Horizontal knee relative positions to pelvis during running. These positions described as percentage of leg length (%LL). The red circles and the red squares represent right and left heel strikes, respectively. The arrows represent the direction of motions. This figure demonstrates that runner with 20 mm thick and 30 mm thick blocks makes knees shift in lateral direction for avoiding blocks’ collision
