A shoe sole construction which features an outer sole having at least one opening through which a protrusion of a less dense midsole extends. The cutout area of the more dense outsole decreases the overall weight of the sole, while the less dense protrusion aids in cushioning the foot to provide greater comfort and support. Other protrusions may also be provided through other openings in the outsole to further lessen weight and increase the cushioning effect on the foot. Additionally, grooves may be provided on the upper surface of the midsole to increase flexibility of the sole and further aid in cushioning the foot and providing peripheral support where needed. The invention may be applied to athletic shoes, a woman's high-heeled shoe, or other footwear. |
