Abstract
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.
