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 two but no more than six transversely spaced forefoot flow deflectors joining the upper and lower layers in the proximal forefoot region of the bladder; at least one but no more than five transversely spaced hindfoot flow deflectors joining the upper and lower layers in the hindfoot region of the bladder; flow passages matched to the anatomical structure of the foot between the forefoot and hindfoot flow deflectors and the medial and lateral and peripheral margins of the bladder; a flow controller matched to the border between the lateral and medial longitudinal arch, whereby liquid flows from the hindfoot region to the forefoot region and vice versa. The flow through the insole passages and channels matches the anatomical structure of the foot; disperses the user's weight evenly over the area of the foot, thereby reducing peak pressures on the plantar surfaces of the user's foot; provides directional stability when using the insole for walking, running or standing; improves the venous pump function with resulting medical benefits; and ensures an accumulation of liquid under the medial arch of the user's foot to form a liquid pillow that matches the anatomical structure of the medial longitudinal arch.

[ What is claimed is:] [1.] An improved insole adapted to be worn beneath the wearer's foot, said insole of the type in which a bladder is filled with a fluid, said bladder having a generally foot-shaped configuration with a proximal forefoot region, a hindfoot region and a midfoot region therebetween, wherein the improvement comprises:at least two but no more than six transversely spaced flow deflectors in the proximal forefoot region of said bladder, said deflectors being equally spaced apart relative to one another;at least three, but no more than seven forefoot flow passages between each of said flow deflectors and between said flow deflectors and the lateral and medial margins of the proximal forefoot region of said bladder, said forefoot flow passages having substantially equal transverse dimension, and at least one of said forefoot flow passages extending between the proximal forefoot region and the midfoot region of said bladder;at least one but not more than five transversely spaced flow deflectors in the hindfoot region of said bladder;at least one but not more than six flow passages between said hindfoot flow deflectors and between said hindfoot flow deflectors and the lateral and medial margins of said bladder, said hindfoot flow passages having substantially equal transverse dimension, and at least one of said hindfoot flow passages extending from the hindfoot region into the midfoot region of said bladder;a pair of flow restrictors at the distal end of the hindfoot region of said bladder, one of said restrictors adjacent the medial peripheral margin of said bladder and the other adjacent the lateral peripheral margin of said bladder, said pair of restrictors defining a longitudinal flow channel therebetween; andsaid fluid comprising a heavy, viscous liquid.
