ABSTRACT:
An insole comprising a bladder which is filled with a water and air, and having a metatarsal and heel area for cushioning the foot of the user. Flow restrictions are located between the metatarsal and heel area of the bladder so as to restrict the flow of water and air from the metatarsal area to the heel area and vice versa. The flow restrictions are C-shaped seals in the bladder and provide a massaging action for the foot of the user.
