Sole TT8 Review 2021

          Our Rating: 4.8/5


When it comes to top of the line treadmills, the Sole TT8 is the cream of the crop. The most expensive treadmill that Sole has to offer, the TT8 takes all of the features that make the F85 so great and add a second motor, enabling users of this treadmill to walk, jog or run while the treadmill is in either an incline, decline or neutral position.

If simulating outdoor running is a must have in a treadmill, look no further than the TT8. The below review gets into the specifics on Sole’s top-end treadmill.


Build Quality

The Sole Fitness brand has built a reputation of utilizing industrial strength parts to build their commercial-grade treadmills often favored by hotels due to durability throughout heavy usage.

The most dynamic and revolutionary of their treadmills is the top of the line TT8 model, which is the only Sole model with strength verified for light-commercial use of up to five-hours of daily function, making it ideal for fire or police stations, as well as living complex gyms.

Touted as being deliberately created for serious athletes, the TT8’s motor comes packed with ultimate power. Commanding an energetic 4.0 HP of main motor force, the TT8 treadmill is the only model that comes with not one, but two substantial high-torque motors as the addition operates the decline feature. While people often think of incline as a thorough work-out, they fail to consider how decline works to target additional muscles within the body, which is why outdoor work-outs are favored by dedicated fitness buffs interested in well-rounded training.

Having a decline feature provides admission to all the benefits of an outdoor workout within the comfort of your own home, on your own time. Partnering with the motors are large balanced zinc-coated flywheels which further increase their life.

The bullet-proof all steel frame has been welded with the most precise technology, allowing it to handle a variety of workouts and body types up to 400 pounds. To prevent stretching through time, the 2-ply belt is created using two rubber layers, a middle layer of PVC and a nylon backing.

Sole does not skimp on roller quality to boost profit like a lot of other brands do; instead, they opt for high-end giant rollers as the size of rollers matter. The larger roller expands surface contact with the belt, extending longevity of both the belt and roller. You will notice this difference in real-time by way of smoother, quieter and static-free treadmill performance.

Further setting the Sole TT8 treadmill apart from other brands is the impactful whisper quiet cushion deck, effectively diminishing joint strain, ultimately increasing the recovery process to prevent additional rest days between workouts. Not only does this deck make your body feel good, it also further reduces operating sound and motor strain through its wax lubrication. The TT8 treadmill truly is top of the line when it comes to quality consideration.



If you’re looking for functional and accessible technology to further enhance the endorphins you receive from exercise, the TT8 will meet your needs.

The considerably sized 10.1” TFT LCD display provides clear communication of how your work-out is going. With pace, incline, decline, time, distance and heart rate, you will always be in the know of your progress.

Heart rate is measured via Salutron pulse grips or an additional-cost chest-strap, making the choice one for you to make as to which you prefer. The Sole heart rate readout is proven to be 99.9% accurate.

The vibrantly clear display also reveals a peak and valley graph to more easily track your incline and decline as well as granting a visual to the six standard, one customizable and two heart-rate workouts offered.

Pump up the jam, pump it up while your feet are stompin’ and the jam is pumpin’ using the bluetooth speakers, which easily pair to your smart device. Bluetooth technology also allows you to transfer your work-out summaries for easy tracking on your smart device.

Not only will this quality treadmill not die on you, neither will your phone or tablet as the USB port charges your devices conveniently so you can keep them in easy reach. Speaking of easy reach, the tablet holder thoughtfully contributes a space to store a Kindle, phone or tablet for easy viewing ability.

We appreciate the perfectly placed controls such as the start and stop button and all function options as touch-screen technology on more expensive commercial grade treadmills often results in frustration to operate due to over sensitivity or lack thereof, especially if you’re sweaty.

With the TT8, you’ll never have to worry about spending time on product updates or bug-fixes. The Sole TT8 treadmill provides easily operable technology to deliver an outshining workout experience.


Price Point

Rated best commercial price for 2020, the Sole TT8 treadmill brings its A-game when it comes to credible reliability and high-end parts at a considerably lower price compared to its competition. While the most expensive Sole model, the TT8 is still far cheaper than other light-commercial grade incline/decline treadmills on the market today.

The incredible 4.0 motor provided certainly makes the TT8 the best bang for your buck when it comes to power as the Nordic Track Commercial X11i only offers 3.75 HP while priced the same and with far smaller warranty coverage than the TT8 offers. While the Nordic track appears more advanced, it doesn’t match up to the TT8 in long-term functionality and assurance.

We are thankful for the option Sole has provided us in a trusted, reasonably-priced and straight forward option for a light-commercial incline/decline treadmill in the TT8.


Pros and Cons

The highest end model and only Sole choice for an incline/decline treadmill, other Sole treadmills, such as the F80 and S77, aren’t easy to compare to the TT8 as they lack its main purpose: to emulate outdoor exercise with the additional decline motor and function.

The access to an outdoor workout at any time of the day or night without weather concerns that you can personalize to work with your busy schedule makes the contribution of the TT8 to your routine a truly priceless one. However, if you are focused on more advanced technology such as a touch screen rather than stronger motor power, while still smaller in display size than the TT8’s, the Nordic Track X11i might be a better match for you.

However, it’s important to note that the X11i comes with a much smaller warranty for personal use than the TT8 offers. The burning 15 levels of incline and six levels of decline verifies just how fierce your exercise will be with the TT8 treadmill. When paired with the amazing incline/decline option, the 4.0 continuous horsepower motor providing speeds up to 12 mph reserves the TT8 for those serious about growing their wellness strength.

As noted in the build section, the high end and larger parts used result in the TT8 offering smoother transitions when altering decline and incline levels mid-workout as well as quieter function despite the intense power. Reviewing the Sole TT8 treadmill reveals its ability to out-power its competition in longevity, durability and power, but not advanced technology such as a touch display screen and substantially more pre-loaded work-out programs.

Warranty and Guarantee

If you’re intending the Sole TT8 treadmill to be for personal use, the warranty offered is unmatched to competitors. Lifetime warranty is awarded to the highest grade steel frame, cushion flex whisper deck as well as the high-torque motors.

In comparison, the Nordic Trac X11i only offers a limited 10-year frame warranty and no motor or frame protection. Coverage of 5-years extends to the Sole TT8’s electronics while the Nordic Trac X11i limited warranty covers no electronics. Meanwhile, the Sole TT8 offers 2-years of warranty protection for labor while Nordic Trac provides half that amount for the X11i.

Interesting to note is that there is no warranty listed for the Sole TT8 when it comes to parts, despite there being 2-years of part coverage on less expensive Sole treadmill models. This could be an oversight, but an important one to draw an inquiry into. That being said, Nordic Trac X11i offers a 2-year warranty on parts.

Sole specifies a different warranty should the TT8 treadmill be purchased for light commercial use. If commercial use is intended, there is a Lifetime warranty on the frame while the motor and deck drop down to a 5-year warranty. Also decreased in time are electronics and labor, which are covered for 3-years and 1-year, respectively.


Summing Up This Review

If you are looking to invest your fitness with a trustworthy Sole product, the TT8 far surpasses other treadmill models with the added decline function and stamp of light-commercial use approval which speaks to its great strength.

The Sole TT8 treadmill is ideal for those who are serious about their fitness routine targeting more muscle groups through the decline ability, ultimately mimicking a workout given by the great outdoors.
