Foot alignments influence the effect of knee adduction moment with lateral wedge insoles during gait

Highlights • We evaluate the immediate biomechanical effects of lateral wedge insoles during gait. • Lateral wedge insoles have a positive effect in the Normal foot group. • Reduction in the peak knee adduction moment was correlated with reduced lever arm. • The reduced lever arm was correlated with less hip adduction during gait. • The biomechanical effects vary according to the individual’s foot alignment.
