Abstract: Embodiments of the present invention relate to a construction of a shoe that includes a tongue that has a first fastener attached along a portion of either a medial side or a lateral side of the tongue. Additionally, a stretchable member is attached near a portion of the medial side or the lateral side of the tongue that is opposite of the first fastener. The first fastener is attachable to the upper near the location of the first fastener on the tongue. Similarly, the stretchable member is attached to the upper near the location of the stretchable member on the tongue.

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.
