  • Article of footwear with channel drainage system
    Publication number: 20010025432
    Abstract: An insole for use in constructing a channel drainage component includes a top surface and a bottom surface, and the insole defines a first drainage canal that runs through the insole from the top surface of the insole to the bottom surface of the insole. The bottom surface of the insole defines a first drainage network that includes a first groove that spirals outward from a first central region in the bottom surface of the insole. The first drainage canal runs from the top surface of the insole into the at least first groove of the first drainage network. A channel drainage component includes an insole and a midsole. The insole has a top surface and a bottom surface and defines a first drainage canal running from the top surface to the bottom surface. The bottom surface of the insole defines a first drainage network that includes a first groove, and the first drainage canal runs from the top surface of the insole into the first groove of the first drainage network defined in the bottom surface of the insole.
