Sole F50 FitScore
FitScore rates each treadmill on six categories from structured product data, weighted for one buying intent. The F50 is bought mainly by value-focused buyers, so its score uses the weights of our best treadmill under $1000 guide, although it is not ranked there. Affordability counts most (35%), then performance (20%) and durability (15%), with comfort, practicality and features at 10% each, because value buyers want the most capable and longest-lasting machine for what they spend.
FitScore for Value Buyers
How this FitScore was calculated
This FitScore combines 6 category scores using the weights of the buying intent above.
- Affordability (82): a mid-range value pick within the guide.
- Performance (74): 12% incline, held back by a 2 HP motor and 10 mph top speed.
- Durability (70): lifetime frame and motor, 1-year parts and labor.
- Practicality (75): folding frame with a low 49-inch assembled height.
- Comfort (65) and features (66): cushioned 55-inch deck; LED console with 12 programs and the SOLE+ app.
Design and Build Quality
The Sole F50 uses an alloy steel frame with a 20 × 55-inch deck and a fold-up design. At about 180 lb, it is lighter than every rival in our comparison, and the assembled height of about 49 inches keeps it low in a room.
Sole backs the frame and motor for life, which signals confidence in the core components.
Bottom line: a compact frame with long coverage on the core parts.
Motor and Walking Performance
The 2 HP motor runs from 0.5 to 10 mph. That covers walking, brisk walking and steady jogging, but it is the smallest motor among the rivals in our comparison.
If you plan to run regularly, the Horizon 7.0 AT offers 3.0 CHP, 12 mph and a 60-inch deck.
Bottom line: best for walkers and light joggers.
Deck and Cushioning
The 18 mm Cushion-Flex deck is designed to soften each step. The 20-inch width is standard and leaves room to walk naturally.
At 55 inches, the deck suits walking strides. Taller users who jog may find it short.
Bottom line: comfortable for walking; short for running strides.
Incline and Programs
Powered incline goes up to 12%, steeper than the 10% maximum on the similar-size XTERRA TR65 and useful for steep hill walking that raises effort without more speed.
Twelve built-in programs give you structured workouts without an app.
Bottom line: the incline range is a highlight.
Console, Apps and Bluetooth
The LED console keeps things simple, and Bluetooth connects the treadmill to the SOLE+ app for tracking your workouts.
There is no touchscreen or built-in class library. If you want trainer-led workouts on the machine, the ProForm Carbon TLX runs iFIT (membership required).
Bottom line: simple controls, with the app as an add-on.
Footprint and Folding
Assembled, it needs about 70 × 34 inches of floor space. Folded, it shrinks to about 39 inches deep and stands about 62 inches tall.
A mat under the frame helps in apartments and upstairs rooms.
Bottom line: a good fit for smaller rooms.
Assembly, Warranty and Support
At about 180 lb, plan on two people for delivery and setup.
The warranty covers the frame and motor for life and parts and labor for 1 year. That matches the Horizon 7.0 AT and Horizon T202 on frame and motor, though the Horizon 7.0 AT adds longer parts coverage.
Bottom line: strong core coverage for a compact treadmill.
