Significance of Pearson’s correlations coefficients is indicated as follows: *p < 0.05, **p < 0.01. ABDM abductor digiti minimi, ABH abductor hallucis brevis, ACSA_max maximal anatomical cross-sectional area, ADDH-OH adductor hallucis oblique head, ADDH-TH adductor hallucis transverse head, FDB flexor digitorum brevis, FDL flexor digitorum longus, FHB flexor hallucis brevis, FHL flexor hallucis longus, MV muscle volume, QP quadratus plantae
