These pictures show the distributuion of pressure on the ground. The
color scale on the left indicates "red" as the highest pressure and "blue"
is the lowest. The variance of colors shows the different pressures in
each location as the foot is maximally pronated (the foot is spread out
as much as it can). These pictures are of a left foot with the toes at
the top of the image.
The barefoot picture (on the left) shows an uneven distribution of pressure
across the ball of the foot as it is maximally pronated (spread out to
the ground). This foot carries its highest concentration of pressure toward
the inside of the foot (highest under the 1st metatarsal and significant
pressure under metatarsals 2 & 3) with focal points of high pressure
under metatarsals 4 & 5.
The middle picture with the patient's own traditional orthotic does
reduce the pressure (compared to the barefoot).
The last picture on the right (with the SDO) in my opinion shows the
best distribution of pressure and best balance for this foot.
