Abstract
A footbed having a cork foot-contacting surface for use in footwear is provided. The foot-contacting surface includes portions that are altered in thickness in order to form a network of channels that cross the foot-contacting surface of the footbed. The channels facilitate dryness, reduced foot slippage within the footwear, and provide a comfortable fit.
Claims19
An article of footwear having a footbed, the footbed comprising:
- a body having a lateral edge, a medial edge, a toe edge, and a heel edge, wherein the lateral edge is located opposite the medial edge and the toe edge is located opposite the heel edge,
- the body further having a bottom surface and a foot-contacting surface opposite the bottom surface,
- the foot-contacting surface comprising a layer of cork, the layer of cork comprising carbon molecules, portions of the layer of cork having a first thickness and portions of the layer of cork having a second thickness that is less than the first thickness, the first thickness and the second thickness are measured from the bottom surface of the body to the foot-contacting surface of the body,
- wherein the portions of the layer of cork having the second thickness surround the portions of the layer of cork having the first thickness to form a network of channels in the layer of cork at the foot-contacting surface, and wherein the portions of the layer of cork having the second thickness have fewer carbon molecules than the portions of the layer of cork having the first thickness due to an artificial creation of the second thickness.

A footbed for an article of footwear, the footbed comprising:
- a body having a continuous perimeter formed by a lateral edge, a medial edge, a toe edge, and a heel edge, wherein the lateral edge is located opposite the medial edge and the toe edge is located opposite the heel edge,
- the body further having a bottom surface and a foot-contacting surface opposite the bottom surface,
- the foot-contacting surface comprising a layer of cork, the cork comprising plant cells, portions of the layer of cork having a first thickness and portions of the layer of cork having a second thickness that is less than the first thickness, the first thickness and the second thickness being measured from the bottom surface,
- wherein the portions of the layer of cork having the second thickness surround the portions of the layer of cork having the first thickness to form a network of channels in the layer of cork and traversing the foot-contacting surface, and
- wherein, at the foot contacting surface, the portions of the layer of cork having the second thickness have a greater density of the plant cells than the portions of the layer of cork having the first thickness due to an artificial creation of the second thickness.

A footbed for an article of footwear, the footbed comprising:
- a body having a perimeter formed by a lateral edge, a medial edge, a toe edge, and a heel edge, wherein the lateral edge is located opposite the medial edge and the toe edge is located opposite the heel edge,
- the body further having a bottom surface and a foot-contacting surface opposite the bottom surface,
- the foot-contacting surface comprising cork, the cork comprising carbon molecules, portions of the cork having a first thickness and portions of the layer of cork having a second thickness, the first thickness and the second thickness being measured from the bottom surface of the body, the first thickness being at least one millimeter greater than the second thickness, and
- wherein the portions of cork having the second thickness form a network of channels that surround the portions of cork having the first thickness to traverse the foot-contacting surface, the portions of cork having the first thickness comprising at least two-thirds of the foot-contacting surface, and wherein the portions of cork having the second thickness comprise fewer carbon molecules than the portions of cork having the first thickness due to an artificial creation of the second thickness.
