Fig. 6From: Three-dimensional quantitative analysis of healthy foot shape: a proof of concept studyVisualization of the effect of shoe size on foot shape. The influence of shoe size on foot shape for females (purple box), and the influence of shoe size on foot shape for males (green box). For each group, the influence of shoe size is represented by color-mapped Euclidean distance computed between the foot shape obtained for μ+2 σ and the foot shape obtained for μ- 2σBack to article page
