Systems and devices for use as lower leg prosthetic devices that include a foot portion having anterior and posterior ends and a first surface having a protrusion that protrudes therefrom adjacent the posterior end of the foot portion, has a semispherical or hemispherical surface with a passage therethrough extending laterally relative to the foot portion. The systems and devices further include a toe portion pivotally coupled to the anterior end of the foot portion, and a plate portion configured to couple to an attachment device and thereby be functionally secured to a user. The plate portion has a recess configured to couple with the protrusion of the foot portion. A cylindrical rod is located within the lateral passage of the protrusion and has ends protruding therefrom on oppositely-disposed of the protrusion. The plate portion is pivotally coupled to the ends of the rod on oppositely-disposed lateral sides of the protrusion.
