Abstract
An insert for a shoe, boot, or the like which is capable of plural adjustments so as to adapt the insert to the unique physical conformation of the wearer's foot, to hold the foot in a neutral axis position substantially at all times, to return a foot into the neutral axis mode automatically, and to provide a wide range of support, resiliency, and angulation based on the needs of the user. The device as set forth lends itself to modification for various sports where lateral motion is of primary importance, shock absorption and longitudinal extension of the foot is of paramount importance, or for geriatric patients whereby a single insert and the modifying devices associated therewith address the vast spectrum of orthotic needs.

An orthotic appliance adapted to be placed as an insert within or form a part of a boot, shoe, or the like comprising in combination:
- an initial blank having an upper surface that generally follows the contour of the plantar surface of a foot,
- a bottom surface of said blank having a zone of disparate resiliency relative to areas adjacent said zone,
- cap means underlying said bottom surface,
- and means for interfitting said cap to said blank wherein said interfitting means comprises a peripheral wall extending up from said cap engaging side walls of said blank, said side walls including a stepped in shelf portion complemental to the thickness of said perpheral wall so that the outer side edges of said appliance is substantially smooth.
