Abstract

Footwear, including athletic footwear, opens very wide, e.g., by moving an ankle containing portion of a footwear upper laterally/sideways with respect to the sole structure or a base portion of the upper (e.g., rotate it to the lateral side). In effect, the ankle containing portion may move/rotate sideways with respect to the sole structure/base portion via a connecting member (e.g., moving akin to rotation on a hinge type structure) to open in somewhat of a “clamshell” fashion. The rear of the upper base portion in this open condition may appear somewhat as an open backed slipper or “slide” type shoe. These actions and features open the rear heel area of the upper wide and low to enable easy insertion of a foot into the interior chamber, generally from the rear of the footwear structure. One or more straps can be used to secure the upper to the foot.

First claim

What is claimed is:

1. An article of footwear, comprising:
an upper including a top opening, a first side, a second side, a first side edge extending downward from the top opening at the first side, and a second side edge extending downward from the top opening at the second side, wherein the second side edge includes a downward extending segment and a rearward extending segment, and wherein the upper further includes a foot insertion opening extending from the first side edge and terminating at a closed end located at a side heel area of the upper on the second side of the upper;
a closure system engaged with the upper for releasably closing the foot insertion opening, wherein the closure system extends between the closed end and the first side edge of the upper; and
a sole structure engaged with the upper.

2. An article of footwear according to claim 1 , further comprising a securing strap engaged with the upper and extending across a top forefoot portion of the upper or a top midfoot portion of the upper one or more times.

3. An article of footwear according to claim 1 , wherein the rearward extending segment of the second side edge terminates at a closed end, wherein the closed end of the second side edge is located a distance L from the closed end of the closure system, wherein L is within a range of from 10 mm to 70 mm.

4. An article of footwear according to claim 1 , wherein the closure system includes a track extending along the second side of the upper, wherein an end portion of the track along the second side of the upper substantially aligns with an extension direction of the rearward extending segment of the second side edge of the upper.

5. An article of footwear according to claim 1 , wherein the rearward extending segment of the second side edge terminates at a closed end, wherein the upper further includes a connecting member extending between the closed end of the foot insertion opening and the closed end of the rearward extending segment of the second side edge, and wherein an ankle containing portion of the upper is movable with respect to a base portion of the upper about the connecting member to change the upper from a foot insertion configuration to a foot engaging configuration.

6. An article of footwear according to claim 5 , wherein a length dimension from a first side of the connecting member to a second side of the connecting member is within a range of from 10 mm to 70 mm.

7. An article of footwear according to claim 1 , wherein the closure system includes a track extending along the foot insertion opening and a closure element movable along track, wherein the closure element changes the foot insertion opening between an open condition and a closed condition.

8. An article of footwear, comprising:
an upper including a top opening, a first side, a second side, a first side edge extending downward from the top opening at the first side, and a second side edge extending downward from the top opening at the second side, wherein the upper further includes a foot insertion opening extending from the first side edge and terminating at a closed end located at a side heel area of the upper on the second side of the upper;
a closure system engaged with the upper for releasably closing the foot insertion opening, wherein the closure system extends between the closed end and the first side edge of the upper, wherein the closure system includes a track extending along the foot insertion opening and a closure element movable along track, wherein the closure element changes the foot insertion opening between an open condition and a closed condition;
an ankle strap secured to the closure element, wherein the second side of the upper has a securing member, wherein in the closed condition:
the closure element stops along the track at the first side edge of the upper;
the ankle strap extends around a front instep or front ankle portion of the upper and is secured to the securing member at the second side of the upper; and
with the sole structure supported on a horizontal support surface, the ankle strap extends to a location on the second side of the upper that is more rearward than a location of the closed end of the foot insertion opening; and

a sole structure engaged with the upper.

9. An article of footwear, comprising:
an upper including a top opening, a first side, a second side, a first side edge extending downward from the top opening at the first side, and a second side edge extending downward from the top opening at the second side, wherein the upper further includes a foot insertion opening extending from the first side edge and terminating at a closed end located at a side heel area of the upper on the second side of the upper;
a closure system engaged with the upper for releasably closing the foot insertion opening, wherein the closure system extends between the closed end and the first side edge of the upper, wherein the closure system includes a track extending along the foot insertion opening and a closure element movable along track, wherein the closure element changes the foot insertion opening between an open condition and a closed condition; and
a sole structure engaged with the upper, wherein with the sole structure supported on a horizontal support surface, the track includes a first side portion, a rear heel portion, and a second side portion, wherein a vertically lowest section of the track is located in the rear heel portion, wherein the track extends to the first side portion in an upward direction forward from the vertically lowest section, and wherein the track extends to the second side portion in an upward direction forward from the vertically lowest section.

10. An article of footwear according to claim 1 , further comprising:
a first strap engaging component including a first tensioning device provided at a midfoot portion on the second side of the upper;
a second strap engaging component provided at a midfoot portion on the first side of the upper; and
a securing strap extending across a top forefoot portion of the upper, wherein the securing strap includes a first portion fixed at a forefoot portion on the first side of the upper and a flexible strap portion extending from the first portion, to the first tensioning device, and to the second strap engaging component.

11. An article of footwear, comprising:
a sole structure;
an upper engaged with the sole structure, wherein the upper, at least in part, defines a foot-receiving volume configured to receive a wearer's foot in use, the upper including:
(a) an ankle containing portion including a first side, a rear heel area, and a second side,
(b) a base portion including a first side and a second side, and
(c) a connecting member connecting the second side of the ankle containing portion and the second side of the base portion,

wherein, with the sole structure supported on a horizontal support surface, the upper is changeable by movement of the ankle containing portion with respect to the base portion at the connecting member between: (a) a foot engaging configuration in which the first side of the ankle containing portion of the upper is positioned over the first side of the base portion to close the upper and (b) a foot insertion configuration in which the first side of the ankle containing portion of the upper is positioned sideways outside of the second side of the base portion with respect to the foot-receiving volume of the upper to open a rear heel area of the upper;
a closure system for releasably holding the upper in the foot engaging configuration wherein the closure system engages at least a section of a lower edge of the ankle containing portion with at least a section of an
