Fig. 2 (Top) Graph depicting adequacy index (ordinate) vs number of clusters (abscissa) indicating that the two-cluster solution is appropriate. (Bottom) Bivariate scatter plots showing two-cluster solution obtained using the following features: average pressure in heel (h_avgp), medial midfoot (mmid_avgp), lateral midfoot (lmid_avgp), medial forefoot (mfore_avgp), lateral forefoot (lfo_avgp), great toe (halx_avgp).
