The Sole TT8 treadmill reviews you find online agree on the core facts. It is a heavy, non-folding home treadmill with a 4.0 HP motor, a 22 by 60 inch belt, and a 400 pound weight capacity, selling for roughly $2,800. We rate it 86 out of 100. It is a strong buy if you are a heavier user or a regular runner who wants a machine that feels planted. It is a poor buy if you want a big screen, live classes, or a folding frame.
The Sole Fitness TT8 is one of Sole’s top treadmills and one of the most talked-about models under $3,000. Dyaco, the parent company behind Spirit, makes it, and it sells well at big-box stores. Sole puts its budget into the frame, motor, and deck, and leaves interactive tech to other brands. That choice explains why owners love it and why some reviewers call it overpriced.
We buy every treadmill we review and test it ourselves. The sections below cover why TT8 reviews disagree, how to judge its build, motor, and deck, where it falls short, how it compares with the NordicTrack X24, the Sole F80, and others, and how to decide before you order.
Why Sole TT8 reviews disagree so much
Reviews of the TT8 disagree because buyers judge a $2,800 treadmill by different yardsticks. Runners and heavier users praise the frame and motor. Buyers who want screens, classes, and a long warranty call it overpriced. Both groups describe the same machine accurately, so the useful question is which group you belong to.
Who gets the most from the TT8
Heavy users and serious runners get the most out of it. The TT8 carries a 400 pound weight capacity, and it feels like it can handle that load, with no rattling and no cheap wobble when you run. The motor is strong, consistent, and quiet for a home treadmill, which matters if you train before the rest of the house wakes up.
The TT8 suits you if you:
- Need a high weight capacity and a stable frame
- Run, or do speed and incline work, on a regular schedule
- Want a treadmill that works without a subscription or a login
- Have a dedicated spot for a machine that does not fold
- Prefer to buy from a big-box retailer or straight from Sole
The TT8 is a build-first treadmill: you pay for steel, motor, and belt, not for a screen.
Who should look elsewhere
Casual walkers will not use what they are paying for. A $2,800 price tag makes little sense if you walk 30 minutes a day, and a cheaper treadmill will serve you well. The same goes for buyers who want a folding frame or who live in a small space.
Skip the TT8 if you:
- Want live classes or trainer-controlled speed and incline
- Need to fold the treadmill away after each workout
- Are working with a budget closer to $2,000 than $3,000
Is Sole a good treadmill brand?
Sole is a good brand if you value durability over technology. It builds treadmills in almost every price range, and its models share the same construction approach, so a sturdy frame and a quiet motor are what you get even on cheaper machines. Our review of the Sole F80 at $1,899 points to the same stable, quiet feel.
The tradeoff is that Sole does not chase the app ecosystems that NordicTrack and ProForm sell. If that is a dealbreaker, you will read the TT8 as a letdown. If not, you will read it as honest engineering.
How to judge the TT8 on build, motor, and deck
Judge any treadmill on five things: the frame, the motor, the belt and deck, the incline range, and the console. Here is how the TT8 scores on each, starting with the numbers.
The TT8 specs at a glance
The table below collects the specs that matter most. Sole counts incline and decline in levels, and testers have noted that the levels do not always match exact percentages, though they stay consistent through a workout.
| Spec | Sole TT8 |
|---|---|
| Motor | 4.0 HP DC |
| Belt | 22" x 60" |
| Rollers | 3" |
| Top speed | 12 mph |
| Incline and decline | Up to 15% and down to -6% (15 incline levels, 6 decline levels) |
| Weight capacity | 400 lbs |
| Machine weight | About 325 lbs |
| Dimensions | 82.5" L x 38" W x 66" H |
| Step-up height | 8" |
| Console | 15.6" touchscreen, Bluetooth speakers, USB port, tablet holder |
| Folding | No, with transport wheels |
| Price | About $2,800 to $2,900 depending on seller |
Frame and build quality
The frame is the TT8’s best feature. It is solid, heavy, and stable, and the weight is part of the reason. At about 325 pounds, it does not shake when a heavy runner hits full stride. The low 8 inch step-up height also makes it easy to step on and off, which helps anyone with limited mobility.
Motor, belt, and deck
The 4.0 HP motor pulls the belt up to 12 mph without strain, and the 3 inch rollers sit at the upper end of what home treadmills use. Larger rollers help the belt stay aligned and ease stress on the motor. The deck is reversible, so you can flip it if one side wears.
The belt measures 22 by 60 inches, wider than the 20 inch belt on many home treadmills. Taller users and runners with a long stride will not feel cramped. The deck cushioning is on the firm side. It does not feel brutal, but if you want plush orthopedic softness, you will not get it here.
Incline and decline
The TT8 goes from -6% decline to 15% incline. Fifteen percent is plenty for serious hill work. The decline is the odd part. Most treadmills skip it, because decline is harder on the motor and on most users’ knees. On our unit, the decline felt a little skippy and was not as smooth as the incline. It works, but treat it as a bonus and not a selling point.
Console and tech
The console has a 15.6 inch touchscreen, 10 built-in programs plus two custom slots, Bluetooth speakers, a USB port, and a tablet holder. Pulse grips are built into the handlebars, and chest straps pair over Bluetooth. It does not connect to iFIT or Peloton. You can sync workout stats to a Bluetooth device, or stream your own content on a tablet. Nothing requires a subscription.
Judge the TT8 on frame, motor, and belt first, because that is where Sole spends your money.
Where the Sole TT8 falls short
The TT8’s drawbacks are its price against its feature list, a warranty shorter than Sole used to offer, a firm deck, a tall motor hood, and a large console. None of these breaks the machine, but each can break the deal for the wrong buyer.
Price and warranty
At roughly $2,800, the TT8 competes with specialty-store brands, yet its warranty has shrunk. Our review lists 3 years on parts and 1 year of labor. Other published listings show lifetime coverage on the frame and motor with different terms for the deck and electronics, so coverage may differ by seller and model year. Get the exact terms in writing before you pay.
We think the price is fair for a heavy user or a runner who will put thousands of miles on it. For a walker, it is not.
Comfort and fit on the belt
The motor cover is a bubble that sticks out and sits close to the front of the running area. If you creep forward as you run, you will notice it. Running a little further back on the belt solves it, but you should know before you buy.
Then there is the firm deck. Runners who want the treadmill to feel like outdoor pavement will like it. Anyone who wants a softer landing for sore joints should test it first or look at a more cushioned model.
Size, weight, and the console
The TT8 does not fold, and at 82.5 inches long it needs a dedicated space. Plan on leaving it where you put it. The transport wheels help for small moves, but a 325 pound machine is not something one person relocates casually.
The upper console is also big. If a wall-mounted TV sits in front of your treadmill, the console may block part of your view. The button layout adds a small annoyance. Some preset buttons jump in steps of two or three, so you use the manual buttons for exact speed and incline.
Most TT8 complaints are about fit and expectations, not failures, which is why measuring your space and your needs beats reading another review.
Sole TT8 vs NordicTrack X24, Sole F80, and others
The TT8 beats the NordicTrack X24 on price and simplicity and loses on incline and tech. Against Sole’s own F80 and F85, it wins on motor and build and costs more. Against the Spirit XT685 it is nearly even on paper.
Side-by-side specs
The X24 figures come from published specs for the 2025 model. The XT685 figures come from our own listing of that treadmill.
| Spec | Sole TT8 | NordicTrack X24 | Spirit XT685 |
|---|---|---|---|
| Price | About $2,800 to $2,900 | $3,999 | $2,999 |
| Motor | 4.0 HP | 4.25 CHP | 4 HP |
| Belt | 22" x 60" | 22" x 60" | 22" x 60" |
| Incline | -6% to 15% | -6% to 40% | Up to 15% |
| Top speed | 12 mph | 12 mph | 12 mph |
| Weight | About 325 lbs | 445 lbs | 277 lbs |
| Warranty | 3 yrs parts, 1 yr labor (see above) | Lifetime motor, 10 yr frame, 2 yr parts, 1 yr labor | 10 yrs parts, 1 yr in-home labor (residential) |
TT8 vs NordicTrack X24
Is Sole better than NordicTrack? It depends on what you want. The X24 offers a 40% incline, a 24 inch touchscreen, and iFIT trainer control. The TT8 offers a similar belt and speed with no subscription needed and about $1,000 less upfront.
Here is a worked example. Say you buy the X24 at $3,999 and pay about $39 a month for iFIT for five years. That is $468 a year, or $2,340, for a total of $6,339. The TT8 at $2,800 with no subscription costs $3,539 less over those five years. You can skip iFIT, but then the X24 runs in manual mode and you lose what you paid extra for.
If you want NordicTrack at the TT8’s price, our review of the 2450 Commercial lists $2,799, a 300 pound capacity, and a $40 monthly iFIT fee. That capacity is below the TT8’s, which matters for bigger users.
TT8 vs Sole F80 and F85
The F80 and F85 are Sole’s step-down models for casual and average runners. The F80 costs $1,899 and carries the same 3 years of parts and 1 year of labor we list for the TT8. It is a good pick for bigger users under $2,000, with a stable Z-shaped frame and a quiet feel.
Choose the TT8 if you run hard, train often, or want the stronger motor and wider range of features. Choose the F80 or F85 if you walk or jog a few times a week and would rather keep $900 or so in your pocket. Our Sole treadmill comparison chart scores the whole family side by side.
TT8 vs Spirit XT685 and the Elite Runner
The Spirit XT685 treadmill matches the TT8 on motor, rollers, belt, and speed. It costs about $200 more and carries a 10 year parts warranty, which is the clearest reason to consider it. At the top end, the 3G Cardio Elite Runner at $4,250 scored 95 out of 100 in our testing and carries a 10 year residential warranty with 2 years of in-home labor. Read the full Elite Runner review if the TT8 feels like a step short of what you want.
Against the X24 the TT8 is the simpler, cheaper machine, and against the XT685 the real question is warranty.
How to decide if the TT8 is worth buying
The TT8 is worth buying if your body weight, running volume, and space match what it does well, and if you can confirm the warranty and return terms before paying. Run the five checks below in order, and stop if any one fails.
Run the five-point check
Start with your use, because it decides everything else. Then measure and plan.
- Match your use. If you run or train several days a week, or need the 400 pound capacity, the TT8 earns its price. If you mostly walk, price a cheaper model.
- Measure your space. Allow 82.5 inches of length and 38 inches of width, plus room behind the belt. Stand on the deck at full incline and check the clearance above your head.
- Check your tech needs. If you want trainer-led classes, look at an iFIT model. If you stream on a tablet, the TT8’s holder is enough.
- Confirm the warranty in writing. Ask the seller for parts, labor, frame, and motor terms for the exact model year you are buying.
- Know the return window. A treadmill this heavy is a hassle to send back, so confirm the policy and who covers pickup.
Plan delivery and assembly
Delivery and assembly deserve their own plan. The TT8 weighs about 325 pounds and does not fold, so check that doorways, hallways, and stairs can take it. Budget two to three hours to assemble it and bring a helper, or pay for a delivery service that includes assembly. Assembly fees and delivery options vary by seller, so ask before you order.
Where to buy
You can buy the TT8 from Sole directly or from big-box retailers such as Dick’s Sporting Goods. Prices vary by seller and by season, so compare before you pay. Use our treadmill buying guide if you want a broader checklist on budget, motor, and after-sale service.
If the TT8 passes all five checks, buy it for the build and ignore the noise in the star ratings.
Our verdict on the Sole TT8
The Sole TT8 is a heavy, stable, quiet treadmill with a big belt, a strong motor, and a 400 pound capacity. It trades tech and a long warranty for build quality. It fits heavier users and serious runners with room for a non-folding machine. It does not fit walkers, small spaces, or anyone who wants app-driven classes.
If you are still weighing it against the NordicTrack X24, the Sole F80, or the Spirit XT685, compare the TT8 against every treadmill we have tested and pick the one that fits your weight, space, and budget.
