Hi Marcie, there are only a couple of feet of exposed hose on both ends. The sock relaxes after installation and stays in a comfortable, effective place on the hose. The entire center of the hose is covered, protecting it and your home as it is slithered around from room to room. The ends of the hose are not the culprits for wear and tear. If you want to get the longer cover for the 30ft hose that would be fine. If it is too long just twist the sock a couple of times and it will shrink down.
