Sole F50 Treadmill vs NordicTrack X16 Treadmill

The NordicTrack X16 is the stronger machine for serious training: a 400 lb capacity, 12 mph top speed, a 40% to -6% incline/decline range and a pivoting 16-inch touchscreen with iFIT. The Sole F50 is the simpler, quieter choice for walking and light jogging, with a brushless motor, a 20 x 55 inch deck and 12 incline levels. Reviewers rate the X16 highly for its build and incline range; the F50 is known as a sturdy, low-maintenance basic.

• Choose the Sole F50 if you want a quiet, straightforward treadmill for walking and jogging and don't need a big touchscreen or steep incline.
• Choose the NordicTrack X16 if you want steep incline and decline training, a larger weight limit and a pivoting touchscreen with guided iFIT workouts.
