a center segment;
a medial side arm extending from the center segment to a medial end connected to a medial side of the base; and
a lateral side arm extending from the center segment to a lateral end connected to a lateral side of the base; wherein the center segments of the plurality of slats progressively increase in width from the lowermost slat to the uppermost slat, with the center segment of the at least one of the intermediate slat being wider than the center segment of the lowermost slat, and the center segment of the uppermost slat being wider than the center segment of the at least one intermediate slat; and
wherein the control bar is resiliently bendable between an unloaded position and a loaded position in which at least one center segment is closer to the base than in the unloaded position.
2. The device of claim 1 , wherein the medial side arms of the plurality of slats progressively increase in width from the lowermost slat to the uppermost slat.
3. The device of claim 1 , wherein the lateral side arms of the plurality of slats progressively increase in width from the lowermost slat to the uppermost slat.
4. The device of claim 1 , wherein:
the center segment of the uppermost slat has an elongated tip; and
an upper surface of the elongated tip has a slope that increases in a forward and downward direction.
5. The device of claim 1 , further comprising:
a peg extending from the center segment of one of the plurality of slats in a direction away from the medial side arm and the lateral side arm.
6. The device of claim 5 , wherein the peg extends from the lowermost slat.
7. The device of claim 5 , wherein the peg extends outward from a thickened region of the center segment.
8. The device of claim 5 , wherein the peg is a first peg, and further comprising:
a second peg extending outward from a rear of the base.
9. The device of claim 8 , further comprising:
a third peg extending from a medial side of the base; and
a fourth peg extending from a lateral side of the base.
10. The device of claim 1 , wherein:
the base includes a relatively thick portion adjacent an uppermost extent of the base and a relatively thin portion adjacent a lowermost extent of the base; and
the relatively thin portion has a greater height at a center of a rear of the base than the relatively thick portion.
11. The device of claim 10 , wherein the relatively thick portion has a greater height at medial and lateral sides of the base than the relatively thin portion.
12. An article of footwear comprising:
an upper defining a foot-receiving cavity with a heel region, the upper having a heel collar defining an opening into the foot-receiving cavity;
wherein the upper includes and inner layer and an outer layer, the inner layer and the outer layer defining an internal cavity; and
a heel support device extending around a rear of a heel region and including a control bar and a base, wherein both the control bar and the base are in the internal cavity;
wherein the control bar includes a plurality of slats, the plurality of slats including an uppermost slat, a lowermost slat closer to the base than the uppermost slat, and at least one intermediate slat disposed between the uppermost slat and the lowermost slat; each slat of the plurality of slats having:
a center segment;
a medial side arm extending from the center segment to a medial end connected to a medial side of the base; and
a lateral side arm extending from the center segment to a lateral end connected to a lateral side of the base;
wherein;
the control bar is resiliently bendable between an unloaded position and a loaded position in which at least one center segment is closer to the base than in the unloaded position;
the center segments of the plurality of slats progressively increase in width from the lowermost slat to the uppermost slat;
the base includes a relatively thick portion adjacent an uppermost extent of the base and a relatively thin portion adjacent a lowermost extent of the base; and
the upper is sewn or adhered to the relatively thin portion of the base.
13. The article of footwear of claim 12 , wherein the center segment of one slat of the plurality of slats includes an elongated tip extending rearwardly.
14. The article of footwear of claim 13 , wherein:
the upper has a tapered extension extending rearward from the heel collar;
the center segment of the uppermost slat has the elongated tip; and
the elongated tip is disposed in the internal cavity at the tapered extension of the heel collar.
15. The article of footwear of claim 14 , wherein an upper surface of the elongated tip slopes downward and inward toward the foot-receiving cavity.
16. The article of footwear of claim 12 , wherein the heel support device includes a peg extending through an aperture in the upper and secured at a surface of the upper.
17. A device for easing foot entry into an article of footwear, the device comprising:
a control bar and a base underlying the control bar;
wherein the control bar includes a plurality of slats, the plurality of slats including an uppermost slat, a lowermost slat closer to the base than the uppermost slat, and at least one intermediate slat disposed between the uppermost slat and the lowermost slat; each slat of the plurality of slats having:
a center segment;
a medial side arm extending from the center segment to a medial end connected to a medial side of the base; and
a lateral side arm extending from the center segment to a lateral end connected to a lateral side of the base; wherein the center segments of the plurality of slats progressively increase in width from the lowermost slat to the uppermost slat; and
wherein:
the control bar is resiliently bendable between an unloaded position and a loaded position in which at least one center segment is closer to the base than in the unloaded position;
the base includes a relatively thick portion adjacent an uppermost extent of the base and a relatively thin portion adjacent a lowermost extent of the base; and
the relatively thin portion has a greater height at a center of a rear of the base than the relatively thick portion.
