Three arches: medial & lateral longitudinal, and transverse (anterior/posterior). Keystone bones: talus (medial longitudinal), cuboid (lateral), intermediate cuneiform (transverse). Static supports: plantar fascia (central band), spring ligament, long/short plantar ligaments, interosseous ligaments. Dynamic supports: tibialis posterior/anterior, peroneus longus, FHL/FDL, intrinsic plantar muscles via windlass mechanism. Functions: shock absorption, distribution of load across hindfoot–midfoot–forefoot, energy storage/return in gait. Clinical: pes planus (flexible vs rigid; PTTD), pes cavus (neuromuscular); tests—Jack’s, Hubscher, Coleman block. Radiology: Meary’s angle, calcaneal pitch, talo‑navicular coverage, talo‑first MT angle; weight‑bearing X‑rays essential. Surgical principles: correct hindfoot alignment first, then forefoot; preserve/restore spring ligament and tibialis posterior function.
