Short answer
Choose Sole if you want a running treadmill with lifetime frame and motor coverage, up to 15% incline and no required membership; the TT8 and F89 add 6% decline. Choose NordicTrack if you want iFIT classes on a touchscreen that adjusts speed and incline for you, from the T Series 16 to the Commercial 2450.
Key takeaways
- Sole is the better pick for running-first buyers who want long warranties and no membership.
- NordicTrack is the better pick for iFIT classes, touchscreens and automatic workout control.
- Sole offers more incline (15%) and more decline (6% on F89 and TT8) than NordicTrack (12% and -3%).
- Every Sole we reviewed lists lifetime frame and motor coverage; NordicTrack terms vary by listing.
- The Sole TT8 (93.8) and NordicTrack T Series 16 (92.4) are the top-rated models of each brand.
Sole vs NordicTrack is the classic choice between a running-first brand and a classes-first brand. Sole builds heavy, simple treadmills with long warranties and leaves the software to free or third-party apps. NordicTrack builds its range around iFIT, with touchscreens, trainer-led workouts and automatic speed and incline changes. Both make treadmills that suit serious runners, but they get there in different ways.
This comparison uses the 5 Sole and 9 NordicTrack treadmills we reviewed at FitGearHQ. We compare lineups, motors, decks, incline and decline, consoles, subscriptions and warranty patterns, then pick the best model from each brand by need. For every other brand, see our best treadmill brands guide.
Sole vs NordicTrack at a Glance
On paper the two brands overlap at the top: both offer 22 × 60-inch decks, 4 HP-class motors and 400 lb capacities. The differences show up in warranty length, incline range, how the console works and whether you pay a membership. The table compares the models we reviewed.
FitScores come from our reviews. Each Best guide re-weights the same treadmill for its use case, so the score in a guide can differ from the review score.

Lineup Differences
Sole keeps a short, running-focused range. The Sole F50 (FitScore 74.6) is the entry point with a 2 HP motor and 20 × 55-inch deck. From there, every model uses a 22 × 60-inch deck: the F65 (80.9), F80 (82.7), F89 (90.1) and the non-folding TT8 (93.8), the highest-rated treadmill we have reviewed.
NordicTrack has a deeper range with two families. The T Series covers walking and jogging, from the T Series 5 (72.9) and T Series 7 (80.4) to the touchscreen T Series 10 (82.4) and T Series 16 (92.4). The Commercial family targets runners: the Commercial LE (83.3), 1250 (83), 1750 (85.4) and 2450 (86.7).
The practical takeaway: Sole has fewer walking-only models, and almost everything it sells is sized for running. NordicTrack has more choice at the walking end, where the T Series 7 ranks #1 in our best treadmill for walking guide, and a strong running tier in the Commercial line.
Motors and Decks
Motor power is close at the top. The Sole F89 and TT8 use 4.0 HP motors, while the NordicTrack Commercial 1750 and 2450 use 4.25 HP. The Sole F80 (3.5 HP) and F65 (3.0 HP) line up against the NordicTrack T Series 16, Commercial LE and Commercial 1250 (3.6 HP each). The NordicTrack Commercial 2450 is the only model in either brand that reaches 14 mph; all Sole models top out at 12 mph or lower.
Deck size favors Sole across more of the range. Four of the five Sole models we reviewed use 22 × 60-inch decks, including the mid-range F65. NordicTrack reserves 22-inch-wide decks for its Commercial models; the T Series 10 and 16 use 20 × 60 inches and the T Series 7 and 6.5 S use about 20 × 55 inches.
Cushioning feels different. Sole uses its Cushion Flex decks, which testers describe as supportive rather than soft. NordicTrack offers SelectFlex on the T Series 7, 10 and 16, adjustable from soft to firm, which helps explain why the T Series 16 ranks #1 in our best treadmill for bad knees and best treadmill with cushioning guides.
Incline and Decline
Sole offers more incline. The F65, F80, F89 and TT8 all reach 15%, and the F50 reaches 12%. NordicTrack models we reviewed top out at 12% (10% on the T Series 5, 7 and 6.5 S). For steep incline walking, Sole gives you more range on every model above its entry point.
Both brands offer decline on their premium models, but in different amounts. The Sole F89 and TT8 go to 6% decline. The NordicTrack Commercial LE, 1250, 1750 and 2450 go to -3%. Sole has the bigger total range, while NordicTrack can change incline and decline automatically during iFIT workouts.
That automation is a real difference. With an iFIT membership, NordicTrack changes speed and incline to follow a trainer or route. Sole says its treadmills support Bluetooth FTMS, which lets apps such as Zwift and Kinomap control speed and incline on supported models. You get automatic control with either brand, but through different software. See our best treadmill with incline guide, where the Sole F89 ranks #1.
Pro tip: If you train for hilly races, the Sole F89 and TT8 cover 21 percentage points of grade (6% decline to 15% incline), the widest range of any model we reviewed from either brand.
Consoles, Apps and Subscriptions
NordicTrack is built around a screen. The T Series 10 and Commercial 1250 use 10-inch touchscreens, the T Series 16 and Commercial 1750 use 16 inches, and the Commercial 2450 uses a 24-inch tilt-and-pivot screen. The lower T Series models and the Commercial LE use small LCDs and stream iFIT to your own device. According to iFIT, the Train tier covers phones and tablets, while the Pro tier covers built-in screens; NordicTrack says only Pro allows extra household users and that the treadmill still works in manual mode without a membership.
Sole takes the opposite approach. The F80 has a 10.1-inch touchscreen, the TT8 a 15.6-inch touchscreen and the F89 a 21.5-inch touchscreen, while the F50 and F65 use LED and LCD consoles with built-in programs. Sole says the SOLE+ app is free with no trial countdown or premium tier, and its treadmills connect to third-party apps over Bluetooth. You can add a paid app if you want classes, but nothing is required.
The choice is simple. If trainer-led classes and automatic adjustments keep you motivated, NordicTrack delivers the most complete experience and the 2450 has the largest screen in this matchup. If you prefer your own plan or already pay for an app, Sole avoids a second recurring cost. Our best treadmill without subscription guide ranks the Sole F65 among its top picks.
Watch out: A NordicTrack touchscreen without an iFIT Pro membership loses classes, streaming and automatic control. Factor in the membership for as long as you plan to use the treadmill.
Warranty, Build and Support
Warranty is Sole’s biggest advantage. Every Sole model we reviewed lists lifetime frame and motor coverage. Parts coverage runs from 1 year (F50, F65, F80) to 3 years (F89, TT8), and labor from 90 days (F65, F80) to 1 year (F50, F89, TT8). The weak spot is labor on the mid-range models, so factor in local service if you run hard.
NordicTrack is less uniform. T Series 5, 7, 6.5 S and 10 listings show a 10-year frame with 1 to 2 years on motor and parts. The T Series 16, Commercial LE, 1250 and 1750 listings show 2 years on frame, motor, parts and labor. The Commercial 2450 listing is the exception, with a 10-year frame, lifetime motor, 2-year parts and 1-year labor. Check the current warranty on the product page, since terms can differ by seller.
On build, the Sole TT8 is non-folding with a 400 lb capacity, and the F89 folds but weighs about 314 lb. NordicTrack Commercial models fold and carry 400 lb ratings. Both brands are heavy at the top of the range and usually ship by freight, so plan help for setup.

| Sole F89 | Lifetime | Lifetime | 3 years | 1 year |

Frequently Asked Questions
Sole is better for runners who want lifetime frame and motor coverage, up to 15% incline and no required membership. NordicTrack is better if you want iFIT classes on a large touchscreen with automatic speed and incline control.
We cannot measure lifespan directly, but Sole lists lifetime frame and motor coverage on every model we reviewed, while most NordicTrack listings show 2 to 10 years on the frame and 1 to 2 years on the motor. Longer coverage is a good signal of expected durability.
No. Sole says the SOLE+ app is free with no premium tier, and its treadmills connect to third-party apps over Bluetooth. You only pay for an app if you choose one.
Yes. According to NordicTrack, the treadmill works in manual mode with a small set of onboard workouts. Classes and automatic adjustments need an iFIT membership.
Both, on premium models. The Sole F89 and TT8 go to 6% decline, and the NordicTrack Commercial LE, 1250, 1750 and 2450 go to -3%.
The Sole F89 is the closest match: a folding treadmill with a 4 HP motor, 22 × 60-inch deck, decline and a 21.5-inch touchscreen. The 2450 is faster at 14 mph and runs iFIT; the F89 has more incline and a lifetime motor and frame.
