1. Distribution of pressure at 20% of the stance phase of gait for a representative control boy (A) and a representative boy with Sever’s disease (B). The scale at the bottom indicates pressure (g/cm²). The white lines show the COP for each group. 2. Distribution of pressure at 35% of the stance phase of gait for a representative control boy (A) and a representative boy with Sever’s disease (B). The scale at the bottom indicates pressure (g/cm²). The white lines show the COP for each group. Figure 3. Distribution of pressure at 92% of the stance phase of gait for a representative control boy (A) and a representative boy with Sever’s disease (B). The scale at the bottom indicates pressure (g/cm²). The white lines show the COP for each group
