Official abstract text for this publication.
A rapid-entry shoe having a heel counter to prevent inward deflection of a rear portion of the upper, but the heel counter having a vertical slit to permit downward deflection of the rear portion of the upper, so as to expand a perimeter of an opening of the shoe to receive a foot and thereby facilitate donning and doffing of the rapid-entry shoe.
Opening claim text (preview).
We claim: 1. A rapid-entry shoe comprising: a sole portion; an upper having a rear portion coupled to the sole portion and extending around a heel of the rapid-entry shoe; and a heel counter extending between opposing sides of the shoe around the heel and coupled to an outer surface of the upper; wherein the heel counter comprises a vertical slit configured to permit downward deflection of the rear portion of the upper; wherein the rapid-entry shoe has an uncollapsed configuration; wherein the rapid-entry shoe has a collapsed configuration to facilitate donning and doffing of the rapid-entry shoe; wherein, in the uncollapsed configuration, the vertical slit is substantially closed; wherein, in the collapsed configuration, the vertical slit is open to create an aperture through the heel counter open to the rear portion and expand a perimeter of the heel counter; wherein the rapid-entry shoe is biased by the heel counter toward the uncollapsed configuration; wherein, in the collapsed configuration, a bowed portion of the heel counter is folded over a lower portion of the heel counter; wherein in the collapsed configuration opposing ends of the vertical slit are moved toward one another and lateral edges of the vertical slit are moved away from one another; and wherein the slit remains closed to a topline of the upper in both the uncollapsed configuration and the collapsed configuration. 2. The rapid-entry shoe of claim 1 , further comprising an enlarged portion positioned at a first end of the vertical slit. 3. The rapid-entry shoe of claim 2 , wherein the enlarged portion has a circular shape. 4. The rapid-entry shoe of claim 1 , further comprising a horizontal slit that intersects the vertical slit. 5. The rapid-entry shoe of claim 1 , further comprising a stitch provided at a first end of the vertical slit. 6. The rapid-entry shoe of claim 1 , further comprising a stabilizer coupled to a rear portion of the upper. 7. The rapid-entry shoe of claim 1 , wherein lateral edges of the vertical slit are bowed outward when the rapid-entry shoe moves toward the collapsed configuration. 8. A heel counter for a shoe, comprising: at least one slit extending between a first location on the heel counter and a second location on the heel counter, the first location being removed from a first edge of the heel counter and the second location being removed from a second edge of the heel counter and wherein: the slit is biased toward a closed position in which the slit is substantially closed; and the slit moves toward an open position in response to deformation of the heel counter and wherein movement toward the open position causes the slit to define an aperture and further wherein a bowed portion of the heel counter is folded over a lower portion of the heel counter when the slit is in the open position. 9. The heel counter of claim 8 , further comprising a cover associated with the aperture.
