Sole S77 Treadmill Review

Sole S77 Treadmill Review

Last Updated: March 21, 2021

The answer to your intense running needs at home comes in the form of the Sole S77, built to power through hardcore workouts. It seems like a non-folding version of the widely popular F85, with few differences. Its huge weight capacity and impressive motor make it a superior choice among heavy-duty home treadmills. 

Here’s all you need to know about the S77:

  • 10.1-inch Graphic Display

While the S77 lacks the 2021 console upgrade of the F85, perhaps it’s for the better – it seems like the integrated Android touchscreen on the F85 needs quite a few bug fixes before we can get to use all the extra features. 

The 10.1-inch graphic display on the S77 is identical to the console LCD on the 2020 version of the F85. It displays your workout stats well enough, and there’s always the integrated tablet holder to use above it when you feel bored.

  • 4.0 HP Motor

Although it’s sold primarily as a home treadmill, the motor on the S77 is a solid 4.0 HP, enough to support multiple high-intensity workouts at top speeds. This is the main feature that makes it on par with commercial standards. 

A 4.0 HP motor is best for heavyweight athletes, and this is the primary factor that influences the S77’s price point aside from its sturdy construction. If you’re a casual home user with moderate weight, you can save money and go for some other option with a 3.5 HP motor. Those will work just as well for you.

  • The Largest Running Belt of all Sole Treadmills

That’s how it’s marketed, at least. In fact, the 56 x 152.5 cm running deck on the S77 is just as long and wide as the one on the F65 and F85 treadmills. These dimensions were enough for the tallest and broadest of us to stay comfortable with ample leg and elbow room. 

There’s also the cushioning technology, but we liked the F85 better in this regard. The Cushion Flex technology on Sole treadmills is still not as good as the NordicTrack and ProForm models’ cushioning features. It’s definitely a big improvement from road running, though. 

  • Multiple Workout Options

The workout programs on the S77 are similar to the ones on the F-series models. Manual mode, two heart rate programs, two custom options, and five preset workouts (fat burn, cardio, hill, etc.) are incorporated into the machine.

Besides the integrated programs, you can connect with the Sole App via your Apple or Android device and keep your workout stats in your preferred database (MyFitnessPal, FitBit, etc.) The Sole app also allows you to design your own training sessions.

We also love Kinomap, present on most Sole treadmills, including the S77. It’s a virtual running feature where you choose scenic routes on the map to explore the world, right from your treadmill deck! The S77 connects to the app via Bluetooth and automatically adjusts its incline according to your chosen path’s steepness for a realistic experience.

  • Up to 22 km/h speed and 15% Incline Limit

The max speed is as good as it gets and coupled with a motor that actually supports high speeds. As a result, you can be ambitious about your running goals with the S77. 

The 15% incline limit further adds a strength training component to your run besides enabling multiplied calorie burn.

  • Dual Heart Rate Monitoring Features

The S77 not only has pulse sensing handlebars but also gives you the option of wireless heart rate monitoring via the included Bluetooth chest strap.

  • Other Features 

We love the smaller perks too, like cooling fans, Bluetooth speakers, USB charging, and dual storage holders.

  • No folding option

  • Weaker cushioning than we expected
  • Difficult to relocate
  • Mixed views on customer support

Warranty Summary

The Sole S77 comes with:

  • Lifetime warranty on frame, motor, and deck
  • 5-year parts warranty
  • 2-year labour warranty

Bottom Line

In case you’re on the lookout for a commercial-standard treadmill for home use, the Sole S77 has a great combination of features to make it a worthwhile purchase. While it lacks a folding option, it does have a sturdy construction, more than enough motor power, and everything you need for optimal functionality and durability, all at a lesser price than the foldable F85. 

On the contrary, we’d recommend you to save some cash and go for another option with lesser motor power if you’re in the moderate weight category and only need a treadmill for casual home use; even 3.5 HP motors work great for domestic treadmills.
