ABSTRACT:
A fluid filled insole wherein the flow of fluid is matched to the anatomical structure of functionally normal feet comprises a fluid tight bladder having upper and lower layers and a generally foot-shaped, planar configuration, with proximal forefoot, midfoot and hindfoot regions; a heavy, viscous, sterile liquid substantially filling the bladder; at least one, preferably between two and six transversely spaced forefoot flow deflectors joining the upper and lower layers in the proximal forefoot region of the bladder; flow passages matched to the anatomical structure of the foot between the forefoot flow deflectors and the medial and lateral and peripheral margins of the bladder; and two transverse walls, one in the proximal end of said proximal forefoot region and the other in the distal end of the hindfoot region, each transverse wall having an opening forming a longitudinal passageway. Alternatively, the walls may be viewed as two pairs of flow restrictors; one pair of restrictors in the proximal end of the proximal forefoot region and the other pair in the distal end of the hindfoot region, each pair of restrictors defining a longitudinal flow channel there between. Also included is an elongated flow restrictor in the arch region. A second embodiment has two elongated flow controllers extending from the proximal forefoot region to the distal hindfoot region, the controllers substantially underlying the medial and lateral longitudinal arches.
