Footwear with elastic footbed cover and soft foam footbed
An article of footwear has a molded outsole which contains a resilient midsole located in the cavity of the outsole and a footbed cover which has a stretch material layer affixed to the outsole and provides a stretch zone. The stretch zone allows the footbed cover to work in conjunction with the resilient midsole to absorb shock upon heel strike or other compression of the midsole to increase comfort. Preferably, the midsole has sections of different hardness in the heel area and the forefoot area.
1. An article of footwear, comprising:
a molded outsole shell having a cavity and a perimeter;
a resilient midsole located in and entirely filling the cavity of the outsole shell and having an upper surface, the midsole comprising a forefoot section having a forefoot section hardness and a heel section having a heel section hardness; the heel section hardness being greater than the forefoot section hardness;
a cover located on the midsole upper surface, the cover having a lower stretch material layer, the stretch material layer being affixed to the perimeter of the outsole shell, and a sock liner upper layer secured to an upper surface of the stretch material lower layer;
whereby downward force on the cover causes resilient deflection of the cover in conjunction with compression of the midsole.
2. The article of footwear of claim 1 , wherein the stretch material layer is located along a portion of the perimeter of the cover proximate to a heel area.
3. The article of footwear of claim 1 , wherein the stretch material layer is located along substantially the entire perimeter of the cover.
4. The article of footwear of claim 1 , wherein the sock liner upper layer has a lesser area than the stretch material lower layer, such that the lower layer extends laterally outwardly from the upper layer along a least a portion of a perimeter of the upper layer.
5. The article of footwear of claim 1 , wherein the stretch material layer comprises one or more of neoprene and spandex materials.
6. The article of footwear of claim 1 , wherein the forefoot section and the heel sections are connected by a scarf joint.
7. The article of footwear of claim 6 , wherein the scarf joint forms a 150. degree. angle.
8. The article of footwear of claim 6 , wherein the scarf joint includes a flex lip provided on the heel section.
