Abstract
A compressible footwear that may include a compressible sole and a compressible upper part that is mechanically coupled to the compressible sole. The compressible sole consisting essentially of multiple compressible cells that are made of a flexible material and have top openings and bottom openings. The multiple compressible cells span over at least a majority of the compressible sole and are configured to undergo a compression while substantially maintaining a thickness of the compressible sole.
Claims20
A method of manufacturing a compressible footwear comprises:
- a. providing a mold defining a lumen for plurality of compressible cells consisting essentially of sidewalls that form top openings and bottom openings;
- b. injecting a melted resin of a pliant material into said lumen within said mold;
- c. cooling down said mold, thereby curing a compressible sole comprising a plurality of compressible cells;
- wherein said plurality of said compressible cells span over at least a majority of said compressible sole and are configured to undergo a compression while substantially maintaining a constant thickness of said compressible sale;
- wherein said plurality of said compressible cells of said compressible sole are configured for reversibly assuming:
- a compressed configuration, and
- an uncompressed configuration;
- wherein in said compressed configuration said plurality of said compressible cells of said compressible sole are effectively collapsed along at least one axis selected from the group consisting of:
- a longitudinal axis across a horizontal plane of said compressible sole and a lateral axis, across said horizontal plane of said compressible sole;
- wherein said compression comprising maintaining essentially constant height of said compressible sole along a vertical plane is essentially maintained;
- wherein said compression comprising maintaining an essentially planar shape of said compressible sole along a vertical axis perpendicular to across said horizontal plane of said compressible sole is essentially maintained;
- wherein said plurality of said compressible cells are not stabilized and wherein compressibility of said plurality of said compressible cells is maintained, thereby preserving ability of said plurality of said compressible cells reversibly assuming said compressed and uncompressed configurations, and
- d. providing a compressible upper part;
- wherein said compressible upper part is foldable, configured to sustain said reversibly assuming said compressed configuration and said uncompressed configurations by said plurality of said compressible cells while collapsing across said horizontal plane of said compressible sole and substantially maintaining said thickness of said compressible sole along a vertical plane and maintaining a planar shape of said compressible sole along;
- wherein a plurality of interfaces formed on a top surface of said compressible sole, configured for engagement of said compressible sole with said compressible upper part of said footwear;
- e. forming at least one connecting element configured for mechanically coupling said compressible sole to said compressible upper part;
- wherein said compressible upper part that is mechanically couplable to said at least one connecting element of said compressible sole;
- wherein said compressible sole in said compressed configuration assumes a compact size, configured for portability of said compressible footwear;
- wherein said uncompressed configuration is a default configuration of said compressible sole and wherein said compressible is spontaneously driven to assume said default configuration, due to intrinsic bias of said plurality of cells;
- wherein said compressible sole in said compressed configuration assuming a size substantially smaller than a size of said compressible sole in said uncompressed configuration;
- wherein said size of said compressible sole in said compressed configuration is smaller by at least seventy percent (70%) than said size of said compressible sole in said uncompressed configuration.
