Who should pick which

Pick the Echelon Stride DuoTread if

  • you weigh more than about 210 lb. It is rated for 275 lb against 240 lb, and we suggest 30 lb of headroom above your weight.
  • you will move it in and out of storage often. It weighs 66.1 lb against 81 lb.
  • you want to walk uphill. It has incline up to 4.1%, while the WalkingPad X21 is flat.

Pick the WalkingPad X21 if

  • you are tall or walk briskly. Its 47.6-inch belt suits walkers up to about 7'2" at slow desk pace (6'0" with 6 inches of room to drift), and up to about 5'5" for brisk walking, against 6'4" at slow desk pace on the 43.3-inch belt.
  • you drift sideways while you read or type. A 18.1-inch belt gives more room than 15.7 inches.
  • storage space is tight. It folds (Yes, double fold); the other one does not fold its deck.

Our buying guides

How these pages are built

Every figure comes from the maker's product page, manual or the Amazon listing, and we only include models with a live, in-stock Amazon listing we checked ourselves. When sources disagree on a weight limit we use the lowest number. We do not test these machines ourselves.

Height fit starts from a typical walking step of 0.41 times your height (0.45 when walking briskly), adds 12 inches for your shoe, and 6 more inches of room to drift for a comfortable fit. These are rough guides, not measurements of you. Weight fit leaves 30 lb of headroom above your body weight.
