I noticed right away that the Sole F85 was designed and constructed to be very sturdy. It's made in such a solid, unique way that it will last for years-if not a lifetime. The way the treadmill has been designed has allowed the company to put some really unique bells and whistles on the machine, too.

One thing that really stands out to me about the Sole F85 is its large running area. It can easily accommodate tall people and people who weigh up to 400 pounds-as well as intense runners. The machine comes with a powerful, quiet, and ultra smooth 3.5 continuous duty horsepower motor that will make all people, regardless of height or weight, feel comfortable and safe because it doesn't strain under intense pressure.

I really like the shock absorption deck on the Sole F85 treadmill. This deck will enable people to run or walk longer than they normally could outdoors. Granted, a lot of high-end exercise machines are easier on the joints and knees than the relics of the past, but the Sole F85 has a Cushion Flex deck that gives more shock absorption than other treadmills.

The Sole F85 is very stable and strong. The frame alone weighs in at 280 pounds. Yet, despite its weight, it is easy to fold due to its easy assist folding feature. I also found that the treadmill is easy to roll around and maneuver, too. This makes it ideal for people who need to move their machine after using it.

Unique features that I like on the Sole F85 treadmill include the two onboard cooling fans and the built-in speakers for iPods or MP3 players. Obviously, Sole Fitness has really put a lot of thought into the treadmill and figured out ways to make consumers more comfortable during their workouts.

If you are in the market for a treadmill, check out the Sole F85. Besides the things I mentioned, the machine has a lot of features that are sure to please such as speed and incline controls on the arm rests, a lifetime warranty on the deck, frame and motor, and a five year warranty on parts. The Sole F85 is by far one of the best deals on the market. I have no questions now as to why this machine is the best selling treadmill that Sole Fitness offers.
