A knitted component is formed of unitary knit construction and is configured to stretch. The knitted component includes a knit element that includes an auxetic portion configured to move between a first position and a second position as the knitted component stretches. The knitted component also includes a tensile strand formed of unitary knit construction with the knit element. The auxetic portion has an area when in the first position. The tensile strand engages the knit element proximate the auxetic portion. The tensile strand is configured to be manipulated for selectively changing the area of the auxetic portion to vary a stretch characteristic of the knitted component.

1. A knitted component, the knitted component comprising: a knit element that includes an auxetic portion that is configured to move between a first position and a second position as the knitted component stretches; anda tensile strand formed with the knit element;wherein the auxetic portion has an area when in the first position;wherein the tensile strand engages the knit element proximate the auxetic portion;wherein the tensile strand is configured to be manipulated for selectively changing the area of the auxetic portion to vary a stretch characteristic of the knitted component; andwherein the tensile strand is inlaid within one of a course and a wale of the knit element. 2. The knitted component of claim 1, wherein the knit element includes the auxetic portion and an adjacent zone that is proximate the auxetic portion; wherein the auxetic portion includes a border that demarcates the auxetic portion from the adjacent zone;wherein the area of the auxetic portion is defined within the border;wherein the tensile strand engages the knit element proximate the border; andwherein the tensile strand is configured to be manipulated for selectively moving the border to change the area of the auxetic portion. 3. The knitted component of claim 2, wherein the tensile strand is fixed to the knit element proximate the border. 4. The knitted component of claim 2, wherein the tensile strand is engaged with the knit element at a location that is proximate the border; wherein the tensile strand has a longitudinal axis, andwherein the tensile strand is configured to slide along the longitudinal axis of the tensile strand relative to the location and remain engaged with the knit element at the location. 5. The knitted component of claim 2, wherein the border includes a first side and a second side that intersect at a vertex; wherein the first side is configured to rotate relative to the second side about the vertex as the auxetic portion moves between the first position and the second position; andwherein the tensile strand engages the knit element proximate the vertex. 6. The knitted component of claim 5, wherein the vertex is one of a plurality of vertices of the auxetic portion; wherein the tensile strand engages the plurality of vertices; andwherein the tensile strand is configured for selectively moving the plurality of vertices relative to each other for selectively changing the area and to vary the stretch characteristic of the knitted component. 7. The knitted component of claim 2, wherein the auxetic portion has greater elasticity than the adjacent zone. 8. The knitted component of claim 1, wherein the auxetic portion is shaped substantially as a re-entrant triangle. 9. The knitted component of claim 1, wherein the tensile strand includes an exposed segment that is exposed from the knit element; wherein the tensile strand includes an inlaid segment that is inlaid within the knit element;wherein the inlaid segment engages the knit element proximate the auxetic portion; andwherein the exposed segment is configured to be manipulated to selectively change the area of the auxetic portion. 10. The knitted component of claim 9, wherein the tensile strand includes a first end, a second end, and a middle section extending between the first end and second end; wherein the exposed segment includes one of the first end and the second end;wherein the inlaid segment includes the middle section; andwherein the one of the first end and the second end is configured to be manipulated to selectively change the area of the auxetic portion. 11. The knitted component of claim 9, wherein the tensile strand includes a first end, a second end, and a middle section extending between the first end and the second end; wherein the exposed segment includes the middle section; andwherein the middle section is configured to be manipulated to selectively change the area of the auxetic portion. 12. The knitted component of claim 1, further comprising a securement device configured to have a secured position and an unsecured position, wherein, in the secured position, the securement device maintains a set tension in the tensile strand; andwherein, in the unsecured position, the securement device unsecures the tensile strand relative to the knit element to allow for adjustment of the area of the auxetic portion. 13. The knitted component of claim 1, wherein the knitted component defines at least a portion of an upper of an article of footwear. 14. The knitted component of claim 1, wherein the knitted component defines at least a portion of an article of apparel. 15. The knitted component of claim 1, wherein the tensile strand is configured for selectively increasing the area of the auxetic portion when tension in the tensile strand is increased. 16. The knitted component of claim 1, wherein the tensile strand is configured for selectively decreasing the area of the auxetic portion when tension in the tensile strand is increased. 17. An article of footwear comprising: a sole structure; andan upper that is attached to the sole structure, the upper including a stretchable knitted component, the knitted component comprising:a knit element that includes an auxetic portion that is configured to move between a first position and a second position as the knitted component stretches; anda tensile strand formed with the knit element;wherein the auxetic portion has an area when in the first position;wherein the tensile strand engages the auxetic portion;wherein the tensile strand is configured for selectively changing the area of the auxetic portion to vary a stretch characteristic of the knitted component;wherein the tensile strand includes a first end, a second end, and a middle section extending between first end and second end; andwherein at least one segment of the middle section engages an outer boundary of the auxetic portion and is inlaid through the auxetic portion. 18. The article of footwear of claim 17, wherein a second segment of the middle section is exposed from the knit element; andwherein the second segment is configured to be manipulated to selectively change the area of the auxetic portion. 19. The article of footwear of claim 18, further comprising a securement device; wherein the second segment defines a loop that receives the securement device to attach the securement device to the upper;wherein the securement device is configured to move between a first position and a second position;wherein, in the first position, the securement device substantially maintains a first level of tension in the tensile strand to set the area at a first area; andwherein, in the second position, the securement device substantially maintains a second level of tension in the tensile strand to set the area at a second area. 20. The article of footwear of claim 19, wherein the securement device is a shoelace. 21. A knitted component, the knitted component comprising: a knit element that includes an auxetic portion that is configured to move between a first position and a second position as the knitted component stretches, the auxetic portion having a border; anda tensile strand that is inlaid within the knit element;wherein the auxetic portion has an area when in the first position;wherein the tensile strand extends across the auxetic portion and engages a first location and a second location of the border; andwherein the tensile strand is configured for selectively moving the first location relative to the second location to change the area of the auxetic portion to vary a stretch characteristic of the knitted component. 22.
