A sole core formed in the shape of a strip is disposed longitudinally along a central portion of the sole and functions as an axis of rotation with torsional flexibility. More specifically, in one embodiment of the present invention, a sole for a snowboard boot includes a middle sole core member extending with the sole along a longitudinal center core line (T), wherein a left edge the middle sole core member is spaced apart from a left lateral edge of the sole, and wherein a right edge of the middle sole core member is spaced apart from a right lateral edge of the sole. If desired, the center core line (T) may be inclined relative to the longitudinal centerline of the boot. Separate or connected left and right sole core members may be formed on the left and right sides of the middle sole core member, respectively.
