Abstract
Footwear with enhanced wearing comfortability, stability and orthotic foot support are disclosed. The footwear comprises built-in intrinsic midsole, anatomically shaped footbed having a functional arch concavity on a medial side, and deep heel cup. The built-in intrinsic midsole provides ideal foot support and function. Raised sidewalls accentuate a deep heel cup, which controls and matches the natural anatomic shape of the foot. The midsole is made by direct single density injection with integrated orthotic contour. The direct injection midsole to upper creates a strong bond, and resolves a potential of delaminating soles. Furthermore, it eliminates the need and cost of cementing, and improves instant fit/comfort.
