This invention relates generally to footwear and, more specifically, to interior lining of footwear.
Over the past few decades, much more attention has been paid to ergonomics, kinesthetics, and other endeavors to tailor human environments to better suit people's bodies and how their bodies move. Such efforts are motivated by desires to make people more comfortable, reduce pain resulting from unnatural positions and movements, and, not the least of which, to improve performance.
One particular area in which tremendous investments and advances have been made in athletic footwear. Only a few decades ago, state-of-the-art basketball shoes had flat rubber bottoms and a flat, canvas high-topped upper. In that same time frame, few people had heard of, let alone owned, a pair of “running shoes.” Certainly, no one had ever heard the term “cross-trainer.” However, today the benefits of exercise are both better understood and better appreciated. Similarly, it is now understood how appropriate footwear not only can enhance athletic performance, improve foot comfort, and reduce foot pain, but it is also appreciated that appropriate footwear can prevent knee injuries, alleviate back pain, and yield countless other benefits.
Greater strides have been made with footwear with soft uppers. A shoe with a soft upper can stretch to conform to a wearer's foot to provide appropriate fit and support. A soft upper also facilitates “proprioception,” which allows the wearer to take advantage of the unconscious perception of movement and spatial orientation gained from stimuli of the footwear appropriately contacting surfaces of the wearer's foot.
On the other hand, advances have not been made as rapidly in the case of more rigidly-shelled athletic wear such as ski boots and skates. Ski boots and skates tend to have semi-rigid or rigid outer shells to securely receive the feet and ankles of the wearer to better translate the wearer's movements to the wearer's skis and skates, respectively. Similarly, protective work boots may include semi-rigid or rigid uppers to protect a worker's feet, or at least may include a semi-rigid or rigid toebox to protect a worker's toes. In the case of hockey skates, a certain rigidity of the upper is desired to protect the foot of the wearer from contact injuries that may be inflicted by sticks, pucks, other players' skates, and other objects. Unlike soft-uppered footwear which can allow a degree of plasticity on the sides and in the toe to accommodate different dimensions of wearers' feet, footwear having a semi-rigid or rigid upper or toebox generally tends to accommodate a largest range of foot dimensions for a given size. Certainly, few could or would tolerate a ski boot or skate having a semi-rigid or rigid shell continually pressing against, for example, the front or top of his or her toes. Such a fit also could increase the potential exposure of the wearer to toe contact injuries. As a result, there tends to be some open space left around the sides and/or the toes of at least some wearers' feet in footwear having a semi-rigid or rigid upper or toebox.
Such open space in such footwear may be unfortunate. Body heat can be lost to the open space, leaving the wearer cold and uncomfortable. Similarly, with the wearer's foot not engaging the inside of the footwear, synergistic benefits of the contact of the foot with the footwear is lost.
Thus, there is an unmet need in the art for footwear with semi-rigid or rigid uppers or toeboxes to engage the foot of the wearer to provide comfort and other sensate benefits.
Embodiments of the present invention provide a toe engaging mechanism for an interior of a footwear item. Particularly in conventional footwear having a semi-rigid or rigid upper or a semi-rigid or rigid toebox, a wearer's toes may be moved upward or forward without contacting the interior of the footwear item, causing the wearer to be unable to derive benefits from having his or her toes at least intermittently contacting the interior of the footwear item. For example, the wearer may lose sensory benefits from having his or her toes contact the interior of the footwear item or lose body heat to the open space surrounding his or her toes. Embodiments of the present invention allow at least some of the toes of the user to contact a panel movably disposed within the interior of the footwear. The panel allows toes of the user to contact an interior surface to retain sensory benefits and/or body heat without uncomfortably restricting the wearer's toes. At the same time, the wearer's toes are removed from an exterior surface of the toebox of the footwear item, protecting the toes from impact injuries that may result from an object striking an outside surface of the toebox. Also, while the wearer's toes contact the panel movably disposed within the interior of the footwear, an open space between the panel and the toebox provides for additionally breathability for the wearer's foot.
More particularly, the present invention provides apparatuses, a system, and a method for engaging a wearer's toes within an interior of a footwear item. A panel configured to extend at least partially across a toebox of the interior of the footwear item is provided. The panel is coupled to an interior of the footwear item such that the panel is positioned inside the toebox to engage an edge of at least one of the wearer's toes. The panel includes a flexible or stretchable material such as neoprene. The attachment mechanism includes at least one of stitching, adhesive bonding, and thermal welding. The attachment mechanism joins the panel to the interior of the footwear item at a plurality of points along at least one of a lower edge of the panel and side edges of the panel, such as by joining the panel to an insole.
Other embodiments of the present invention include a footwear liner equipped with a panel coupled with the lining using an attachment mechanism configured for engaging toes of a wearer. Alternatively, embodiments of the present invention include a footwear system having an upper in which toes of a wearer can be moved without generally contacting an interior of the upper, an outersole, and a panel coupled with an interior of the upper for engaging toes of a wearer. Further, a method of the present invention includes forming a panel, positioning the panel at a location inside the toebox to engage an edge of at least one of the wearer's toes, and securing the panel at the location.
The preferred and alternative embodiments of the present invention are described in detail below with reference to the following drawings.
By way of overview, the present invention provides apparatuses, a system, and a method for engaging a wearer's toes within an interior of a footwear item. A panel configured to extend at least partially across a toebox of the interior of the footwear item is provided. The panel is coupled to an interior of the footwear item such that the panel is positioned inside the toebox to engage an edge of at least one of the wearer's toes.
An embodiment of the present invention, however, includes a toe engaging apparatus 282 for alleviating or eliminating negative consequences from a wearer's toes not contacting an interior surface of the footwear 200. The toe engaging apparatus 282 includes a panel 284 configured to engage the toes (not shown). In preferred embodiments of the present invention, the panel 284 includes one of at least a flexible or a stretchable material. For example, the panel 284 is formed of neoprene or a similar elastic material. Use of a flexible or stretchable material presents a surface configured to engage one or more of a wearer's toes without compressing, constricting, or otherwise negatively applying force to the toes.
The panel 284 is flexibly coupled to an interior of the footwear 200 using at least one attachment mechanism 286. The attachment mechanism suitably includes at least one of stitching, adhesive bonding, and thermal welding for flexibly joining the panel 284 to an interior surface of the footwear 200. In one presently preferred embodiment, the panel 284 is joined to the interior surface of the footwear 200 by attachment mechanisms 286 along at least one of a lower edge of the panel 288 and side edges of the panel 290. For example, the panel 284 could be joined to an insole 292 disposed within the interior of the footwear with the panel coupled by the attachment means 286 to a lower surface and edges of the insole 292 to flexibly support the panel 284 within the interior of the footwear 200.
In one presently preferred embodiment, the panel 284 is not coupled to an upper surface 294 of the interior of the footwear 200. Attaching the panel 284 to an interior surface of the footwear 200 without attaching the panel 284 to an upper surface 294 of the interior of the footwear 200 enables the panel 284 to move more freely within the toebox 280 to allow the wearer's toes (not shown) to be flexibly engaged by the panel.
As shown in
However, as shown in
Disposing the panel 284 near and/or against the toes provides potential benefits. For example, contact between the panel 284 and the toes 150 provides sensory stimuli from the footwear 200 the wearer's toes 150, allowing for proprioception which allows the wearer to take advantage of the unconscious perception of movement and spatial orientation of the toes 150 relative to the footwear 200. Positioning of the panel 284 against the toes 150 effectively closes off open space within the toebox 280 to provide additional thermal insulation for the wearer.
At the same time, the wearer's toes 150 are removed from the toebox 280 of the footwear 200, protecting the wearer's toes 150 from impact injuries that may result from an object striking an outside surface of the toebox 280. Also, while the wearer's toes 150 contact the panel 284 movably disposed within the toebox 280, an open space 285 between the panel 284 and the toebox 280 provides for additionally breathability for the wearer's foot.
Embodiments of the present invention include the toe engaging apparatus 282 (
While the preferred embodiment of the invention has been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is not limited by the disclosure of the preferred embodiment. Instead, the invention should be determined entirely by reference to the claims that follow.
