Abstract
At least one of the pair of shoes has a back portion of the shoe, cut from the collar of the back portion (the top of a shoe above the shoe-heel [the heel of the shoe]), and runs down the back of the shoe. The cut forms a slit running down the back portion of the shoe, forming a right-back portion and a left-back portion of the shoe. The right-side edge of the right-back portion and the left-side edge of the left-back portion are separable from the foot being inserted into the shoe. The right-side edge and the left-side edge return back to their positions when the foot is taken off or when the foot is fully inserted, not overlapping each other when the slit is not separated.
