4. An interior member according to claim 3 , wherein the tongue portion is a formed as a separate member from the first material element, and the third seam and the fourth seam extend around at least a portion of a front edge of the first material element and connect the front edge of the first material element to at least a portion of a front edge of the tongue portion.
5. An interior member according to claim 1 , wherein the first material element includes a non-porous layer and an impact-attenuating layer.
6. An interior member according to claim 1 , wherein the first material element forms a double layer at a lateral ankle edge portion of the foot-receiving chamber.
7. An interior member according to claim 1 , wherein the first material element forms a double layer at a medial ankle edge portion of the foot-receiving chamber.
8. An interior member according to claim 1 , wherein the first material element forms a double layer at a lateral ankle edge portion, at a medial ankle edge portion, and along an Achilles portion of the foot-receiving chamber.
9. An interior member according to claim 1 , wherein the first material element extends from the heel-surrounding portion to provide an ankle-containing portion.
10. An interior member according to claim 1 , wherein a first seam joins a lateral edge of the heel-surrounding portion with a first lateral edge of the lateral side portion, and wherein a second seam joins a medial edge of the heel-surrounding portion with a first medial edge of the medial side portion.
11. A foot-receiving device, comprising:
a bootie element defining a foot-receiving chamber, the bootie element including,
a first material element having a plantar portion forming a bottom surface of the bootie element, the first material element having a length defined in a toe to a heel direction and a width defined in a medial to a lateral direction,
a heel-surrounding portion seamlessly connected to the plantar portion and extending-upward from a rear end of the plantar portion,
a lateral side portion seamlessly connected to the plantar portion and extending upward from a lateral side of the plantar portion,
a medial side portion seamlessly connected to the plantar portion and extending upward from a medial side of the plantar portion, and
an Achilles portion that forms a double layer along an Achilles region of the foot-receiving chamber, the Achilles portion being elongated and having a width measured in the medial to the lateral direction that is smaller than a width of the heel-surrounding portion measured in the medial to the lateral direction;
the first material element includes the plantar portion, the heel-surrounding portion, the lateral side portion, and the medial side portion in a continuous, one-piece arrangement, wherein the plantar portion is seamless, such that the bottom surface of the bootie element has no seams thereon;
the first material element forms a double layer at a lateral ankle edge portion of the foot-receiving chamber; and
a first foot-receiving device component engaged with the bootie element.
12. A foot-receiving device according to claim 11 , wherein the first foot-receiving device component includes at least a portion of a sole member for an article of footwear, the sole member positioned beneath the bottom surface of the bootie element.
13. A foot-receiving device according to claim 11 , wherein the first foot-receiving device component includes at least a portion of a midsole member for an article of footwear, the midsole member positioned beneath the bottom surface of the bootie element.
14. A foot-receiving device according to claim 11 , wherein the first foot-receiving device component includes at least a portion of an upper member for an article of footwear, the upper member being-positioned around at least a portion of the heel-surrounding-portion, the medial side portion, and the lateral side portion of the bootie element.
