Abstract
A ventilation system for an article of footwear including a ventilated midsole and a ventilated wing for routing warm/moist air from around a wearer's foot to at least one vent in the upper. The ventilated midsole and wings may be integrally formed from a sheet of ventilated material. Alternatively, the ventilated midsole and the ventilated wing are separately formed and fitted together within the article of footwear. When formed separately, the ventilated midsole may be molded with a cavity in the bottom surface to receive the wing. The wing may include a first portion disposed in the cavity and a second portion providing a flow path to the vent. The ventilation system may be used with a waterproof/breathable bootie. The ventilation system may be positioned inside or outside the bootie. The tongue may also include a tongue ventilation system with a tongue ventilation insert and a tongue vent.
