The adult model Air-Trekker jumping stilt features a padded knee bar that you slip you foot and leg through. The knee bar rests just below you knee cap. Although nothing needs to be added to begin jumping, many have found that adding some padding to the knee bar, creates a much tighter fit around the upper calf. A tighter fit gives the jumper more stability and confidence.
