Abstract: In accordance with an aspect of the invention, a footwear comprises a base and a retainer being coupled to the base for forming a cavity and an opening thereto. The footwear further comprises a heel counter being coupled to at least one of the base and the retainer. The heel counter is biased in an up position and is positionable between the up position and a down position. When a foot interacts with the heel counter, the heel counter is positioned away from the up position towards the down position for facilitating access of a foot to the opening. Subsequently, when the foot is fully inserted into the cavity, the heel counter returns to the up position for engaging the heel of the foot in order for preventing dislodgement of the foot from the cavity.
