Figure 3: Comparison of peak plantar pressure between the control (Cntrl) shoe, the
group-optimized design (apex position = 52%) and personalized apex design (PersApex)
in footwear with a rocker angle (RA) = 15° (a-c) and footwear with a RA = 20° (d-f) for the
three anatomical regions. The horizontal dotted line represents the 200 kPa threshold and
the horizontal bars denote a significant difference between the control shoe and group-
optimized design (p < 0.001).
