The main differences between the SOLE F85 Vs. the TT8 are: The TT8 is a heavier duty commercial model (non-folding), and has a -6% decline grade which simulates downhill running and builds up different muscles. Both models have a 15% powered incline grade. Both treadmills have a heavy duty motor (4.0 Horsepower), higher Maximum User weight (400 lbs.) and are designed for heavy duty usage. The TT8 has larger rollers (3-inch vs. 2.5-inch). Both models come with an excellent warranty (better than most treadmills). The Sole Treadmills also have high consumer ratings. Below is a comparison chart of the differences between the two treadmill models.

Sole F85 Control Console with 10-inch Color HD Touchscreen. 18 workout programs. Tablet holder with USB charging port. Wifi Enabled.

The SOLE TT8 Treadmill has a 10.1-inch monochrome LCD screen, and 10 built-in workout programs. Pulse & Telemetry Heart monitoring. Tablet holder and a USB charging.
SOLE F85 Vs. TT8 Console Comparison: The Sole F85 has a newer type of touchscreen console, while the TT8 maintains the traditional type of console. The F85 provides 18 built in programs, while the TT8 has 10 built-in programs. Both have speakers, heart monitoring, and workout fan. The TT8 has an extra setting for decline grade. Both consoles are Bluetooth® enabled to connect to wireless heart telemetry and Bluetooth audio speakers . For safety, both have an emergency stop button, and cord.
Bottom Line: The TT8 offers a stronger heavier fixed frame, larger 3-inch rollers, as well as 6 levels of decline (not on the F85). Two motors control the incline/decline on the TT8. Decline simulates running downhill and builds up different muscles. Both treadmills have a running belt that is 22-inches (wider than most treadmills). The TT8 is a light commercial model, built to last longer and is heavier duty than the residential F85.
The F85 has the newer 10-inch touchscreen with APPs, and has more workout programs, tablet holder. Both models have the same excellent warranty which surpasses most competitor treadmill warranties. The F85 is Sole’s best folding treadmill. The TT8 is non-folding. We believe the F85 offers more bang for the buck, and is cheaper than the TT8. However if you want negative decline, the TT8 is the only option.
The Sole models have higher consumer ratings and higher max user weight rating than most treadmills. Both models have a Tablet holder& USB charging port. Either treadmill will provide a solid workout for all users, including taller users (wide and long running belt), and is great for runners.
Sole F85 has 18 workout programs: 6 standard, 12 custom; includes Military Fitness Tests, Heart pulse grips & Heart Telemetric Strap included.
Sole TT8 has 10 workout programs: 6 standard, 1 custom, 2 heart; Heart pulse grips & Heart Telemetric Strap optional.
Treadmill Warranty F80 & TT8: Frame, motor, and deck: Lifetime; Electronics/Parts: Five years; Labor: Two years
