When comparing the Smooth 6.45 and the Sole F80, there are more similarities to be found than differences. Each of these treadmill models are so similar that anyone who is considering one of these for purchase, will definitely have a tough decision to make.

Let's Get To The Specs

The treadmills have the relatively the same basic facilities: speeds of up to 11 miles per hour, up to 15% incline level and 3.0 HP motors with continuous duty facility.

The Sole F80 is lighter, weighing in at 250 pounds, while the Smooth 6.45 weighs 265 pounds. Despite the small weight difference, stability is guaranteed from both machines even with a 350-pound runner using them. The Smooth model though. has a larger running area offering 20 by 60 inches, while the Sole model is restricted to an area of 20 by 55 inches.

Easy To Use Controls And Programming

Both machines have LED consoles useful for displaying the user's important data which includes the time elapsed, speed, and the total distance covered. You also get the convenience of added programs that are either preset ot customized to fit your workout needs.

The Sole F80 comes with 6 standard programs and 2 heart rate programs, plus another 2 programs which can be customized by the user himself. The 6.45 is equipped with 8 challenging preset programs and 3 user-defined programs. Both machines have hand pulse grips but the F80 model comes with a wireless chest strap for easier monitoring of your heart rate.

Additional Features

Do you want to enjoy the latest hits along with your jogging? Then you have the option of enjoying both workout and entertainment as Sole has built-in speakers where you can easily plug the MP3 player or your ipod and enjoy music while doing your exercise. The Smooth 6.45 model does not have this facility but the sister model, the Smooth 6.45M, is already equipped with the speaker facility but costs a hundred dollars more.

Coming with extra points for convenience is the Sole F80. This model lets users adjust speed and incline easily with the accessible arm rest controls. This allows for changes to be made for a better workout or allow for interval training without having to stop and adjust.

Better Warranty And Price

Both of these top treadmill exercise models are higher priced than most. They range in MSRP from $1999 up to $2297. However, they can be found on sale for only $1499. The lifetime warranty on motor and frame, 5-year warranty on all electronic parts, and 2-year guarantee on labor is applicable for both treadmills, and this makes each a great investment in exercise equipment.

Sole F80 vs Smooth 6.45 - Getting the best one

Both the sole and the smooth treadmills have the capacity to keep up with your daily workout. However, if you would have me make the choice for the best, I'd go for the Smooth 6.45. Though Sole has some additional features that are absent in the 6.45, I would still prefer the larger running area of the Smooth model. Besides, Smooth 6.45 is really one of Smooth Fitness' best treadmills.
