Claim 14:
15. A selectively height adjustable platform shoe assembly comprising a pair of articles of footwear, each article of footwear comprising:
a sole,
an upper attached to a top perimeter of the sole, such that the upper and the sole define a cavity configured for insertion of a respective foot of a user;
a recess extending into a lower face of the sole, the recess extending from proximate to a first end to proximate to a second end of the sole, the recess being substantially elliptical;
a plurality of nested rings attached to the sole and positioned in the recess, the plurality of nested rings comprising four nested rings, each nested ring having a height of 2.50 to 2.60 cm;
an actuator attached to the sole, operationally engaged to the plurality of nested rings, and being configured for selectively extending the nested rings from the recess, the actuator comprising:
a pump,
a reservoir in fluidic communication with the pump and containing hydraulic fluid,
a plurality of hydraulic cylinders, the plurality of hydraulic cylinders comprising hydraulic cylinders positioned singly at each opposed end of each nested ring, each hydraulic cylinder comprising a fixed section and a plurality of movable sections, the plurality of movable sections being numerically equivalent to the plurality of nested rings, each nested ring of the plurality of nested rings being attached to associated movable sections of associated hydraulic cylinders, such that the nested rings are sequentially extended from the recess as the plurality of hydraulic cylinders is extended from the recess, and
a plurality of hydraulic lines attached to and extending between the pump and the hydraulic cylinders, such that each hydraulic cylinder is in fluidic communication with the pump;

a controller attached to the sole and operationally engaged to the actuator, such that the controller is enabled for selectively actuating the actuator for extending the nested rings from the recess, wherein the nested rings are configured for elevating the user from a surface upon which the user is standing or walking, the controller comprising a stem attached to the pump and extending through a sidewall of the sole, wherein the stem is configured for sequentially depressing toward the sidewall for actuating the pump for pumping the hydraulic fluid through the hydraulic lines for extending the nested rings from the recess; and
a panel attached to and extending from a bottom perimeter of the sole, the panel being flexible, such that the panel drapes from the sole to the surface, wherein the panel is configured for shielding the nested rings and the hydraulic cylinders from view by a person proximate to the user, the panel comprising fabric.
