Abstract

A footbed having the ability to fixedly secure the forefoot portion of the foot while allowing the heel portion to laterally move during activity is provided. The footbed can include a sock liner positioned thereon wherein the sock liner is more firmly secured to the footbed in the forefront region than in the heel region to allow lateral movement.

First claim

1 . A footbed for an article of footwear, the footbed comprising:
a sole structure including a lower ground engaging surface and an upper foot facing surface, the sole structure having a forefoot region and a rear foot region; a foot engaging member including a lower surface facing the sole structure foot facing surface and an upper surface adapted to face and engage the foot of the wearer, the foot engaging member having at least a rear foot region; and wherein the foot engaging member rear foot region is capable of lateral movement with respect to the sole structure rear foot region.

2 . The footbed of claim 1 , wherein the foot engaging member includes a forefoot region and wherein the foot engaging member forefoot region is relatively fixed with respect to the sole structure forefoot region.

3 . The footbed of claim 1 , wherein the foot engaging member is a sock liner.

4 . The footbed of claim 1 , further including a low friction area positioned on the lower surface of the foot engaging member in the rear foot region of the foot engaging member, wherein the low friction area has a lesser coefficient of friction in relation to the sole structure foot facing surface than an area of the lower surface of the foot engaging member in the forefoot region of the foot engaging member.

5 . The footbed of claim 1 , further including a low friction area positioned on the upper surface of the sole structure in the rear foot region of the sole structure.

6 . The footbed of claim 1 , further comprising:
a first low friction area positioned on the lower surface of the foot engaging member in the rear foot region of the foot engaging member; a second low friction area positioned on the upper surface of the sole structure in the rear foot region of the sole structure: and wherein the first low friction area engages the second low friction area to allow the lateral movement of the foot engaging member.

7 . The footbed of claim 4 wherein the low friction area is made of a synthetic suede.

8 . The footbed of claim 5 wherein the low friction area is made of a lubricious fluoropolymer material.

9 . The footbed of claim 1 wherein the foot engaging member upper surface is made of a highly compressible foam so as to be capable of conforming to the wearer's foot.

10 . The footbed of claim 2 wherein the forefoot region of the foot engaging member is secured to the forefoot region of the sole structure by an adhesive.

11 . The footbed of claim 2 wherein relative movement of the forefoot region of the foot engaging member is prevented with respect to the forefoot region of the sole structure by providing a high coefficient of friction between the respective forefoot regions.

12 . A shoe construction comprising:
a sole structure including a forefoot region, a midfoot region and a rear foot region; an upper secured to the sole structure and capable of encasing the foot of the wearer and including a forefoot region, a midfoot region, and a rear foot region; an insole positioned between the sole structure and a foot of a wearer, the insole including a forefoot region, a midfoot region and a rear region; a sock liner positioned within the upper and on a top surface of the insole, the sock liner including a forefoot region, a midfoot region in a rear foot region; the sock liner including a first low friction area in the sock liner rear foot region; and wherein the sock liner is relatively locationally fixed to the forefoot region of the insole and the first low friction area of the sock liner engages the rear foot region of the insole so as to allow movement of the rear foot region of the sock liner in the lateral and medial directions.

13 . This shoe construction of claim 12 , including a second low friction area positioned in the rear foot area of the insole and engaging the first low friction area.

14 . The shoe construction of claim 12 , wherein the forefoot area of the insole is relatively fixed to the forefoot region of the sock liner through the provision of a high coefficient of friction.

15 . A sock liner for an article of footwear comprising:
a first longitudinal layer including a toe region, a midfoot region and a heel region, the first longitudinal layer having an upper surface capable of engaging the wearer's foot and being made of a highly compressible first material; a second longitudinal layer including a toe region, a midfoot region and a heel region, the second longitudinal layer positioned on a lower surface of the first longitudinal layer and having a lower surface capable of engaging the insole of an article of footwear, the second longitudinal layer being made of a material that is less compressible than the first material; and a low friction area positioned on the lower surface of the second longitudinal layer in the heel region of the second longitudinal layer and allowing side-to-side movement.
