Sole F65 Treadmill Review

Sole's lineup has a clear budget option and a clear flagship, and the F65 sits in the middle doing the least glamorous but most important job: being the treadmill that just works for the widest range of households. After a month of daily testing across multiple runners and walkers, we think it's the one most people searching "Sole treadmill" should actually buy.

Overview and Who It's For

The F65 occupies an unusually well-defined spot in Sole's catalog. It costs meaningfully more than the entry-level F63, but instead of spending that extra money on flashy console features the way a lot of competitors do at this price point, Sole put it directly into the motor and deck — a stronger 3.5 CHP motor and a full 22 x 60-inch running surface, both of which are shared with the significantly pricier F80. That's the core reason we keep coming back to the F65 as our default recommendation: you're paying for hardware that matters every single run, not for a bigger screen you'll glance at occasionally.

We tested it against the exact question most shoppers land on this page asking: is the F65 worth roughly $400 more than the F63, or should you just save the money and go smaller? After a month of use, our answer is that it depends almost entirely on how you intend to use it. If you're walking a few times a week or jogging occasionally, the F63 will serve you fine. If you plan to run regularly, if more than one person in the household will use the machine, or if you simply want headroom so you're not shopping for another treadmill in two years, the F65 is worth the jump.

This is a folding treadmill, and Sole's hydraulic-assisted lift made raising and lowering the deck noticeably easier than we expected given the machine's weight. Folded, it stands at roughly 36 x 78 inches — smaller than NordicTrack's Commercial-tier machines, but still sized more like a semi-permanent home gym fixture than an ultra-compact apartment treadmill. If daily folding in a tight space is your top priority, it's worth cross-checking our folding treadmill guidefor machines built specifically around that use case.

We'd recommend the F65 most strongly to a household with a dedicated but modest amount of space — a spare room, a basement corner, a garage bay — that wants a single treadmill capable of handling everyone from a walking parent to a running teenager without anyone feeling like they've outgrown it.

Full Spec Sheet

Here's every spec we verified directly against our test unit rather than copying from the manufacturer's marketing page.

Assembly and Setup

Assembly took our team roughly 60 minutes working alone, faster than several competitors we've tested at this price, largely because the F65's upright posts arrive already attached to the base rather than requiring a separate lift-and-bolt step. A second person still helps with positioning the console assembly, but it's genuinely a one-person job if you have to do it that way.

The included tools covered the entire build, and Sole's manual uses clear numbered diagrams rather than dense text instructions, which our testers found easier to follow than some competitors' documentation. The unit ships in a heavy box — expect somewhere around 250 pounds including packaging — so plan a delivery and unboxing location you can actually work in rather than trying to haul the full crate up a narrow stairwell first.

Once assembled, we ran the same calibration pass we recommend for every new treadmill: cycle through the full incline range once, listen for unusual noise from the incline motor, and confirm the safety key stops the belt immediately when pulled. On the F65, that check turned up nothing to flag — the incline motor was smooth and quiet from the very first cycle, which isn't universal among machines in this price range.

Performance Deep Dive

Motor and Deck

The 3.5 CHP motor handled everything we threw at it without straining, including back-to-back interval sessions pushing past 7.5 mph. It's not quite as effortless at the top of its range as NordicTrack's larger 3.75 CHP unit in the Commercial 1750, but for the overwhelming majority of home runners — anyone training below a roughly 8-minute mile pace — the difference is academic. The 22 x 60-inch deck is the same size used on Sole's flagship F80, and it shows: our tallest tester, at 6'2", never felt cramped during full-stride running.

We also ran a 45-minute heat-soak test at a sustained 6 mph, checking motor housing temperature by hand every ten minutes. The housing warmed but never became uncomfortable to touch, and belt speed held consistent throughout without the surging some cheaper motors exhibit under sustained load. Belt tracking stayed centered across the entire test, never drifting toward either rail.

Cushioning

The Cushion Flex Whisper Deck system uses individually mounted cushions rather than one continuous pad underneath the belt, which lets Sole tune impact absorption differently at the heel-strike zone versus the push-off zone. In practice, this is genuinely noticeable — testers with knee sensitivity specifically called out how much softer the F65 felt during longer walking sessions compared to a flatter, single-pad deck on a cheaper machine, while the push-off zone stayed responsive enough that faster running didn't feel mushy or delayed.

Console and Everyday Usability

This is where the F65 draws its clearest line against touchscreen-first competitors, and it's worth being direct about it: the console is a straightforward LCD display showing speed, incline, time, distance, calories, and heart rate, with physical buttons for quick-adjust speed and incline changes on the handrails. There's no touchscreen, no built-in workout videos, and no subscription prompt. We consider this a genuine feature rather than a missing one — every function works fully on day one and stays that way for the life of the machine, with nothing that can be paywalled, discontinued, or slowed down by a server outage on the manufacturer's end. If you want streaming workout content, pair a tablet on the included media shelf; if you want the treadmill itself to hold you accountable with pre-programmed intervals and hill routines, the F65's built-in programs handle that without any app connection required.

Incline and Speed Response

Manual incline adjusts in clean 1% increments from 0% up to 15%, responding within a second or two of a button press rather than the slower ramp we've measured on some budget machines. Speed changes are similarly quick and precise in half-mph increments, which matters more than it sounds like during interval training where you're changing pace every 30 to 60 seconds — a sluggish response either leaves you jogging in place waiting for the belt to catch up or forces you to anticipate the change a few seconds early, and the F65 never put us in that position.

Noise and Vibration

We measured noise in the mid-to-high 50-decibel range during brisk walking and the low 60s during sustained jogging, which stayed consistent even after an hour of continuous use rather than creeping louder as the motor warmed up. Placed on a hard floor without a mat, we noticed some vibration transfer at higher speeds, which is common to nearly every treadmill in this weight class rather than specific to the F65 — a quality equipment mat underneath cut that transfer noticeably during our follow-up test, and it's a cheap upgrade we'd recommend regardless of which treadmill you end up buying.

Long-Term Durability Notes

Four weeks of hands-on testing can't fully answer a multi-year durability question on its own, so we cross-referenced our impressions against patterns in verified owner reviews spanning one to four years of ownership. The most consistent theme was positive: owners report the frame staying tight and rattle-free well past the two-year mark, which tracks with Sole's heavier steel construction and more welded (rather than purely bolted) joint design. Belt tracking came up as the most common maintenance item, with a subset of owners needing to re-center and re-tension the belt within the first year — normal treadmill upkeep rather than a defect, but worth budgeting a few minutes for periodically.

Sole's warranty coverage on the F65 is a real differentiator: a lifetime frame warranty, a 10-year motor warranty, and 2-year parts with 1-year labor coverage. That lifetime frame term in particular is stronger than what most competitors in this price range offer, and it's the kind of coverage a manufacturer only extends when confident the frame itself won't be the failure point. We'd recommend registering your unit promptly after delivery, since warranty claims process noticeably faster with registration already on file.

The motor housing on the F65 is fully enclosed, which owners consistently credit for both quieter long-term operation and less dust and debris accumulation around the drive belt compared to more open-frame budget machines. Keeping the belt lubricated on Sole's suggested schedule remains the single biggest factor in avoiding premature motor strain, a pattern that holds true across essentially every treadmill brand we've researched, not just this one.

One pattern worth flagging for anyone shopping across multiple Sole listings: because the F65 shares core components with the F80, including the same deck dimensions and a similar drive belt design, parts availability and repair familiarity among service technicians tend to be strong even outside the standard warranty window. Owners who've needed a belt or roller replacement several years in generally reported an easier time sourcing parts than they expected, which is a meaningful, if unglamorous, part of the total cost of ownership over the life of the machine.

Pros and Cons

How It Compares

The F65 doesn't exist in a vacuum — here's how it stacks up against its own budget sibling and the closest subscription-dependent rival at a similar price.

Stepping down to the Sole F63saves roughly $400 but trades away two inches of deck width and a half-CHP of motor power — fine for walkers, noticeably tighter for regular runners. The NordicTrack Commercial 1750 costs several hundred dollars more and adds a large touchscreen with iFit coaching, but requires an ongoing subscription to unlock most of what makes that screen worth having in the first place. If you know you don't want a subscription tied to your treadmill, the F65 delivers comparable core hardware for less money and no recurring bill.

It's also worth a mental comparison to Sole's own flagship, the F80, even though it isn't in the table above. The F80 shares the F65's 22 x 60-inch deck but adds a stronger 4.0 CHP motor and a larger, more modern console with app integration — a genuine step up for serious daily runners, but overkill for the moderate, few-times-a-week use case the F65 is built around. Unless you know you'll be running most days of the week, the F65 gives you nearly all of the F80's day-to-day comfort for meaningfully less money.

Who Should Skip This Treadmill

The F65 is our default recommendation in Sole's lineup, but it isn't the right machine for every shopper who lands on this page. If interactive, trainer-led coaching content with auto-adjusting incline is a must-have for you, the plain LCD console here will feel like a step backward — a NordicTrack or the Sole F80's more modern console will serve you better, even at a higher price. If you're a genuinely light user — walking occasionally rather than building a real routine — the F63 gets you Sole's build quality for $400 less, and you likely won't notice the smaller motor and deck. And if ultra-compact apartment storage is non-negotiable, its folded footprint, while smaller than NordicTrack's Commercial line, is still sized more like a permanent fixture; check ourfolding treadmill guidefor machines built specifically around tight storage.

Final Verdict

The Sole F65 earns its reputation as the treadmill most Sole owners actually recommend because it doesn't cut corners on the two things that matter most day to day: motor strength and deck comfort, delivered without a subscription tax. The plain console is a real trade-off, not a minor footnote, and if interactive coaching content is what you're after, you should shop elsewhere with eyes open. But judged purely as a piece of exercise equipment — motor, deck, frame, cushioning, warranty — this is a treadmill built to be used hard for years, not one built to look impressive in a product photo.

If you're still weighing the F65 against a short list of finalists, our advice mirrors what we'd say about any treadmill in this price range: buy based on the motor and deck you'll be living with every single workout, not the screen you might glance at occasionally. Screens age; a properly built frame and a full-size deck don't.
