Humans have modified non-opposable hallux. We have a large gluteus maximus for walking, hyperextended knees, short face, narrow trunk, short hips. Foot contains longitudinal and transverse arches for walking- they spread weight. Medial side of the longitudinal arch is more effective than the lateral side; is formed out of calcaneus, talus, navicular, 3 cuneiforms, 3 metatarsals. Lateral longitudinal is made of calcaneus, cuboidal and lateral two metatarsals. Foot is more of a flexible lever system than an arch.
