Title: Adjustable semi-flexible health shoe

Abstract: An adjustable semi-flexible shoe is disclosed which is structurally and isometrically adapted for controllably stably supporting a human foot during walking following surgical and therapeutical treatment of the user's lower extremities while simultaneously permitting an approximated natural gait. A laminated elongate sole of semi-flexible polymeric materials has an upper sole laminate which stably supports the foot substantially free of compression while permitting limited longitudinal flexing and a lower outer sole laminate with a substantially flat surface extending from the metatarsal area through the heel area and an upwardly tapered surface in the toe area which affords cushioned approximated natural ambulation. A single integral canvas upper has a lower portion extending transversely through the sole and upper flaps which are adjustably releasably connected with one another to adjustably stably secure the user's foot to the sole.
