Adjustable footbeds for footwear
A footbed having at least one of a thickness adjustment panel and a lateral adjustment fin, each configured to be moved between a first configuration and a second configuration, the first and second configurations providing different fits of a shoe into which the footbed is inserted.
1. An adjustable shoe comprising:
an upper and an insole, the insole being removeable from within the upper and comprising:
a forward portion;
a rearward portion; and
a thickness adjustment panel;
wherein the insole has a forward thickness and a rearward thickness;
wherein at least one portion of the thickness adjustment panel is coupled to the insole and the thickness adjustment panel is moveable between a first panel configuration and a second panel configuration;
wherein the thickness adjustment panel overlaps the forward portion of the insole in the first panel configuration;
wherein the thickness adjustment panel overlaps the rearward portion of the insole in the second panel configuration;
wherein the forward thickness is decreased when the thickness adjustment panel is translated from the first panel configuration to the second panel configuration; and
wherein, in the second panel configuration, the thickness adjustment panel is configured to be received at least in part into the rearward portion.
2. The shoe of claim 1 , wherein the thickness adjustment panel is either a unitary piece with the insole and comprised of a deformable material or is hingedly coupled to the insole.
3. The shoe of claim 1 , wherein the thickness adjustment panel is slidable or rotatable relative to the forward portion or the rearward portion.
4. The shoe of claim 1 , wherein the thickness adjustment panel is comprised of EVA foam or polyurethane foam.
5. The shoe of claim 1 , wherein the thickness adjustment panel comprises a size designation imprinted thereon or affixed thereto.
6. A sock liner comprising:
a forward portion;
a rearward portion; and
a thickness adjustment panel;
wherein the sock liner has a forward thickness and a rearward thickness;
wherein at least one portion of the thickness adjustment panel is coupled to the sock liner and the thickness adjustment panel is moveable between a first panel configuration and a second panel configuration to provide periodic adjustment to an inner dimension of a shoe;
wherein the thickness adjustment panel overlaps the forward portion of the sock liner in the first panel configuration;
wherein the thickness adjustment panel overlaps the rearward portion of the sock liner in the second panel configuration;
wherein the forward thickness is decreased from the first panel configuration to the second panel configuration; and
wherein the rearward thickness stays substantially the same or only nominally increases from the first panel configuration to the second panel configuration.
7. The sock liner of claim 6 , wherein the thickness adjustment panel is either a unitary piece with the sock liner and comprised of a deformable material or is hingedly coupled to the sock liner.
8. The sock liner of claim 6 , wherein the thickness adjustment panel is slidable or rotatable relative to the forward portion or the rearward portion.
9. The sock liner of claim 6 , wherein the thickness adjustment panel is comprised of EVA foam or polyurethane foam.
10. The sock liner of claim 6 , wherein the thickness adjustment panel comprises a size designation imprinted thereon or affixed thereto.
11. A system for providing periodic adjustment to a dimension of a shoe comprising:
the shoe; and
a footbed configured to be placed inside the shoe, the footbed comprising:
a first portion;
a second portion; and
a thickness adjustment panel;
wherein the footbed has a first thickness and a second thickness;
wherein at least one portion of the thickness adjustment panel is coupled to the footbed and the thickness adjustment panel is moveable between a first panel configuration and a second panel configuration;
wherein the thickness adjustment panel overlaps the first portion of the footbed in the first panel configuration;
wherein the thickness adjustment panel overlaps the second portion of the footbed in the second panel configuration;
wherein the first thickness is decreased from the first panel configuration to the second panel configuration; and
wherein, in the second panel configuration, a positive surface feature of the thickness adjustment panel is configured to be received at least in part into a negative surface feature of the second portion.
12. The system of claim 11 , wherein the thickness adjustment panel is either a unitary piece with the footbed and comprised of a deformable material or is hingedly coupled to the footbed.
13. The system of claim 11 , wherein the thickness adjustment panel is slidable or rotatable relative to the first portion or the second portion.
14. The system of claim 11 , wherein the thickness adjustment panel is comprised of EVA foam or polyurethane foam.
15. The system of claim 11 , wherein the thickness adjustment panel comprises a size designation imprinted thereon or affixed thereto.
