Head-to-Head Specs
Here are the two models side by side, from the Amazon US listings of the 2026 models and Sole’s warranty page. A check mark shows the stronger spec on each line. Before you order either model, search the CPSC recall database: the U.S. Consumer Product Safety Commission lists treadmill recalls and the fix offered. The American Heart Association recommends at least 150 minutes of moderate or 75 minutes of vigorous aerobic activity a week. If you train for road races, a 1996 study of trained runners found that a 1% incline best matched the energy cost of outdoor running at about 6.5 to 11 mph.

FitScore Duel
Both scores use the weights of our best treadmill with heart rate monitor guide: features 30%, performance 20%, durability and comfort 15% each, practicality and affordability 10% each. Heart rate training depends on sensor support, heart rate programs and a console that shows the data clearly, so features weigh most. Both treadmills score 92 on performance; the F80 pulls ahead on features (91 to 73), durability and comfort, while the F63 wins practicality and affordability. The F63 is not in that guide’s top 5, so its score simply uses the same weights.
Key Differences
- The F80 has a 10.1-inch touchscreen; the F63 has a 4-window LED display with dials in the hand grips.
- The F80 lists 20 programs; the F63 lists 10 preset, 2 user and 2 heart rate programs. Both have two heart rate control programs.
- The F80 is rated for 350 lb; the F63 for 325 lb.
- The F63 is 36 lb lighter and 2 × 2 inches smaller on the floor when assembled.
- Both carry lifetime frame and motor coverage; the F80 adds a year on parts (3 years against 2).
Round 1 of 5
Sole F63 vs F80: Motor, Speed and Incline
Sole F80 wins this round
Both run from 0.5 to 12 mph and climb to 15% under motor control, so they handle the same walks, hill sessions and steady runs.
The F80 lists a 3.25 HP motor and the F63 a 3 HP brushless motor. For walking, jogging and incline work, that gap is small; testers of the 2026 F63 noticed slight shaking at high speed on a steep incline, so the F80 is the steadier choice for faster running.
Round 2 of 5
Running Deck and Cushioning
Tie. Neither model has a clear edge here.
Both list a 20 × 60-inch running surface with an 18 mm cushioned deck on the F80 and a cushioned deck of the same thickness on the F63, per its listing.
Testers of the 2026 F63 found the deck roomy for runners up to about 6 feet. Testers of earlier F80 generations described a firm, road-like feel. Expect a solid rather than bouncy surface on either.
Round 3 of 5
Console, Programs and Heart Rate
Sole F80 wins this round
The F80’s 10.1-inch touchscreen shows your workout and heart rate data on a larger display and offers 20 programs, including fitness tests. The F63’s LED windows show speed, incline, time, distance, calories and heart rate, with speed and incline dials in the hand grips.
Both support Bluetooth heart rate monitors and include two heart rate control programs that adjust the workout to stay in a target zone. The larger screen makes zone training easier to follow, which is why the F80 leads our heart rate guide.
Round 4 of 5
Footprint, Folding and Weight
Sole F63 wins this round
The F63 needs about 75 × 34 inches of floor and weighs 187 lb; the F80 needs 77 × 36 inches and weighs 223 lb. Both fold with hydraulic assist and roll on wheels.
Folded, the F63 takes less floor (42 × 34 inches against 48 × 36) but stands 5 inches taller (71 against 66 inches). Check your ceiling and doorways before choosing.
Round 5 of 5
Warranty and Support
Sole F80 wins this round
Both list a lifetime frame and motor warranty and 1 year on labor, from Sole.
The F80 covers parts for 3 years against 2 for the F63, a small but real edge on a treadmill you plan to keep for years.
Consider Instead
Sole F65

Final Verdict
The Sole F80 is the better pick if you will use the touchscreen, the extra programs or the higher weight rating, especially for heart rate training. If you mostly walk on an incline or jog at steady paces, the Sole F63 gives you the same speed range, 15% incline, 60-inch deck and lifetime frame and motor coverage in a lighter, smaller frame.
