Sole TT8 Treadmill Review (Updated 2020)

For some people, running on a treadmill can require a lot of motivation. Even if they’re some of the best reviewed treadmills, they might prefer running outdoors for the free rein of elevation and space. Some might feel that treadmills are too noisy to have in their homes. Thankfully, the Sole TT8 is a powerful but quiet treadmill that features a wide running surface and both incline and decline settings.

If you’re looking for a strong treadmill that can help you shake up your runs, our review of the Sole TT8 might convince you that it’s the right one for you.  

Main Takeaway 

  • This treadmill can be set at an incline of up to 15% and declines of -2% and -4%.
  • It exceeds some standard treadmill motor, roller, and running area sizes with a 4.0 horsepower motor, 3 inch crowned rollers, and a belt that is 22 inches wide.
  • The Sole TT8 is Bluetooth compatible and provides buyers a variety of options on how to utilize their smart devices throughout their runs.

Sole TT8 Treadmill Highlights

The Sole TT8 is built to be durable enough for both home gyms and light commercial use. Its powerful motor and all-steel construction allow this treadmill to sustain up to 400 pounds and hit a max running speed of 12 miles per hour. Its larger than most 3” rollers will help with the belt’s longevity and to create a smooth and quiet running surface for runners. While its 10 included workouts are classic programs long time runners should be familiar with, both its decline settings and Bluetooth compatibility give the TT8 some modern upgrades.

With a 22 inched belt, runners get a much wider running surface on the Sole TT8. Other standard treadmills have widths of 20” or even 18”.

Who Should Buy the Sole Fitness TT8

  • People who want to add uphill and downhill training into their runs.
  • Big and tall runners as this treadmill has a higher weight capacity and a much more spacious running area.
  • Folks who have the space to fit the TT8 in their home gym.

Who Shouldn’t Buy the Sole Fitness TT8

  • Buyers on a tight budget as the TT8 is the most expensive treadmill in Sole’s collection. 
  • Runners who want more variety in the treadmill’s pre-installed workouts like interactive workouts.
  • Anyone who wants a foldable treadmill as the TT8 does not fold.


The TT8 is priced at $2,499.99 on the Sole Fitness website. While it is one of Sole’s more expensive treadmills, it is one of the few that has a 4.0 hp motor and a 22” running belt. It is also the only Sole treadmill that can be set at two different decline gradients. 

Overall Build and Quality

The Sole TT8 is built to be sturdy and long-lasting. Its frame is constructed with high-grade steel which will help prevent the treadmill from rusting. Its structure is also hand-welded and then coated with an epoxy powder to produce a truly solid piece of fitness equipment.  


The Sole TT8 has both standard and some more contemporary features that should appeal to many users. The easy to navigate console is big and bright and can benefit those just starting to run, while its Bluetooth compatibility offers users some modern conveniences.

Incline range  

Users wanting to imitate their outdoor runs can do so with the TT8. Not only do they have control over their incline levels, but they also have the option to put their treadmill in modes of decline. With the quick select buttons on the console or the adjustment arrows on the handrails, runners can add elevation to their runs by increasing their incline levels up to 15% and decrease their declines by -2% or -4%. Gradients can be adjusted in 0.10 increments.

Speed range

Just like many other Sole treadmills, the TT8 can hit high-speed levels. It’s 4.0 hp motor gives users the ability to run from 0.5 mph up to 12 mph. This speed is slightly higher than other treadmills on the market which can only go as fast as 10mph. 

Included workouts

The Sole TT8 comes with 10 pre-installed workouts. Seven of these are programs avid runners might be used to like an interval option, a cardio setting, and a training to increase lower body strength. This treadmill also has two programs that allow runners to work on their heart rate goals. 

One setting that might be new to some runners is the Fit Test. This program determines just how fit a runner is by estimating how much oxygen they consume during their workout. Runners are challenged throughout 11 minutes of increased speed and incline in an attempt to reach different stages of maximum oxygen levels. By gripping the pulse sensors on the TT8,  the user can track their heart rate and the Fit Test will use the data to assess just how much oxygen the runner is using. This kind of program can benefit users who want to evaluate their cardio and improve their overall fitness level.  


The Sole TT8 offers a user-friendly display that is easy to read. Its vibrant 10.1 inch LCD screen allows runners clear readings of their metrics such as heart rate, speed, pace, calories burned, and pulse. Since the TT8 is Bluetooth compatible, users also have the option to use either the Sole Fitness or Garmin app to display their dashboard.  


The Sole TT8 comes equipped with one cooling fan. This fan is compact, adjustable, and strong enough to give runners a nice breeze. 

Heart Rate Monitoring 

This treadmill makes it convenient for users to track their heart rate. Runners can grip the pulse handles and the TT8 will read their heart rate. Those interested in a heart rate monitor can check out this list of fitness trackers for more options.

Runners can use the two included heart rate workouts to give themselves more of a challenge. Training one will keep the runner at a 60% maximum heart rate while the second setting will start their runners at 80%. 

HDMI, USB, and Other Inputs 

Sole Fitness upgraded the TT8 from its previous model to have a USB port. Earlier versions of this treadmill have an aux cord so that runners can connect their smart devices. 

Bluetooth and Audio Options

Using Bluetooth, runners can listen to music playing on their smartphones and tablets through the console’s two speakers. Users can also transfer and save their data to and from the treadmill. 

Water Bottle, Cup Holders, Tablet and Phone Holders

This treadmill offers tons of storage space. There are two water bottle holders on either side of the console which can be great for anyone who likes to stay hydrated by drinking both water and electrolytes. The holders also have a divided pocket so you can place your keys or phone near your water bottle. This will serve anyone who likes to keep all their belongings in one spot. 

If you’re the type of person that likes to have nothing in your way while you run, then the accessory tray below the console might work better for you. It also has a water bottle holder and two other sections for your wallet or a small gym bag. 

Product Specs

The Sole TT8 is built to be a heavy-duty treadmill that’s going to serve its users whether they’re performing a light jog or sprinting. It’s also a piece of equipment that provides many different runners plenty of cushioning and comfort.

Motor Size 

The TT8 is one of the few treadmills in Sole’s collection to include a 4.0 hp motor. This motor helps the TT8 reach higher speeds and various incline levels. Users can still enjoy a smooth and vibration-free running surface since Sole Fitness added a commercial-grade flywheel to its powerful motor to keep it running smooth and cool.

Running Area  

Users will enjoy this treadmill’s spacious running area. Its belt measures in at 22”x 60”, which is a few inches more in both width and length than some other standard treadmills. This belt can give runners much more room to incorporate some other movements while they run, like side shuffles or karaokes.

Weight Capacity

Its powerful motor and all-steel construction allow this treadmill to sustain a lot of weight. The Sole TT8 can support up to 400 pounds, one of the highest weight capacities in the Sole treadmill line.

Folding Options  

The Sole TT8 is not foldable. Shoppers interested in a foldable treadmill with the same sized motor and running area might be interested in the Sole F85.

This treadmill has a footprint of 82”x36”x58”. It’s a good idea to have a designated area for this treadmill since it’s not foldable and will take up some space in your gym.

Electrical Requirements 

Even with such a strong motor, buyers of the TT8 can plug their treadmill into their wall outlets at home. This treadmill requires a 110 volt/15 amp outlet which is pretty standard for most homes. 


Sole Fitness offers both residential and light commercial warranties on the TT8. If you’re buying the TT8 for your home gym, Sole Fitness provides lifetime warranties on its frame, motor, and deck. It also guarantees coverage of the treadmill’s electronics for five years and labor for two years.

Sole Fitness also offers a lifetime warranty for light commercial use of the TT8 but the motor and deck warranties are only good for five years. Its electronics are covered for three years and labor is guaranteed for one year.

Belt Information and Roller Size  

While some treadmills only use 1-ply belts, Sole Fitness constructs the TT8 with double woven 2-ply belts with four layers. Its two rubber layers help the belt stay tough and resistant to wear and tear, while the thermoplastic sheet prevents the belt from overstretching. These three layers are accompanied by a nylon backing that makes contact with the deck and rollers smooth and static-free. 

This deck is also reversible. Runners can flip the tread over to prevent it from wearing down excessively on one side. This can add longevity to the belt’s life.

The TT8 comes equipped with 3″ crowned rollers. It’s worth mentioning that these rollers are larger than some of the other treadmills in the Sole line. Bigger rollers mean the belt has more contact surface to glide over. This can also extend the life of the belt.  

Cushioning and Feel 

With four layers that make up its 2-ply belt, the TT8 has ample amounts of cushioning. This surface can reduce impact up to 40% and with a good pair of training shoes, can make running on the TT8 much easier on the joints. Along with the rollers and flywheels, the belt is also designed with a CushionFlex Whisper Deck which produces a quiet surface for users to run on no matter how hard they’re working. 

Workout Apps and Compatibility 

The Sole TT8 is compatible with a variety of workout apps. Buyers can download the free Sole Fitness app for basic data tracking and it includes a feature where runners can display the treadmill’s dashboard on the screens of their smart devices. This treadmill is compatible with some fitness trackers and can be used with their apps such as Garmin Connect. Runners can also use UA Record, Map My Fitness, Fitbit, iHealth, and My Fitness Pal to track their metrics.

Subscription Options

Users of the TT8 are going to have to get their running videos from their smart devices. While Sole Fitness does not provide a subscription for video workouts or downloadable content, runners can still stream their favorite routines off their phones and tablets. Thankfully you’ll have plenty of space to place your handheld device in front of you. 

Places to Buy 

The TT8 is available to purchase from the Sole Fitness website. Older models of this treadmill can be bought off of Amazon from other sellers.

Final Word 

With such a strong frame and motor, the TT8 can be used by many different runners. The ability to add decline levels is a nice bonus for those who prefer running outdoors, while its Bluetooth compatibility might attract those who like to use their handheld devices while they run. While it sticks to some classic features, the upgrades on the Sole TT8 make it a viable option for those who like the latest technology in their fitness equipment. 


Is the Sole TT8 an expensive treadmill?

This treadmill is on the higher end when it comes to price range since standard treadmills usually cost between $1,000 to $2,000. You will spend a little more on the TT8, but that takes into account its construction and its features. You can purchase a cheaper treadmill but it probably won’t have such a powerful motor, 2-ply belt, 3” crowned rollers, or the option for decline levels.

Is the Sole TT8 easy to move?

It’s recommended to have committed space for this treadmill as it is not foldable and weighs 322 lb. It does have wheels under the frame that might make it a little easier to move, but shoppers interested in a lighter and foldable treadmill can read our F65 review to see if it’s a better fit for them.

What is the difference between the Sole TT8 and the Sole F85?

Both treadmills have motors of 4.0 hp and a running surface of 22”x60,” but the differences lie in the decline and folding options. The F85 does not offer a decline setting but is foldable, while the TT8 can be put into decline modes but does not have the option to be folded.
