Abstract
Abstract A hiking or military boot or shoe is provided with a sole formed with a plurality of internal passages which lighten the sole, enhance the flexibility of the sole and provide a portion of a shoe ventilation system. Included is a snorkel arrangement connected to the internal passages to ventilate the sole, with the outlet therefor at an elevated level to prevent moisture from entering the shoe. Preferably, the footwear is comprised of a moisture and air impervious material.
