ProForm vs Sole Treadmill at a Glance
The two brands answer different questions. ProForm builds lighter treadmills around iFIT classes, from compact walkers to the Pro 9000 with its 16-inch touchscreen. Sole builds heavier, running-first treadmills with long warranties and no required app. The table compares the models in our catalog.
Ratings in the cards below come from our Best guides, which weight the same treadmill differently for each use case.

Lineup Differences
ProForm splits into two families. The Carbon line covers walking and easy jogging: the Carbon TL and Carbon TLS use 2.6 HP motors on 18 × 55-inch belts, and the Carbon TLX steps up to a 3 HP motor and a 20 × 60-inch belt. The Pro line adds touchscreens: the Pro 2000 with 10 inches and the Pro 9000 with 16 inches and a 3.6 HP motor.
Sole keeps almost everything sized for running. The F50 is the entry point with a 2 HP motor and a 20 × 55-inch deck. From the F63 up, every model has a 60-inch deck and 15% incline: the F65 and F80 at 20 inches wide, the F83, F85 and F89 at 22 inches, and the non-folding TT8 at the top.
In practice, the ProForm Carbon models face the Sole F50 and F63 on price and size, and the Pro 9000 faces the Sole F80 and F85 as a touchscreen treadmill. Nothing at ProForm matches the 22-inch decks and 6% decline of the Sole F89 and TT8. For a model-to-model duel, see ProForm Carbon TLX vs Sole F63.
Motors, Decks and Capacity
Sole leads on power at the top. The F89 and TT8 use 4 HP motors and the F83 and F85 3.5 HP, while ProForm tops out at 3.6 HP on the Pro 9000. At the entry level, ProForm is stronger: the Carbon TL has 2.6 HP against 2 HP on the Sole F50.
Deck width is the clearest split. Sole offers 22 × 60-inch running surfaces on four models; no ProForm in our catalog goes wider than 20 inches, and the Carbon TL and TLS are 18 inches wide. If you run with a wide gait, or simply want more room on the belt, Sole is the brand to look at.
Capacity follows the frame. Sole ratings run from 300 lb on the F50 to 400 lb on the TT8, which weighs 296 lb. ProForm ratings run from 300 to 350 lb on frames from about 166 to 221 lb, which are easier to fold and move.
Incline and Decline
Sole offers more incline. Every Sole from the F63 up reaches 15%, and the F50 12%. ProForm models reach 12%, or 10% on the Carbon TL. For steep incline walking, Sole gives you more range at every level above its entry model.
Only Sole offers decline in this matchup: the F89 and TT8 go down to 6%, which lets you train for downhill sections of a course. None of the ProForm models in our catalog has decline.
ProForm answers with automation. With an iFIT membership, compatible ProForm treadmills change speed and incline to follow a trainer or a mapped route. On Sole, apps that support Bluetooth control can do the same on supported models, without a required plan. See our best treadmill with incline guide for the strongest picks.
Pro tip: If you train for hilly races, the Sole F89 and TT8 cover 21 percentage points of grade, from 6% decline to 15% incline.
Consoles, Apps and Subscriptions
ProForm is built around iFIT. The Carbon models use small LCDs and stream classes to your own phone or tablet, while the Pro 2000 and Pro 9000 show them on built-in touchscreens. Without a membership, the treadmill still runs in manual mode with onboard workouts, but you lose the classes and automatic adjustments.
Sole takes the opposite approach. The F50, F63 and F65 use LED consoles with built-in programs; the F80 and F83 have 10.1-inch touchscreens, the F85 15.6 inches and the F89 21.5 inches. The SOLE+ app is free, and the consoles connect to third-party apps over Bluetooth, so nothing is required.
The choice is simple. If trainer-led classes keep you on the treadmill, ProForm delivers them for the price of iFIT. If you follow your own plan or already pay for an app, Sole avoids a second recurring cost.
Watch out: Budget for iFIT if classes are the reason you buy a ProForm. A touchscreen without the membership is mostly a manual treadmill with a large display.
Warranty, Build and Support
Warranty is Sole’s biggest advantage. Every current Sole in our catalog lists lifetime frame and motor coverage, with 1 to 3 years on parts and 1 year on labor. ProForm lists 2 years on frame, motor, parts and labor on the Pro 9000 and Pro 2000, and a 10-year frame with 1 year on motor, parts and labor on the Carbon line.
Build follows the same pattern. Sole frames are heavier, up to 314 lb on the F89, and the TT8 does not fold. Every ProForm in our catalog folds, and the lighter Carbon models are easier to place in an apartment.
The FTC advises checking what a warranty covers and for how long, and whether you pay for labor or for shipping parts. If a part is not listed, assume it is not covered.
| Model | Frame | Motor | Parts | Labor |
|---|---|---|---|---|
| Sole F80, F83, F85, F89, TT8 | Lifetime | Lifetime | 3 years | 1 year |
| Sole F63, F65 | Lifetime | Lifetime | 2 years | 1 year |
| Sole F50 | Lifetime | Lifetime | 1 year | 1 year |
| ProForm Pro 9000, Pro 2000 | 2 years | 2 years | 2 years | 2 years |
| ProForm Carbon TL, TLS, TLX | 10 years | 1 year | 1 year | 1 year |
