Claims16
An adjustable foot support system for use in a shoe, having a toe portion, a heel portion, and a mid-portion therebetween, comprising (i) a footbed assembly which has a longitudinal center, a flat bottom surface and an upper surface which has raised peripheral edges at the mid-portion that slope gradually downward from each edge toward the longitudinal center of the foot-bed assembly so as to form a concave shaped surface facing upward at about the mid-portion;
- (ii) a shim member having a toe portion, a heel portion, and a mid-portion therebetween which has a hinge, and having a flat upper surface and a lower surface which has a transversely convex contour at about the mid-portion of the shim facing downward, thereby matching and fitting together with the footbed assembly located therebelow, and having the shim mid-portion being narrower than the corresponding footbed assembly mid-portion location, and (iii) a means for moving the shim member transversely to adjust the angle of the flat upper surface of the shim member relative to the flat bottom surface of the footbed assembly.
A shoe comprising a shoe upper, a shoe bottom, and an adjustable foot support system in the shoe, said support system comprising a footbed assembly having a longitudinal center, a toe portion, a heel portion, and a mid-portion therebetween, and having a flat bottom surface and an upper surface which has raised peripheral edges at the mid-portion that slope gradually downward from each edge toward the longitudinal center of the footbed assembly so as to form a concave shaped surface facing upward at the mid-portion;
- (ii) a shim member having a toe portion, a heel portion, and a mid-portion therebetween which has a hinge, and having a flat upper surface and a lower surface which has a transversely convex contour at about the mid-portion of the shim facing downward, thereby matching and fitting together with the footbed assembly located therebelow, and having the shim mid-portion being narrower than the corresponding footbed assembly mid-portion location, and (iii) a means for moving the shim member transversely from side to side, there-by adjusting the angle of the flat upper surface of the shim member relative to the flat bottom surface of the footbed assembly.
