Data are mean ± SD degrees. Positive values indicate hindfoot inversion, forefoot dorsiflexion, and forefoot adduction. First rocker, 0%–20% of stance; second rocker, 20%–80% of stance; third rocker, 80%–100% of stance. The 2SEM values were 1.2° for hindfoot eversion/inversion, 1.2° for forefoot plantar flexion/dorsiflexion, and 0.5° for forefoot abduction/adduction.
