Embodiments of the present invention relate to the construction of a shoe that is comprised of a disengageable-heel portion that may be disengaged from an upper. Disengagement of the heel portion from the upper allows the heel portion to fold away from the upper, which exposes a heel-end opening that a foot may pass through to gain entry to the interior of the shoe. Additionally, a stretchable lacing material may be utilized to allow the shoe to absorb energy exerted on to it by a wearer of the shoe without disengaging the heel portion from the upper.

The object of the invention is an elastic shoelace with an eye and a ring. The elastic shoelace of the invention can easily be passed through holes (B) in a shoe (A) and by increasing or decreasing the tightening of an elastic string (1) a ring (5) is hooked onto a threaded pin (4) thus achieving favourable shoe tying.

In the conventional lace with knobby portions having elastic rubber core, there is difference in degree of stretch between both ends and core of the knobby portion. Therefore, there are a portion that is subjected to heavy stretching force and a portion that is subjected to no stretching force, and when large strain is accumulated at the boundary between the portions subjected to different stretching forces and the strain reaches the limit, the lace ruptures. In order to solve the above problem, we provide a lace provided with tubular lace body of elastic material, comprising knobby portions repeatedly placed at intervals, of which diameter vary depending on tension on the knobby portion in an axial direction.
