The toes and soles of shoes or boots often become worn due to friction in these areas. When bowling, often a bowler will often drag their shoe while the wearer is in the final stages of a bowling approach. In such an instance, the trailing shoe is frequently vertical or inverted such that the toe drags behind the bowler across the surface of the lane. Ordinary shoes frequently wear out over time as the friction from the dragging motion frays the toe material and separates the outsole from the upper. When playing sports such as soccer, continued contact of the ball with the toe area can wear down the toe and cause holes to form. Work boots often see wear in the toe before other places as the toe region initially interacts or rubs against items while walking or moving. The bottom of the outsole, especially the forepart region, typically loses traction due to extensive contact with the ground, especially when interacting with harder surfaces such as asphalt or concrete.
What occurs in the examples above is that often the rest of the shoe is in relatively good condition, however, this wear or holes in the toe or outsole region typically requires the disposal of the entire shoe, causing unnecessary waste as well as a financial expense with the purchase of a new pair of shoes. This cost is expanded if insoles or other additions have been added to the shoe. Typically the toe region is made up of a similar number of layers, which are of the same protective quality as the rest of the shoe. Often the toe region does not have any protective layers which would prolong the life of this region, which ignores the contact and friction that the toe region experiences. Similarly, the forepart region of the sole is typically made of the same material as the heel and arch region, ignoring the fact that often the forepart region is the primary part of the shoe which presses against the ground and propels the user forward, causing extensive friction and wear in this region.
Typically, the material a shoe is made of is not interchangeable, and thus the physical characteristics and friction coefficients are constant as well. This can be limiting for individuals who want to use the same shoe for a variety of terrains or purposes. This can also limiting for various activities such as bowling where the friction coefficient of different parts of the outsole or upper tend to be different depending on one's bowling style. Thus, stores are forced to keep in stock a wide range of shoes with materials with different friction coefficients in a number of places around the shoe, or the consumer is stuck with choosing between a select number of options which may not fit their needs or preferences.
Thus, what is needed is a footwear cover that prolongs the life of the toe and/or outsole region of the shoe. Additionally, this footwear cover should have the option of coming in a variety of traction characteristics. This footwear cover could be removable or permanent as either method could prolong the life, reduce the cost of buying a whole new pair of shoes, and diversify the traction coefficients. Additionally useful in the bowling field would be a footwear cover which aids in the shoe's transition to a vertical or inverted position.
The present invention relates to a footwear cover. In some embodiments the footwear cover is attached to and covers at least a portion of the upper toe region of a shoe. In other embodiments the footwear cover is attached to and covers at least a portion of the upper toe region and the outsole of a shoe. In some embodiments the footwear cover has different physical characteristic from the upper toe region to which it is fastened, and in other embodiments the footwear cover has different physical characteristics from both the upper toe region and the outsole.
In some embodiments one or more shoes and one or more footwear covers are provided in a kit.
In some embodiments the footwear cover is permanently attached to the shoe and in others it is removably attached. In some embodiments the footwear cover is removably attached by a fastener selected from the group consisting of adhesive, magnet, hook and pile, nipple and eyelet, fastening ridge, rivet, pocket, or combinations thereof.
In some embodiments the footwear cover is a single layer and in other embodiments the footwear cover is more than one layer. In some embodiments where the footwear cover is more than one layer the layers are made of the same material and in other embodiments the layers are made of different materials.
In some embodiments the footwear cover increases the coefficient of friction in comparison to the area it covers and in other embodiments it decreases the coefficient of friction. In some embodiments the footwear cover is supplied with textured features which vary the coefficient of friction of the cover.
In some embodiments the footwear cover is all one section and in other embodiments the footwear cover has different sections. In some embodiments the different sections have the same physical characteristics and in others they have different physical characteristics.
In some embodiments the footwear cover is flexible such that it fits a variety of areas and in others it is rigid, molded to fit only one specific area.
In some embodiments only one footwear cover is provided and in others more than one is provided. In some embodiments where more than one cover is provided all of the covers have the same physical characteristics and in others they have different physical characteristics.
In some embodiments a single footwear cover is designed fit either a left or a right shoe, in other embodiments a single footwear cover is designed to match the handedness of a specific shoe. In some embodiments at least two covers are provided, one designed to match the handedness and fit the right shoe and the other to match the handedness and fit the left shoe.
In some embodiments where the footwear cover attaches to the bottom of the outsole the outsole is recessed and the cover fits inside of the recess.
As different sized shoes have different area sizes the areas are best described relating the spacing of an average user's foot inside the different sized shoes. In some embodiments the toe region of the upper or outsole is generally defined as the area between a line draw horizontally across the front most part of the shoe to a line drawn horizontally across and intersecting with the joint between the distal and proximal phalanx of an average user big toe. In other embodiments the toe region of the upper or outsole is generally defined as the area between a line draw horizontally across the front most part of the shoe to a line drawn horizontally across and intersecting with the joint between big toe's the proximal phalanx and first metatarsal of an average user. In other embodiments the toe region of the upper or outsole is generally defined as the area between a line draw horizontally across the front most part of the shoe to a line drawn horizontally across and intersecting with the joint between the first metatarsal and first cuneiform bone. In all of the above embodiments the forepart region begins where the toe region ends. In some embodiments the forepart region extends back to a selected line in front of the heel region. In most embodiments the heel region is defined as the area around where the heel contacts the ground. The arch region is the area between the heel and forepart regions.
In some embodiments there is one footwear cover 5 and in other embodiments there are multiple footwear covers 5. The location and material composition of footwear cover 5 is varied depending on the embodiment of the invention, which will be discussed in more detail below. Similarly, the length and starting position of footwear cover 5 is varied in the various embodiments. In some embodiments footwear cover 5 is fixed on shoe 7 and in other embodiments footwear cover 5 is removable. In other embodiments a footwear kit is provided with a pair of shoes and one or more footwear covers 5. While the figures only display a single shoe, in some embodiments of the invention both a left and right shoe are provided, each shoe having an intrados edge 11, which faces the other shoe when wearing the shoes, and an extrados edge 12, which faces away from the other shoe when wearing the shoes. In some embodiments both the left and right shoe are provided with a footwear cover 5, in other embodiments both a left and right shoe are provided but only one shoe is provided with a footwear cover 5, in other embodiments one or more footwear covers 5 are provided but only one shoe is provided, and in other embodiments only a footwear cover 5 is provided.
In some embodiments footwear cover 5 can fit either the left or right shoe. These embodiments are useful as they allow a reduction in the different types of cover 5's which need to be manufactured, stocked, and purchased. In other embodiments, footwear cover 5 is designed to fit a specific shoe. These embodiments allow for greater fit and conformance to the specific area and shape of the left or right shoe.
In some embodiments footwear cover 5 is made, at least in part, of a low friction material. Low friction materials include polymers such as polyethylene, polypropylene, polyurethane, polyvinylchloride, polytetrafluoroethylene, polyethylene terephthalate, polytetrafluoroethylene; smoothed leathers; metals such as steel; smoothed or shellacked wood; additives which decrease the coefficient of friction of a material; or combinations thereof. These embodiments are useful when sliding is desired as the function of footwear cover 5, such as when dancing or bowling. In other embodiments footwear cover 5 is made, at least in part, of a high friction material. High friction materials include rubber; roughed leather; fabrics such as cotton, wool, polyester, or denim; additives which increase the coefficient of friction of a material; or combinations thereof. These embodiments are useful when increased traction or grip is desired as the function of footwear cover 5, such as when hiking or running.
In some embodiments the whole footwear cover 5 is made of the same composition of material, and in other embodiments footwear cover 5 comprises sections made up of different material compositions. Embodiments with all the same material composition are useful for ease and cost of production and in most cases where the entire cover is used for protection or other purposes. Embodiments with different sections are useful for giving different traction characteristics or different protective properties to the different areas of footwear cover 5. For example, when bowling, the positioning of the dragging foot in relationship to the lane effects the throw of the bowler, thus having different traction characteristics on different sections of footwear cover 5 can help physically guide the bowler to the ideal position based on the feel of the cover as it interacts with the ground.
In some embodiments footwear cover 5 is a single layer and in other embodiments more than one layer. In some embodiments all of the layers are made of the same material, in other embodiments at least some the layers are different from one another, and in other embodiments all of the layers are different from one another. Embodiments with the materially the same layer are useful for ease of construction and a reduction in the types of material which need to be stored and used. Embodiments with materially different layers are important when each layer has a specific function. For example, one embodiment could have a rough external layer for protection, a middle waterproof or padded layer, and a bottom layer which has a hook and pile system to fasten to shoe 7.
In some embodiments, footwear cover 5 is made of the same material as upper 10, in some embodiments footwear cover 5 is made of the same material as outsole 9, and in some embodiments footwear cover 5 is made of a different material from both upper 10 and outsole 9. Embodiments where footwear cover 5 is made from material different from both upper 10 and outsole 9 are beneficial as they give different traction characteristics, protective properties, or other physical characteristics essential to the function of footwear cover 5. Embodiments where footwear cover 5 is made of the same material of either upper 10 or outsole 9 are useful as it allows footwear cover 5 to better blend in with these areas and gives a more aesthetically pleasing shoe. In some embodiments upper 10 is different materials, and in some of these embodiments footwear cover 5 is different from only one type of upper 10 material or a material in a specific section of upper 10, such as upper toe region 6.
In some embodiments footwear cover 5 is flexible and can be shaped to the specific area it covers. These embodiments are useful as they allow the same footwear cover 5 to shield various regions which gives versatility to the same manufactured product. In other embodiments footwear cover 5 is rigid and is molded such that it can only be applied to the specific area it was designed and molded. These embodiments give greater protection and are useful for embodiments where maximum upper toe region 6 protection is required.
As seen in
Similarly, as seen in
In some embodiments footwear cover 5 is a strip that covers only a portion of upper toe region 6, and in other embodiments footwear cover 5 covers the entire toe region 6. Embodiments where only a portion of upper toe region 6 is covered are important when a specific traction characteristic or other function is desired for a specific section of upper toe region 6, such as a footwear cover 5 which guides a bowler by providing tactile feedback regarding the position of the toe in relation to the lane. Embodiments where the entire upper toe region 6 is covered by footwear cover 5 are important when overall protection or longevity is needed for upper toe region 6, such as for construction boots.
Similarly, in some embodiments footwear cover 5 is a strip that covers only a portion of outsole 9, and in other embodiments footwear cover 5 covers the entire outsole 9. Embodiments where only a portion of outsole 9 is covered are important when a specific protective property or traction characteristic or other function is desired for a specific section of outsole 9, such as greater protection under the ball of the big toe. Embodiments where the entire outsole 9 is covered by footwear cover 5 are important when overall traction characteristics, protection, or longevity is needed for outsole 9, such as when hiking through different terrain.
In one embodiment, footwear cover 5 is permanently fastened in to shoe 7 such that a user of the shoe is unable to reconfigure footwear cover 5. In some embodiments the fastening is by sewing, in others by gluing, and in others by stapling, nailing, or other similar fastening methods. These embodiments are useful when one type of footwear cover 5 at one location is needed, and its stability and durability are the main concerns.
In other embodiment, footwear cover 5 is removably fastened, such that a user of the shoe can replace, reconfigure, or reposition footwear cover 5. In one embodiment the fastening mechanism is an adhesive substance such as a glue, tape, or sticky putty. In another embodiment the fastening mechanism is a magnetic attachment. In another embodiment the fastening mechanism is a hook and pile fastener system such as the brand Velcro®. In another embodiment the fastening mechanism is a pocket in shoe 7 where footwear cover 5 fits into. In yet another embodiment the fastening mechanism is a nipple and eyelet mechanism such as a button, snap or clasp. In other embodiments footwear cover 5 is equipped with a fastening ridge 15 which fastens onto shoe 6. In other embodiments footwear cover 5 is fastened by a rivet. These removably fastening embodiments are useful when various types of footwear covers 5, or covers at various positions are needed, as these embodiments give flexibility to the user of shoe 7.
In one embodiment, reversible fastening footwear cover 5 provides interchangeability of footwear cover 5 with other footwear covers 5 having different traction or feedback characteristics. In another embodiment, reversible fastening footwear cover 5 allows the user to replace worn out or damaged footwear covers 5. In another embodiment, reversible fastening footwear cover 5 gives the user the ability to reposition footwear cover 5 in various positions.
In some embodiments footwear cover 5 and shoe 7 are sold separately. These embodiments allow the user to purchase the type of footwear cover which would best suit the needs of the user. In other embodiments, a kit is provided with at least one shoe 7 and at least one footwear cover 5. In some embodiments only one footwear cover 5 is provided. These embodiments are useful when only one shoe requires a footwear cover and only type of the footwear cover is required. In other embodiments the kit contains two or more footwear covers 5. In some embodiments the various footwear covers 5 have generally the same material composition, and in others they have different material compositions. Embodiments where the various footwear covers 5 have the generally same material composition are useful when both shoes require the same type of protection, such as work boots, or when a specific type of footwear cover 5 would need to be replaced frequently. Embodiments with different compositions of the various footwear covers 5 are useful as they allow the user to be prepared for various surface environments, or to use the different covers in different circumstances while using the same, more costly, shoe 7.
As seen in
In one embodiment the bottom of outsole 9 is recessed such that when footwear cover 5 is attached within the recess it maintains flushness with the bottom of outsole 9. In one embodiment the portion of footwear cover 5 which attaches to the bottom of outsole 9 has a different surface characteristic than the portions of footwear cover 5 on the front and top of shoe 7. In another embodiment the entire surface of footwear cover 5 has a uniform surface characteristic.
In one embodiment the shape of footwear cover 5 is square, in another embodiment the shape is rectangular, in another embodiment triangular, in another embodiment oval, in another embodiment circular, and in other embodiments footwear cover 5 has no defined shape. The different shapes and sized are important as different functions will require different shaped footwear covers. In most embodiments the shape of footwear cover 5 is designed to match the general shape of the region which it covers.
