A fluid filled insole 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 a flow controller matched to the border between the lateral and medial longitudinal arch. The hindfoot region of the bladder may comprise, alternatively (1) at least one hindfoot flow deflector, (2) flow restrictors in the distal hindfoot defining a central longitudinal flow channel between the hindfoot and midfoot regions, or (3) a barrier between the midfoot and hindfoot regions, and the hindfoot region comprising at least in part of a shock absorbing material. The flow of fluid within the insole is thereby matched to the anatomical structure of functionally normal feet.
