The human body is imperfect and consequently, many cyclists experience pain and discomfort due to one leg that is longer than the other.  Cycling or bike riding amplifies leg length discrepancy discomfort through thousands of pedal revolutions.  Just a 1-hour ride at 80 revolutions per minute (RPM) equates to almost 5000 pedal strokes.

    Bought a set to try and solve some mild hip pain. Simple to use, affordable, and has held up fine so far.

    Unrelated to the product: I really love that it came packaged with no plastic. You would expect all the extra screws and such to come in single-use plastic bags that just eventually end up in the Pacific Ocean but nope. It also came with a sweet handwritten note. Thanks <3

    • Shimano recently changed their packaging to reduce the use of plastic. It’s great that a big company are leading by example, and nice of you to notice and comment.
