ABSTRACT:
An article of footwear includes a sole, an upper portion, and an energy storage system. The upper portion includes a shell for enclosing a user's foot therein. The energy storage system extends between the upper portion and the sole and converts impact forces generated by the user at the heel portion of the shell into propulsion forces to thereby enhance the user's performance.
