DETAILED DESCRIPTION OF THE INVENTION

[0018] Referring to the drawings wherein identical reference numerals denote the same elements throughout the various views, FIGS. 1-3 depicts an exemplary rollable, packable, post-activity, water resistant and/or waterproof footwear 10. The footwear 10 includes a shell 12 having a lower shell portion 14 and an upper shell portion 16. The upper and lower shell portions 14, 16 may be made of any suitable water resistant and/or waterproof material, for example, a laminate with stretch poly blend or a Gore-Tex material. The shell 12 may also be lined with an insulating layer 18, such as a stretchable fleece to provide warmth and comfort. It should be appreciated that any suitable number and combination of layers may be used.

[0019] A non-slip sole 20 is positioned on a bottom or footbed 22 of the lower shell portion 14 of the shell 12. The sole 20 may be permanently attached to the bottom 22 of the lower shell portion 14 or detachable. The sole 20 provides a thin protective, non-slip surface for the footwear 10 and may be made of any suitable material that allows the sole 20 to be rolled into a packable unit like shown in FIG. 4E. Example materials include rubber, silicone, polyurethane, thermoplastic polyurethane, a layered material such as felt or moleskin, or any suitable combination or materials. In the case of a detachable sole (like that shown in FIG. 5), the sole 20 may be a more rigid material that can be carried and/or stored separately in a pocket of a user.

[0020] The lower shell portion 14 provides a pocket or envelope for a user's foot to be positioned therein and includes a toe 23 and a heel 24. The upper shell portion 16 is connected to the lower shell portion 14 and wraps around a user's ankle and/or lower leg. For example, the upper shell portion 16 may be hinged to the lower shell portion 14 at the heel 24 of the footwear 10, see FIGS. 4B and 4C. A bottom edge 27 of the upper shell portion 16 may also be connected to an upper band 36 of the lower shell portion 14 using hook and loop fasteners 26 or other suitable connection devices.

[0021] As shown in FIGS. 1-4B, the upper shell portion 16 includes two end flaps 30, 32 and a central back portion 34. The back portion 34 is connected to the heel 24 and the end flaps 30 and 32 wrap around a user's ankle and/or leg and are secured together to envelope the user's ankle and/or leg. The end flaps 30, 32 may be secured together using a cinch cord 38 or other suitable securing means such as hook and loop fasteners. As illustrated, the cinch cord 38 is connected to end flap 30 and extends through eyelets 40 positioned in the end flap 32 and a cord lock 42. The end flaps 30, 32 are tightened around the user's ankle and/or leg by pulling on the cinch cord until a desired tightness is achieved. The cord lock 42 maintains the desired tightness by preventing the cinch cord 38 from withdrawing from the eyelets 40. The cord lock 42 may be disengaged to allow the cinch cord 38 to withdraw and allow the user to remove his/her foot from the footwear.

[0022] The upper shell portion 16 further includes a comfort band 44 along a top edge 46 of the upper shell portion 16 and a strap 47 positioned along the back portion 34. The comfort band 44 may be made of any suitable material, such as fleece, to provide comfort to a user around the user's leg. A first end 48 of the strap 47 is connected to the upper shell portion 16 at the comfort band 44 and extends down the back portion 34 towards the heel 24. A second end 50 of the strap 47 may be removably connected to the back portion 34 by hook and loop fasteners, a snap, a button, or any other suitable type of fastener 49 to move the strap 47 from a stowed position, FIG. 3, to an unstowed position, FIG. 4B. Suitable materials for the strap include MIL-SPEC Polyester or any other suitable material for providing a durable strap.

[0023] As illustrated in FIGS. 4A-4E, the footwear 10 is reconfigurable between a use configuration, FIG. 4A, and stowable and/or packable configuration, FIG. 4E. This is done by loosening and disconnecting the cinch cord 38 that secures the end flaps 30, 32 together. In the case of hook and loop fasteners, simply separating the hook and loop fasteners. With the end flaps 30, 32 released, the upper shell portion 16 is unwrapped, FIG. 4B, and the second end 50 of the strap 47 disconnected from the upper shell portion 16 and moved to the unstowed position. The upper shell portion 16 is then folded down and around the sole 20, FIG. 4C, and the lower shell portion 14 is pushed down to a flatter configuration, FIGS. 4C-4D. The footwear 10 is then rolled from toe 23 to heal 24, FIG. 4D. The strap 47 is then wrapped around the rolled footwear 10, FIGS. 4D-4E, and secured therearound by a fastener such as hook and loop fasteners, snap, button, or the like. The term reconfigurable refers to the combination of material composition, material thickness, and material flexibility being such that the footwear 10 can move between the use configuration and the stowable configuration by hand without tools.

[0024] Referring to FIG. 5, an exemplary rollable, packable, post-activity, water resistant and/or waterproof footwear 100 is shown. The footwear 100 includes a shell 112, a comfort sole 114 on a bottom of the shell 112, a non-slip sole 116 positioned over the comfort sole 114, a hook and loop band and/or strap 118 around a top of the shell 112 to secure the shell 112 around a leg of a user, and a hook and loop band and/or strap 120 around an ankle portion of the shell 112 to tighten the shell around a user's ankle.

[0025] The shell 112 is a soft shell and may be made of any suitable water resistant and/or waterproof material, for example, a Gore-Tex material. The shell 112 may also be made of multiple thin layers to provide warmth, for example, a two-layer shell may include a waterproof outer layer 124 and an inner insulating comfort layer 126, see FIG. 5. A three-layer shell may include a polyester outer shell first layer 128, a waterproof second layer 130, and an insulating and/or comfort third inner layer 132, see FIG. 6. Any suitable materials, such as fleece, may be used as the insulating and/or comfort layer. It should be appreciated that any suitable number and combination of layers may be used. Like footwear 10, the shell 112 includes a lower shell portion 113 and an upper shell portion 115. Unlike footwear 10, the lower and upper shell portions 113, 115 do not separate and instead form a continuous shell.

[0026] The comfort sole 114 is designed to provide the user with a padded foot bed for comfort when walking. The sole 114 may be of any suitable material that provides cushioning, is flexible, and rollable to allow the footwear 100 to be rolled, as seen in FIGS. 7 and 8. For example, the sole 114 may be a polyurethane foam, a viscoelastic polyurethane foam, Ethylene Vinyl Acetate, and Poron to name a few. The sole 114 may also be a layered material such as felt or moleskin.

[0027] The non-slip sole 116 covers the comfort sole 114 and may be detachable, FIG. 5, or permanently attached to the comfort sole 114, FIG. 6. The non-slip sole 116 provides a thin protective, non-slip, surface for the footwear 100 and may be made of any suitable material that allows the sole 116 to be rolled into a packable unit like shown in FIGS. 7 and 8. Example materials include rubber, silicone, polyurethane, and thermoplastic polyurethane. In the case of a detachable sole 116, the sole 116 may be a more rigid material that can be carried and/or stored separately in a pocket of a user.

[0028] Referring to FIG. 6, a pocket 122 is positioned on a rear of the footwear 100. The pocket 122 houses a cover 125 and other accessories such as a hook and loop band and/or strap to cover the footwear 100 and secure the footwear 100 in a rolled state, FIGS. 7 and 8. Alternatively, band 118 may be used to secure the footwear 100 in the rolled state as shown in FIG. 8. The cover 125 may be made of a thin polyester and provides a protective cover over the sole 116 of the footwear 100 as it is being rolled up for transport. The cover 125 prevents dirt from the sole 116 from soiling the shell 112 or anything else the sole 116 may touch during transport.

[0029] Referring to FIGS. 7 and 8, the entire shoe is rolled from the toe to the top of the shell 112. As shown, hook and loop strap 118 is used to wrap around and tighten the footwear into a compact roll for transport by clipping onto a ski boot, carrying in a purse or athletic bag, or in a pocket.

[0030] The following discussion will be specific to skiing; however, it should be appreciated that this is just one example of an activity and is being limited to one example for clarity. In use, the footwear 100 is carried with the skier (for example, attached and/or clipped to a ski boot under ski pants or inside jacket or pocket) and is available for the skier to change into as soon as they hit the bottom of the slopes, thereby providing an immediate, slip-resistant, warm, and comfortable footwear for walking to/from ski lifts as opposed to walking between lifts, around the ski resort, or back to the ski house in uncomfortable boots.

[0031] In the case of other activities such as hockey and basketball, athletes can change into the footwear 100 after games to wear around the rink, arena, or court while preserving athletic shoes for game wear and not taking up space in sports bags. Women can carry the footwear in a purse or jacket pocket to wear home after a night of dancing in heels. Additionally, college students and others who wear fun shoes out to parties need a comfortable shoe to walk home in from the bar or party as an alternative to high heels or sandals and can be packed in a small purse or jacket pocket.

[0032] The footwear 100 is machine washable and may be available in multiple colors and designs to appeal to individual styles. In the case of the detachable sole 116, the sole 114 could be customized with a symbol or writing that would show through a semi-transparent or transparent sole 116. Further, raised symbols and/or writing may be molded into the sole 116 to allow a user to leave imprints in snow, dirt, mud, etc.

[0033] The foregoing has described footwear. All of the features disclosed in this specification (including any accompanying claims, abstract and drawings), and/or all of the steps of any method or process so disclosed, may be combined in any combination, except combinations where at least some of such features and/or steps are mutually exclusive.

[0034] Each feature disclosed in this specification (including any accompanying claims, abstract and drawings) may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.

[0035] The invention is not restricted to the details of the foregoing embodiment(s). The invention extends any novel one, or any novel combination, of the features disclosed in this specification (including any accompanying claims, abstract and drawings), or to any novel one, or any novel combination, of the steps of any method or process so disclosed.
