Oh, I forgot that the scale dials might be hidden in the conformers. Thanks for reminding me pjz99. Below is the text of a pz2 (pose) file that will unhide the scale channels in the shins. If the shoes are two separate figures apply the pose to both.

                scale scale
                        {
                        hidden 0
                        }
                scaleX xScale
                        {
                        hidden 0
                        }

                        {
                        hidden 0
                        }
                scaleZ zScale
                        {
                        hidden 0
                        }
                }
        }

        {
        hidden          0
        addToMenu       1
        channels
                {
                scale scale
                        {
                        hidden 0
                        }
                scaleX xScale
                        {
                        hidden 0
                        }
                scaleY yScale
                        {
                        hidden 0
                        }
                scaleZ zScale
                        {
                        hidden 0
                        }
                }
        }
}

After applying the pose, you may need to select a different actor, then reselect a shin in order to force an update of the parameters palette and display the scale dials. As an alternative to using the above, you could install "Show Scale Dials V4" from sharecg.com, and apply that to the shoes. As long as the shin actors themselves have not been hidden, it should do the job.
