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. The midsole includes a top surface having a toe portion with an end-of-toe region, and the midsole defines at least one discrete channel having an inner end and an outer end connected to an orifice on an exterior side surface of the midsole. The inner end of the channel is closer to the end-of-toe region of the midsole than is the outer end of the channel, and water entering the first drainage canal from the top surface of the insole will enter the groove in the bottom surface of the insole, drain into the channel in the midsole, and exit the channel drainage component through the orifice on the exterior side surface of the channel drainage component. |
