Abstract
A prosthetic foot includes a longitudinal foot body and a biasing unit. The foot body includes front and rear end portions, and a longitudinal cavity between the front and rear end portions and extending inwardly from an upper surface of the foot body. The biasing unit is mounted in the cavity and has first and second ends extending respectively toward the front and rear end portions. The foot body is deflectable to contract the cavity. The biasing unit is subjected to a compression force when the cavity contracts, and restores the foot body to a normal position when the compression force is relieved.
