Articulating footwear for sports activity
A boot includes an upper formed of articulating panels that permit portions of the boot to move in substantial independence from one another in response to loads experienced by the boot. The boot generally comprises a sports boot that is positioned around a wearer's foot for coupling to an external appliance, such as a snowboard, wakeboard, skating appliance (such as a blade or wheels), or any other appliance.
1. A footwear device that couples to a sport board, comprising:
an upper positioned on a sole, wherein the upper is configured to receive a foot and is at least partially formed of two or more panels that can move relative to one another to permit the upper to deform in response to loads, wherein the panels include overlay panels and underlay panels located at least partially below the overlay panels, and wherein the overlay panels can move relative to the underlay panels wherein the underlay panels are connected via seams positioned below the overlay panels, and wherein the underlay and overlay panels include:
(a) at least one side overlay panel positioned along a lower side and toe region of the footwear device;
(b) at least one upper overlay panel positioned along an upper side region of the footwear device;
(c) a one front underlay panel positioned in a toe region of the footwear device;
(d) a side underlay panel positioned along a side region of the boot; and
(e) an upper underlay panel positioned along an upper region of the boot;
wherein the front underlay panel, the side underlay panel, and the upper underlay panel all define an outermost surface of the footwear device.
2. A footwear device as in claim 1 , further comprising a tongue attached to the upper, wherein the tongue is positioned adjacent an upper region of the footwear device and wherein the tongue includes two or more distinct regions that are connected to one another along predetermined connection zones, the regions configured to move relative to one another, wherein the regions can each be manufactured of a material having desired structural characteristics specifically suited to the location of the region on the tongue.
3. A footwear device as in claim 1 , wherein the panels are molded of non-woven material.
4. A footwear device as in claim 1 , wherein the overlay panels are made of a material that is more flexible than a material of the underlay panels.
5. A footwear device as in claim 1 , wherein the underlay panels are made of a material that is more flexible than a material of the overlay panels.
6. A footwear device as in claim 1 , wherein cut-out regions are positioned between the underlay panels to permit relative motion between the underlay panels.
7. A footwear device as in claim 6 , wherein the cut-out regions are filled with a material that is flexible.
