had no problem due to cold temperature
(This seems to indicate that the glue of the grip could be responsible).
Then, I put on the footpad the foam "Traction Pad" from ProRide.
For this, I left the board and the pad outside in the cold for a moment, before sticking the pad.
Since then, I did not have any "ghost rider" problem.
To conclude, I had problems with classic skate grip tape from Vicious and Black Diamond, and now that I have ProRide pads everything is fine.
