Top-down view of foot positions. Top-down view of foot positions from four steps of participant number 3. For both left and right foot, the step lengths (LSL and RSL respectively) are calculated using triangles obtained from the positions during stance and indicated in the left part of the figure. The CoM’ and its trajectory (blue) and the XCoM’ (green) together with the front line of the BoS, just before heel-off (pink) are shown on the right. The shortest distance from the XCoM’ to the front line of the BoS (in walking direction, to the right in this figure) is calculated (DSM) and indicated in the figure with a black line
