Measured foot morphological variables.

Variables	Definition	Source
Foot length (cm)	Measured from the most posterior point of the calcaneus to the distal end of the longest toe	Butler et al., 2008 [23]
Foot width (cm)	Measured from the first metatarsophalangeal joint to the fifth metatarsophalangeal joint	Zhao et al., 2017 [24]
Truncated foot length (cm)	Measured from the most posterior point of the calcaneus to the first metatarsophalangeal joint	Butler et al., 2008 [23]
Navicular height (cm)	Measured from the ground to the tuberosity of navicular bone	Mulligan et al., 2013 [25]
Dorsum height at 50% of the foot length (cm)	Obtained at 50% of foot length with a vertical caliper measured from the ground to the top of the dorsum	Mulligan et al., 2013 [25]
Arch height index (AHI)	Calculated as the dorsum height at 50% of the total foot length divided by truncated foot length	Williams et al., 2000 [21]
