The Sole F85 and the Sole TT8 are two high-quality treadmills from Sole that share many similarities but also have some distinct differences. Both models are powered by a 4 HP motor and offer a speed range of 0.5 to 12 MPH. They both have a weight limit of 400 lbs, come with 10 built-in programs and custom profiles, and include a tablet/device holder, cooling fan, audio, and Bluetooth audio. Their belt sizes are also identical at 22″ X 60″. Both treadmills also include handlebar buttons and are equipped with pulse grips for heart rate monitoring.
One key difference is that the F85 model is foldable, while the TT8 model is not, making the F85 a better option for those with space constraints. The TT8 model offers an incline/decline feature with 15 levels of incline and 6 levels of decline, while the F85 model only offers 15 levels of incline. The TT8 model comes with a 10.1″ TFT touch panel and an Android system, whereas the F85 model has a 10.1″ TFT LCD display but does not have a touchscreen. Another difference is that the TT8 model is compatible with the STUDIO training app (membership required), while the F85 model does not offer this feature. The TT8 model also has larger rollers at 3″, compared to the F85 model’s 2.75″ rollers.
When it comes to warranty, both models offer a lifetime warranty on the frame and motor. However, the TT8 model offers a longer warranty on electronics (5 years) and labor (2 years) compared to the F85 model’s 3-year warranty on deck, electronics, parts, and 1-year warranty on labor.
Here is a list of the most important differences:
- Folding: The F85 model can be folded, while the TT8 cannot.
- Incline/Decline: The TT8 model offers 15 levels of incline and 6 levels of decline, while the F85 model only has 15 levels of incline.

- Rollers: The TT8 model has larger rollers at 3″, compared to the F85 model’s 2.75″ rollers.
