A foot arch support device includes a base seat, a movable unit, high and low heel members, and an actuating unit. The base seat includes a first base plate. The movable unit includes a movable plate that is movable relative to the first base plate between high and low curvature positions. When the low heel member is coupled to the base seat, the movable plate is at the low curvature position. When the high heel member is coupled to the base seat, a support part of the high heel member abuts against the movable plate, and the movable plate is pushed by the high heel member to the high curvature position. The actuating unit is operable for permitting removal of a selected one of the high and low heel members from the base seat.

A high-heeled shoe having a sole and a heel of at least 4 cm height provided thereto, wherein the heel is provided with a damping element. The damping element has different effective damping cross sections along the heel's longitudinal axis and/or is freely deformable in at least one direction perpendicular to the heel's longitudinal axis.

A shoe and an outsole therefor. The shoe has a high heel and upper body. The shoe outsole engages the upper body and includes an inside surface and an outside surface opposite the inside surface. The outside surface has a posterior portion, an anterior portion continuous with the posterior portion and an integral raised platform formed on the anterior portion. The integral raised platform includes an etched pattern on a surface thereof, while the inside surface includes a textured portion. The shoe includes at least one side edge, and the integral raised platform is disposed a first distance therefrom. The integral raised platform has a first height of 4.0 mm, and tapers to a second height proximate a toe edge of the shoe, the second height being less than the first height. Insoles for the shoe are also disclosed.
