I have not seen anyone recommend this, but think I saw this in at least one YouTube video (but they did not call it out). I had some reservations about the ladder's surface finish not being "grippy", especially if attempting to climb them with wet shoes or when the ladder is wet. I ordered some skateboard deck grip tape, cut them into specific width and lengths to wrap around the steps. I am pleased to report that these offer tremendous grip. I am sure that they will be a pain to wash as any sponge will grab onto the tape. Other than that, it is a simple fix that will definitely make it that much safer when climbing the ladder.
