Abstract

The heel counter structure includes a sole plate provided at least at the heel region of the shoe and having a peripheral portion. The peripheral portion is upraised along the heel region of the shoe so as to enclose the lower portion of the heel portion of the foot of the wearer. The heel structure also includes a pair of heel counter portions provided on the medial and lateral sides of the heel region of the shoe so as to sandwich the heel portion of the foot sideways. The heel counter portions are coupled to the peripheral portion of the sole plate at the lower ends of the heel counter portions so that the heel counter portions can tilt inwardly and outwardly independently of the sole plate. The heel counter portions are separated from the peripheral portion of the sole plate except the lower ends of the heel counter portions.
