Sole F63 vs Horizon 7.0 AT: Which Treadmill Should You Buy?

If you’ve narrowed your home treadmill search down to these two, you’re not alone — the Sole F63 and Horizon 7.0 AT are two of the most recommended machines in the $999 mid-range category, and on paper, they look nearly identical. That similarity is exactly what makes this a hard decision, and exactly what this article is here to untangle.

Quick answer: For most buyers, the Horizon 7.0 AT is the stronger overall pick, thanks to its console and cushioning refinements — but the Sole F63 is the better choice if you want more onboard programs, a bundled heart rate strap, or you primarily train at a steady pace rather than doing intervals. I’ll break down exactly why below.

Sole F63 vs Horizon 7.0 AT: My Pick

If this were going in my own home gym, I’d choose the Horizon 7.0 AT — and not just because of the spec sheet. As a trainer, the thing I actually weigh most heavily is how a machine behaves when a client’s workout gets unpredictable: pace changes, incline surprises, the moments training doesn’t go exactly to plan.

The QuickDial console handles that better than a standard button layout does, and that’s the kind of small friction that determines whether someone sticks with a training plan long-term, not just whether the treadmill looks good in a spec table. That said, I want to be upfront that this is a close call — the Sole F63 is a legitimately strong machine for a different kind of buyer, and I’ll show you exactly where it wins below so you can weigh it against your own training style, not just take my word for it.

Where They’re Identical

Before getting into what separates these two, it’s worth being upfront: on the specs that most buyers check first, there’s no difference at all. Both machines run a 3.0 HP motor, a 20″ x 60″ running surface, a 15% max incline, a 325 lb weight capacity, and a lifetime frame and motor warranty.

If you’re comparing these two purely on a spec sheet, you’d have no reason to choose one over the other — which is exactly why the real decision comes down to details the spec sheet doesn’t show.

Cushioning: Same Promise, Different Engineering

Both brands claim strong joint protection, but they get there differently.

The Sole F63 uses what it calls a Cushion Flex Whisper Deck, which spreads cushioning evenly across the entire running surface. The feel is consistent no matter where your foot lands.

The Horizon 7.0 AT uses a three-zone cushioning system instead — softer support where your foot strikes at the front of the belt, and firmer support toward the back for push-off.

Why this matters: if you’re a heel-striker, or you run longer distances, the Horizon’s front-loaded cushioning tends to feel noticeably better under the joints. If you prefer a flatter, more predictable ground feel regardless of foot placement, the Sole’s even cushioning profile may suit you better.

Rollers and Build Durability

The Sole F63 uses larger-diameter rollers than the Horizon 7.0 AT. Larger rollers generally run cooler and hold up better under frequent, heavy use — a meaningful consideration if you plan to run on the machine daily rather than use it a few times a week.

Console and Onboard Programs

This is where the two machines diverge in philosophy. The Sole F63 ships with 10 built-in workout programs, giving you more structured, guided options if you train alone and like pre-set variety.

The Horizon 7.0 AT trades some of that program variety for a QuickDial, letting you adjust speed and incline on the fly without stopping your workout or reaching for buttons.

What’s in the Box

The Sole F63 includes a chest strap heart rate monitor in the box. The Horizon 7.0 AT relies on handlebar sensors instead, and you’d need to buy a chest strap separately if you want more accurate heart rate tracking. It’s a small cost difference, but worth factoring into your total spend if heart rate training matters to you.

What Independent Testers Found

Rather than just giving you my opinion, I checked what hands-on testers at established outlets actually found after putting each machine through real workouts.

On the Sole F63, testers at both Garage Gym Reviews and BarBend — including a certified personal trainer and a collegiate strength and conditioning coach — independently noted some shakiness and wobble at the F63’s top speed. It wasn’t described as a dealbreaker, but it’s a real, repeated observation from two separate testing teams, and it points toward the F63 being better suited to steady, moderate-pace training than to full-speed sprint work.

On the Horizon 7.0 AT, Garage Gym Reviews’ testing team rated it a perfect 5 out of 5 for its speed and incline responsiveness, and Forbes Vetted’s reviewer — after testing it directly — positioned it as a front-runner in the entire under-$1,000 treadmill category. That responsiveness lines up with what the QuickDial console adds in practice: quicker, steadier control exactly when you’re changing pace fast, which is what interval training demands.

Put together, this is a case where independent testing and the hardware differences point the same direction: the Horizon 7.0 AT holds up better under fast, variable-pace work, while the Sole F63 is the more confident pick if most of your training is steady-paced. That tracks with what I see coaching clients, too — a machine that stays smooth and controllable through pace changes is the one people actually keep using six months in, not just the one that looks better on a spec sheet.

The mechanism behind this is worth spelling out rather than leaving as a vague impression: the Horizon’s motor adjusts to speed and incline changes noticeably faster than the F63’s, which is exactly what interval work demands — quick, confident transitions rather than a lag between input and response. That same faster response is a non-issue for steady-state training, where you’re rarely changing pace anyway, so it doesn’t tip the scale for treadmill walkers or steady runners. If you have any balance sensitivity, the F63’s slower, more gradual pace changes can actually work in your favor rather than against you.

Build quality has a wrinkle worth being upfront about, too, since it doesn’t fall entirely on one side. The F63’s top-speed wobble noted above is a belt/frame issue at full sprint pace. The Horizon has a different quirk: its console can shake slightly during a run, something Sole addressed on the F63 with a steel crossbar between the uprights specifically to keep the console steady. Neither issue is a dealbreaker on its own, but it’s more honest to flag that each machine has a stability quirk in a different place than to imply only one of them does.

One more practical note that doesn’t show up on a spec sheet: both treadmills’ built-in fans and speakers are on the weak side. If ambient noise or airflow matters to your workouts, plan on using your own fan and Bluetooth speaker rather than relying on either console’s.

Handling and Storability

If you’re folding this treadmill up regularly rather than leaving it permanently set up, the day-to-day handling differs more than the spec sheet suggests. The Sole F63 has four transport wheels, so you can push it into a corner without tilting it. The Horizon 7.0 AT has two transport wheels, meaning you have to tip it back onto them to move it — a small thing, but one that matters if you’re moving the machine often in a smaller space or don’t want to wrestle with a ~250+ lb treadmill solo.

Footprint-wise, they’re close: the F63 runs about 6 inches longer than the 7.0 AT, while the Horizon is roughly 20-25 lbs heavier fully assembled. Neither difference is large enough to be a dealbreaker on its own, but worth a quick measure of your space before you buy either one.

App and Ecosystem Compatibility

Neither treadmill includes a touchscreen or a built-in subscription — you’re using your own phone or tablet for streaming workouts on both. Where they differ is breadth of third-party app support: the Horizon 7.0 AT connects with a wider range of apps, including Zwift, Peloton’s app, and direct Apple Watch syncing. The Sole F63 leans more on its own ecosystem — it bundles a free trial of the Sole+ app, which includes thousands of on-demand workouts, with no required subscription after the trial if you’re happy using the built-in programs instead.

If you already have a favorite training app you don’t want to give up, check that it’s supported before buying — Horizon’s broader third-party compatibility matters more if your routine already lives inside a specific platform.

Warranty and Return Policy

Both treadmills carry a lifetime warranty on the frame and motor, which is genuinely excellent for this price range — but the coverage isn’t identical once you look past the headline. Sole backs the F63 with additional coverage on the deck, parts, and wear items beyond the lifetime frame/motor promise, while Horizon’s coverage on the 7.0 AT centers on the frame/motor lifetime warranty plus a standard multi-year parts and one-year labor term. If warranty depth matters to your decision, it’s worth pulling each brand’s current warranty page directly, since terms are revised periodically.

Return policies also work differently in practice. Both companies offer a 30-day satisfaction window, but the process isn’t identical: Sole has generally arranged pickup of returned units directly, while Horizon typically requires you to arrange and pay for return shipping yourself, with a possible restocking fee. If you’re on the fence about either machine, that difference is worth knowing before you buy, not after you decide to return it.

Both brands also offer 0% APR financing for qualifying buyers through third-party lenders — useful if you’d rather spread the cost than pay the full $999 upfront.

Other Treadmills Worth Considering

If neither of these ends up being the right fit, a few other machines regularly come up in the same budget-to-mid-range conversation: the NordicTrack T Series 10 (if you want iFit-style streaming), the ProForm Carbon TLX (a similar price point with a slightly different feature mix), and the Bowflex BXT8J (worth a look if you want more onboard programs out of the box). I may cover full comparisons of these against the F63 and 7.0 AT in future articles.
