Layers with cells in footwear

Abstract

In some examples, a sole layer for a footwear includes a housing structure, a cell in the housing structure, a solid support inside the cell to maintain a shape of the cell, and an inlet to the cell to receive an injected material to dissolve the solid support.

What is claimed is: 
     
         1 . A sole layer for a footwear, comprising:
 a housing structure;   a cell in the housing structure;   a solid support inside the cell to maintain a shape of the cell; and   an inlet to the cell to receive an injected material to dissolve the solid support.   
     
     
         2 . The sole layer of  claim 1 , wherein the solid support has a lattice shape. 
     
     
         3 . The sole layer of  claim 1 , wherein the cell is a first cell, the solid support is a first solid support, and the inlet is a first inlet, the sole layer further comprising:
 a second cell in the housing structure;   a second solid support inside the second cell to maintain a shape of the second cell; and   a second inlet to the second cell to receive an injected material to dissolve the second solid support.   
     
     
         4 . The sole layer of  claim 3 , wherein the first and second cells are to receive respective materials through the first and second inlets after dissolution of the first and second solid supports. 
     
     
         5 . The sole layer of  claim 1 , wherein the sole layer is to be attached as part of a plurality of layers in a sole of the footwear during manufacture of the footwear. 
     
     
         6 . An assembly comprising:
 a footwear comprising a sole including a plurality of layers, a first layer of the plurality of layers comprising:
 a plurality of cells; 
 solid supports inside respective cells of the plurality of cells; and 
 inlets to the respective cells to receive injected materials to dissolve the solid supports. 
   
     
     
         7 . The assembly of  claim 6 , wherein upon dissolution of the solid supports, the inlets are to receive additional materials to fill the respective cells. 
     
     
         8 . The assembly of  claim 7 , wherein the further materials are selected from among a fluid, a foam, a plastic, and wax. 
     
     
         9 . The assembly of  claim 7 , wherein the further materials in at least two of the respective cells are of different types. 
     
     
         10 . The assembly of  claim 6 , wherein the inlets comprise self-sealing membranes. 
     
     
         11 . The assembly of  claim 6 , wherein the injected materials to dissolve the solid supports comprise liquid. 
     
     
         12 . The assembly of  claim 6 , further comprising an injection kit comprising an injection element to inject a first material into a first cell of the plurality of cells after the solid support in the first cell has been dissolved. 
     
     
         13 . The assembly of  claim 12 , wherein the injection kit further comprises a second injection element to inject a second material into a second cell of the plurality of cells after the solid support in the second cell has been dissolved, wherein the first material is different from the second material. 
     
     
         14 . A method of forming a sole for a footwear, comprising:
 providing a sole layer of the sole, the sole layer comprising a cell including an inner cavity to receive a material injected through an inlet, to customize support for a foot of a user; and   arranging a solid support in the inner cavity of the cell, the solid support to break up inside the inner cavity of the cell in response to an applied force.   
     
     
         15 . The method of  claim 14 , wherein the solid support before breaking up is to provide support to prevent collapse of the cell.
