The relationships between foot print indices and physical performances are analysed on 18 male and 17 female students. The plantar area index corresponding to the "arch index" of Cavanagh and Rogers (1987) correlated with the plantar shape index that measures the roundness level of foot print configuration. Since two indices correlated with the plantar size parameters, it was suggested that the plantar shape is not independent from the size factor.
　The foot print indices did not correlate with the extent of sway in normal stance but show a slight correlation in one foot stance. The concave level on the sole may contribute the stability under unstable condition. The significant correlation is revealed between plantar indices and the results of the vertical jump, but not between the indices and the results of the side step.
