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. |
