Patent ID: 7810254

Claim:
A shock attenuation system for an insole of a shoe comprising: an insole body, a pressure controller located at a side of said insole body, wherein said pressure controller includes a first multi-pipe circulating flow pressure controller; a second single-pipe bi-directional flow pressure controller; and an adjusting device extending between said first flow pressure controller and said second flow pressure controller, for controlling the operation of said first and second flow pressure controllers, wherein said adjusting device comprises: a rotatable shaft; a rotating knob on a first exterior end of said rotatable shaft; disc-shaped adjusting heads mounted on said rotatable shaft proximate a middle thereof; an adjustable tip at a second interior end of said rotatable shaft whereby, in use, rotation of said rotating knob in one direction rotates the rotatable shaft upwards, thereby closing said first flow pressure controller using said disc-shaped adjusting heads while opening said second flow pressure controller using said adjustable tip; and whereby, in use, rotation of said rotating knob in an opposite direction rotates said rotatable shaft downwards, thereby opening said first flow pressure controller while closing said second flow pressure controller.
