Abstract
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 metatarsal pad in the proximal forefoot region of the bladder; flow passages between the metatarsal pad and the medial and lateral and peripheral margins of the bladder; a flow controller bridging the proximal forefoot and midfoot regions of the bladder and matched to the border between the lateral and medial longitudinal arch; and flow restrictors in the distal hindfoot defining a central longitudinal flow channel between the hindfoot and midfoot regions. The metatarsal pads and fluid flow are matched to the anatomical structure of the foot.
Claims9
An insole, comprising
- a substantially fluid tight bladder, said bladder comprising an upper layer and a lower layer sealing joined at their peripheral margins, said bladder having a generally foot shaped planar configuration with a proximal forefoot region, a hindfoot region and an midfoot region there between,
- a heavy liquid substantially filling said bladder;
- at least two transversely spaced metatarsal pads between said upper and lower bladder layers in said proximal forefoot region of said bladder, said pads comprising a solid or semi-solid material;
- and
- at least one substantially longitudinal, forefoot flow passage between said pads in said proximal forefoot region,
- at least two substantially longitudinal forefoot flow passages between said pads and the medial margin of said proximal forefoot region of said bladder and between said pads and the lateral margin of said forefoot region of said bladder, said liquid being flowable through at least one of said forefoot flow passages in a longitudinal direction within the proximal forefoot region and from the proximal forefoot region into the midfoot region of said bladder.
