ABSTRACT:
A sole for hiking boots is provided as an article of manufacture. The sole has a top surface and also a bottom tread surface which, intermediate the ends of the sole, is disposed in a sole base plane. At its rear end, the sole has a distinct substantially straight extent generally perpendicular to the length of the sole so that, when the sole is viewed in a direction substantially normal to the top surface, it has a substantially square heel. Adjacent the front and rear ends of the sole, the tread surface is cylindrically curved concave upwardly away from the base plane proceeding toward the adjacent ends of the sole. The directrix of each of these cylinders is substantially parallel to the sole base plane and substantially perpendicular to the length of the sole.
