Abstract:
An improved insole to be adapted to underlie the anatomical structure of the wearer's foot, the foot having a lateral longitudinal arch, a medial longitudinal arch and a longitudinal border there between, 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 there between, wherein the improvement comprises:at least one but no more than six transversely spaced flow deflectors in the proximal forefoot region of said bladder, said deflectors being spaced apart relative to one another;at least two, 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;a transverse wall in the proximal end of the proximal forefoot region, said transverse wall extending transversely from the lateral and medial peripheral margins, and having at least one opening therein to allow fluid to flow from the proximal forefoot region to the midfoot region of said bladder;an elongated flow controller bridging the forefoot and midfoot regions of said bladder, the elongation of said flow controller substantially matching at least a portion of said longitudinal border between the medial longitudinal arch and the lateral longitudinal arch of the wearer's foot,said fluid comprising a heavy viscous liquid.
