Figure 1.
Participants walked in 3 different immobilizing boots, 2 of which are shown above. The softshell wedge (row 2) and hardshell wedge boots use stacked foam wedges to position the ankle. We used a 64-mm wedge for 30° of plantarflexion, a 23.5-mm wedge for 15° of plantarflexion, and no wedges for 0° of plantarflexion (row 1). The hardshell posterior strut boot (row 3) was positioned at 30°, 20°, 10°, and 0° of plantarflexion. The interchangeable cam bottom was swapped out for a flat bottom at 10°.
