Look and Feel Of The Treadmill
Materials – For the most part, these two treadmills seem to have the same materials used in their construction. All the materials are high-quality, such as the commercial-gauge steel frame and the minimal use of thick molded plastic. However, the hydraulic system on the F85 adds a layer of superiority. It allows users to more easily fold up the deck of the F85 and users can allow the deck to lower itself hands-free. As the S77 cannot fold, it lacks this helpful addition.
Category Winner – SOLE F85
Sturdiness – While we tested both treadmills, the F85 performed better under the running at incline tests we put it through. The S77 had a slight tendency to wobble a bit when operating at a higher incline as the tester ran.
Category Winner – SOLE F85
Moving the treadmill – Both of these treadmills are heavy, which makes the task of moving them difficult. However, the F85 can fold up and be rolled fairly easily while the S77 does not fold, making it tough to maneuver the treadmill, especially if you need to move the S77 through a doorway.
Category Winner – SOLE F85
Cushioning – These treadmills both come with Cushion Whisper Flex™ treadmill decks. However, the F85 has a slightly more flexible deck, which can be easier on sensitive feet.
Category Winner – SOLE F85
Assembly – As these two treadmills are constructed with many of the same materials, they take around the same amount of time to assemble.
