Definitions
- the present disclosure relates to footwear and footwear accessories, and more particularly to footwear and footwear accessories with magnetic components that selectively secure the shell of the footwear around a wearer's foot.
- adjustable fasteners for selectively adjusting the size of the foot compartment defined by the footwear' s sole and shell, and thereby adjusting the degree to which the footwear is secured around a wearer's foot and/or configured to permit ready insertion or removal of a wearer's foot into/from the foot compartment.
- Examples of commonly used adjustable fasteners are laces, buckles, zippers, and hook-and-loop straps.
- adjustable fastening mechanisms provide a mechanism for the wearer to selectively adjust the "fit" of the footwear to suit the wearer's current preferences, they typically require manual manipulation, such as by the wearer or another person, to secure/tighten and/or release/loosen the fastener and thereby select and/or restrict the size of the footwear's foot compartment.
- slip-on footwear typically provides a much looser fit, namely, a foot compartment that is only loosely secured around the wearer's foot and/or which does not extend around the heel portion of the wearer' s foot.
- Some wearers of footwear with laces or similar conventional adjustable fasteners may not be able to and/or want to manually manipulate the fasteners to don and/or remove the footwear.
- a wearer may lack the physical and/or mental ability to provide the required manual manipulation.
- Other wearers simply may not want to exert the time or effort to do so.
- the primary solution is simply to maintain the fastener in a released, or loosened, configuration that defines a foot compartment that is oversized relative to the wearer's foot, and thereby does not securely fit around the wearer's foot.
- a magnetic footwear fastener includes a pair of magnetic couplers that are selectively (magnetically) coupled together by the magnetic attraction between the magnetic couplers.
- the magnetic footwear fasteners may be utilized with footwear to selectively secure the footwear in a closed, or sized, configuration around a wearer's foot when the magnetic coupling regions of the pair of magnetic couplers are magnetically coupled together.
- the magnetic couplers also include mechanical coupling regions that are configured to be attached to footwear, either in a temporary or permanent manner. When the magnetic couplers are temporarily, or removably, coupled to the footwear, the magnetic footwear fastener may be described as a magnetic footwear accessory.
- each magnetic coupler of a magnetic footwear accessory may include one or more coupler eyelets through which the footwear's lace extends.
- the mechanical coupling regions thereof may be integrated into the shell or other upper region of the footwear.

- magnetic footwear fasteners 60 with, and optional partial or complete integration of magnetic footwear fasteners 60 into, footwear 10 according to the present disclosure is discussed in more detail herein.
- footwear 10 generally includes a sole 20 and a shell, or upper, 22.
- the shell and the sole define a foot compartment 24 that is sized to receive a wearer's foot when the footwear is worn.
- the foot compartment may be described as including a forefoot region 26, a midfoot region 28, and a heel region 30, with these regions generally corresponding to respective forefoot, midfoot, and heel portions, or regions, of a wearer' s foot when it is received within and operatively positioned within the foot compartment.
- a wearer' s foot When so received within the foot compartment, a wearer' s foot generally is positioned on and/or above the sole, and the shell extends at least substantially, if not completely, around the sides and top portion of the wearer's foot.
- the shell defines a foot opening 32, through which a wearer's foot passes when the wearer' s foot is inserted into the footwear's foot compartment, and through which the user' s ankle or lower leg extends when the footwear is worn.
- footwear 10 includes a channel 34 that extends from the foot compartment, along at least a portion of the midfoot region, and toward the forefoot region 26 of the footwear.
- the length and width of channel 34 may vary within the scope of the present disclosure.
- channel 34 may take the form of a narrow slit between adjacent, or even overlapping, edges 35 of vamp portions 37 of the footwear' s upper.
- channel 34 may be much wider, with the channel defining an opening, or passage, that extends above a substantial portion of the top of the wearer's foot when the footwear is worn. In such a configuration, edges 35 are spaced farther away from each other, and footwear 10 typically will include a tongue 36 that extends between the edges.
- footwear 10 further includes a tongue 36, which extends within and/or spans channel 34.
- tongue 36 which extends within and/or spans channel 34.
- tongue 36 additionally or alternatively may extend within channel 34 and/or above channel 34.

- tongue 36 may be fixedly coupled to the shell 22 of the footwear, such as within forefoot region 26.
- tongue 36 may be stitched to the shell, with the tongue extending from the forefoot region to the foot opening 32 within the foot compartment 24 and beneath, within, and/or above channel 34.
- Footwear 10 may further include a plurality of footwear eyelets 38, such as which may extend on generally opposed lateral sides of channel 34, and at least one lace 46 that is selectively passed through the footwear eyelets to assist in securing the footwear in a sized configuration.
- Footwear 10 that includes footwear eyelets 38 and lace 46 may be described as laced footwear 12.
- laced footwear 12 may include the same components and/or features as other footwear 10 that is illustrated and/or described herein.
- magnetic footwear fasteners 60 facilitate donning and/or removal of footwear 10.
- the magnetic footwear fastener 60 may permit the footwear to be quickly and repeatedly secured in a preselected coupled configuration without requiring tying of laces, buckling of buckles, etc. Instead, the footwear may be secured in the coupled configuration simply by the magnetic engagement of the magnetic couplers 62.
- the removal of a wearer' s foot from footwear 10 may be performed by a wearer in a hands-free manner, that is, without requiring the wearer to use his/her hands to engage the footwear, such as to untie a lace, to unbuckle a buckle, and/or otherwise manually manipulate the footwear or a fastener thereof.
- footwear 10 with at least one magnetic footwear fastener 60 may be configured to be removed from a wearer' s foot by flexing the wearer's foot so that the wearer' s foot causes at least one pair of magnetic couplers 62 to become uncoupled and thereby permit a portion of the footwear's upper, such as a tongue, cap, or flaps, to pivot to increase the size of the footwear' s foot opening.
- the force exerted by the wearer' s foot during this flexing motion may configure the footwear to an open, or uncoupled, configuration.
- An example of a suitable flexing motion is plantar flexing of the wearer's foot, in which the wearer' s foot is flexed to extend the wearer's toes away from the wearer' s leg.
- a wearer may use his/her other foot to engage the heel of the footwear while the wearer flexes his/her foot to remove it from the footwear, with the other foot effectively restricting pivoting of the footwear, for example, so that the flexing action does not significantly lift the footwear' s heel off the ground.
- a wearer may choose to use the wearer' s hands to manually uncouple the magnetic couplers and pivot the footwear's tongue or other upper structure to increase the size of the footwear' s foot opening and/or foot compartment for removal (and/or (re)insertion) of the wearer' s foot.
- the magnetic footwear fasteners 60 may be utilized as magnetic accessories 64 for laced footwear, namely, footwear with a plurality of footwear eyelets that conventionally receive a lace that is selectively tightened and tied to secure the lace in a tightened configuration, and which are selectively untied and loosened to configure the footwear to an untied, or loosened, configuration.
- the magnetic accessories 64 may be utilized to permit repeated coupling of the footwear to a tightened, or sized, configuration without requiring the repeated tightening, tying, untying, and/or loosening of the footwear's lace.
- the magnetic accessories 64 may further permit hands-free uncoupling of the magnetic accessories to configure the footwear to a loosened, or unsized, configuration.
- at least one, if not both, magnetic coupler(s) 62 of a magnetic footwear fastener 60 may be integrated into the footwear 10, such as into the footwear' s shell, vamp, tongue, or other upper portion.
- the magnetic coupler(s) 62 may be referred to as an integrated magnetic coupler.
- an "integrated" magnetic coupler cannot be removed from the footwear without damage to or destruction of a portion of the footwear, the magnetic coupler, or structure that mechanically secures the magnetic coupler to the footwear.
- the magnetic footwear fastener 60 when both magnetic couplers 62 are integrated into footwear 10, the magnetic footwear fastener 60 may be referred to as an integrated magnetic footwear fastener 66. As also discussed in more detail herein, such as in connection with Figs. 16-17, when only one of the magnetic couplers 62 of a magnetic footwear fastener 60 is integrated into footwear 10, the magnetic footwear fastener may be referred to as a partially integrated magnetic footwear fastener 68.
- footwear 10 may or may not include footwear eyelets and/or a lace, although the footwear still may include a foot compartment sizing mechanism that is selectively utilized to adjust the size of the footwear's foot compartment.
- magnetic footwear fastener 60 includes at least one magnet 72, optionally may include a plurality of magnets 72, and further optionally may include a magnetic material 74.

- one magnetic coupler 62 may include at least one magnet 72, and the other (mating and/or complementary) magnetic coupler 62 of the magnetic footwear fastener 60 may include a magnetic material 74.
- Magnets 72 may be discrete magnets, sheet magnets, bar magnets, programmed or correlated magnets (such as which include an ordered series or group of discrete magnetic dipoles), a Halbach (or Halbach-like) array of magnets, an array of magnets oriented to provide a directed magnetic field and/or directed magnetic flux, or any suitable magnet configuration or assembly.
- each magnetic coupler may include the same number, type, and/or array of magnets, with magnets of the pair of magnetic couplers being arranged to be complementary to each other, namely, to draw the magnetic coupling surfaces of the magnetic couplers together (as opposed to repelling or otherwise urging the magnetic coupling surfaces away from each other).
- Each magnetic coupler 62 includes a coupler body, or housing, 70, with the respective magnets 72 and/or magnetic material 74 being secured to or within the body or forming at least a portion of the body.
- the body 70 of each magnetic coupler may define a cavity, or internal compartment, 76 within which the respective magnets 72 and/or magnetic material 74 are located. Cavity 76 additionally or alternatively may be referred to as a magnet compartment 76, channel 76, magnet-receiving socket 76, and/or magnet receptacle 76.
- coupler body 70 may define more than one magnet cavity 76, with each cavity having a distinct magnet and/or magnetic material position therein.
- magnet(s) 72 and/or magnetic material 74 may be secured to, form at least a portion of, and/or project from the exterior 78 of the coupler body 70.
- Magnetic couplers 62 include and/or define at least one coupling region 88.
- magnetic couplers 62 have a region that is configured to be magnetically coupled to the corresponding coupling region of a corresponding magnetic coupler when a magnetic footwear fastener 60 is in its coupled configuration.
- the coupling region 88 is a region of each magnetic coupler 62 that is configured to provide a strong, and perhaps the strongest, magnetic attraction with the coupling region of a corresponding magnetic coupler 62 of a magnetic footwear fastener 60.
- the strength of the magnetic attraction (i.e., the strength of the magnetic bond) between the coupling regions 88 of the magnetic couplers 62 of a magnetic footwear fastener 60, when in the coupled configuration may be at least 50%, at least 75%, at least 90%, or at least 100% stronger than the strength of a magnetic attraction between other portions of the magnetic couplers if such other portions are placed in physical contact with each other.
- the coupling region 88 may include a coupling surface 90, with the coupling surfaces 90 of the magnetic couplers of a magnetic footwear fastener 60 being sized and/or shaped to correspond to each other to promote a secure magnetic bond between the surfaces. It follows then that when these coupling surfaces are magnetically coupled together, the magnetic couplers will be connected firmly together.
- Coupling region 88 additionally or alternatively may be referred to as a mating region 88, and coupling surface 90 additionally or alternatively may be referred to as a mating surface 90.
- Magnetic coupling surface 90 additionally or alternatively may be or form a portion of the exterior surface of the body 70 of the magnetic coupler, and thus magnetic coupling surface 90 further additionally or alternatively may be referred to as an exterior, or external, magnetic coupling surface 90.
- Magnetic footwear fasteners 60 may be described as being coupled or secured when the corresponding mating regions and/or magnetic coupling surfaces of the fastener' s pair of magnetic couplers 62 are magnetically secured together. Magnetic footwear fasteners 60 may be described as being uncoupled or unsecured when the corresponding mating regions and/or magnetic coupling surfaces of the fastener's pair of magnetic couplers are separated or otherwise not magnetically secured together.
- Magnetic couplers 62 optionally may include a coating, cover, and/or covering material 80, for example, to protect at least the magnetic coupling surface 90 of the magnetic coupler from the environment, to reduce wear of any magnets 72 and/or magnetic materials 74 of the magnetic coupler, and/or to shield and/or redirect the magnetic field of the magnets.
- covering materials 80 for environmental protection and general mechanical protection include, and/or may be, coatings, fabric, polymeric material, plastic, epoxy, rubber, and the like.
- covering materials for magnetic shielding include high magnetic permeability materials and ferromagnetic materials.
- a majority, at least 70%, at least 80%, at least 90%, at least 95%, or even all of the magnets and/or magnetic material of a magnetic coupler 62 may be enclosed or housed within the magnetic coupler and/or otherwise physically shielded from the environment external the magnetic coupler by covering material 80.
- the magnetic coupling region 88 and/or magnetic coupling surface 90 of a magnetic coupler 62 may be defined at least in part by the positioning of the magnet(s) 72 and/or magnetic material 74 of magnetic coupler 62.
- the size, type, number, and orientation of the magnets in a magnetic coupler may affect the magnetic field that is emitted from the magnetic coupler.
- the magnets may be selected and/or oriented to concentrate the magnetic field at or proximate the magnetic coupling surface 90 and/or to reduce or limit the magnetic field in one or more other regions of the magnetic coupler (such as on other exterior portions of the body of the magnetic coupler, portions of the magnetic coupler that face away from the footwear's foot compartment when the magnetic footwear fastener is in a coupled configuration, and/or portions of the magnetic coupler proximate the mechanical coupling region thereof).
- Arrays of magnets 72 having such a configuration may be referred to as a magnetic array and/or a plurality of magnets that has a directed magnetic field and/or a directed magnetic flux.
- including a plurality of bar (or similar) magnets with generally parallel axes in which adjacent magnets have oppositely aligned poles may concentrate the magnetic field near the coupling region of the magnetic coupler' s body 70 (and/or define such a magnetic coupling region 88 of the body) while reducing the magnetic field in regions of the body that extend parallel to the axes and/or that are spaced farther away from the region of concentrated magnetic field. These regions of reduced magnetic field thus will not be drawn together (magnetically attracted) as strongly as the coupling surfaces of the magnetic couplers.
- reducing the magnetic field emitted by other portions of the magnetic couplers may tend to reduce the likelihood of other magnetic materials being coupled to the magnetic couplers.
- Reducing the magnetic field additionally or alternatively may reduce the distance from which the magnetic couplers are drawn together simply by the emitted magnetic field.
- too strong of an attraction may cause the magnetic couplers to be drawn into a coupled configuration even when a user desires to maintain the footwear to which the magnetic couplers are attached in a loosened configuration.
- Arranging a series of magnets with alternating poles also may assist in drawing the corresponding coupling regions 90 of a pair of magnetic couplers 62 together to a predefined, or desired, aligned orientation, as the alternating poles may assist with the coupling regions self-aligning, or being magnetically biased to such an aligned orientation.
- such an alternating pole configuration may reduce the likelihood of the magnetic couplers sliding apart from each other (such as responsive to external forces that might cause the coupling regions to separate other than when the user is intending to uncouple the coupling regions) and/or may increase the need to pivot, rotate, or otherwise "peel" the coupling regions apart when it is desired to uncouple the magnetic couplers.
- a suitable arrangement of a series (plurality) of magnets to concentrate the magnetic field at the magnetic coupling surface 90 and to minimize the magnetic field at other portions of the magnetic coupler's body (such as at the mechanical coupling region and/or other portion of the magnetic coupler distal or otherwise spaced apart from the magnetic coupling surface) is a Halbach array, or Halbach array arrangement, of magnets.
- the coupling surface 90 of a magnetic coupler 62 may be defined at least in part by the shape and configuration of the housing, or body, 70 of the magnetic coupler.
- the housing of the magnetic couplers may be sized and/or shaped to include smooth complementary engagement surfaces in the coupling regions to contribute to the strength of the magnetic coupling between the coupling members at the coupling surfaces.
- These complementary engagement surfaces also may assist in the coupling regions being drawn and/or guided into proper alignment with each other and/or may reduce the ability of undesired external forces causing the coupling regions to uncouple from each other.
- the coupling surfaces may be shaped and/or sized, and/or may be bounded by ribs or projections or guides that facilitate alignment and retention of the coupling regions in a coupled configuration.
- the composition and/or thickness of the body may assist in defining the coupling surface. For example, exposing or only thinly covering the magnets or magnetic material at the coupling surface may increase the strength of the magnetic coupling between corresponding coupling surfaces 90. Similarly, increasing the thickness of regions of the body that are not intended to be the coupling surface (e.g., the thickness of material separating the magnetic coupler's magnets or magnetic material from the exterior of the body) may reduce the magnetic field that passes through those regions.
- the magnetic coupler body 70 may at least partially shield the external environment from magnetic fields of magnet(s) 72 of the magnetic footwear fastener' s magnetic couplers. At the coupling surface 90, the magnetic field may be enhanced, concentrated, and/or attenuated to achieve sufficient coupling between mating magnetic couplers 62.
- Bodies 70 may include, and/or may be, environmental-resistant and/or mechanically robust components such as coatings, coverings, fabric, polymeric materials, plastic, epoxy, rubber, and the like. Bodies also optionally may include, and/or may be, magnetic shielding components such as high magnetic permeability materials, ferromagnetic materials, and the like.
- Magnetic footwear fasteners 60, and/or one or both magnetic couplers 62 thereof may include mating features that are configured to guide and/or to align the magnetic couplers to a particular orientation and/or position when the magnetic couplers are drawn together to a coupled configuration.
- the mating features, when present, additionally or alternatively may be configured to interlock and/or to resist forces that may separate the magnetic assembly, i.e., to provide increased resistance to forces in a particular direction, relative to the resistance in the absence of the mating feature.
- mating features may provide resistance to shear forces, which are perpendicular to the orientation of the magnetic pole(s) of the magnet(s).
- Examples of configurations for magnetic couplers with mating features include the stud and cavity of a magnetic snap, one or more ridges, grooves, slots, tabs, flanges, studs, protrusions, recesses, cavities, and/or holes configured to mate with corresponding structures on mating magnetic couplers.
- Each magnetic coupler 62 of a magnetic footwear fastener 60 also includes a mechanical coupling region 92 that is configured to mechanically couple or otherwise physically connect the magnetic coupler to footwear 10.
- This mechanical, or physical, connection may be in a temporary or permanent manner, such as depending upon whether the magnetic footwear fastener is configured to be utilized as a magnetic footwear accessory that is not integrated into the construction of the footwear, or whether the magnetic footwear fastener is at least partially or completely integrated into the construction of the footwear.
- each magnetic coupler 62 may include at least one coupler eyelet 94.
- the footwear' s lace may be laced through the coupler eyelets and the footwear's footwear eyelets to couple the magnetic footwear fastener to the footwear and thereby permit selective use of the magnetic footwear fastener to retain the footwear in a closed, or sized, configuration around a wearer' s foot when the footwear is worn.
- the magnetic accessories permit selective release of the footwear to an open, or loosened, configuration without requiring untying or other manipulation of the lace.
- the footwear's foot opening may be enlarged to permit ready removal of the wearer' s foot from the footwear's foot compartment.
- recoupling the magnetic couplers together returns the footwear to the previously selected sized configuration, without requiring retying or other manipulation of the footwear' s lace.
- the mechanical coupling region 92 of the magnetic couplers is constructed and/or shaped to be secured to the shell, tongue, or other portion of the footwear' s upper in such a manner that it cannot be removed from the footwear without destruction or damage to at least a portion of the footwear, the mechanical coupling region, or any fastener mechanism that is utilized to provide this securement.
- the mechanical coupling region 92 may be a portion of the magnetic coupler that is sized, shaped, and/or constructed to be sewn, riveted, glued, laminated, or otherwise fastened to the footwear's shell, tongue, cap, or other upper portion.
- a mechanical coupling region 92 of an integrated magnetic coupler thus may include one or more coupler eyelets 94 or similar apertures that receive a lace, band, rivet, or other fastener that is not designed to be removed or to release the magnetic coupler without damage to the fastener, footwear, or magnetic coupler.
- the mechanical coupling region 92 may be sufficiently thin and/or formed of a suitable material to permit the mechanical coupling region to be sewn into the upper portion of the footwear.
- This thin, sewable portion of the mechanical coupling region 92 may be referred to as a fastening layer 212 and optionally may extend from, or be a portion of, the magnetic coupler's body 70 that is generally opposite/distal the magnetic coupling surface 90 of the magnetic coupler.
- the mechanical coupling region may be or include an adhesion layer, or adhesion surface, 211 that is shaped and/or constructed to be adhered, laminated, or otherwise bonded to an upper portion of the footwear.
- the above-discussed fastening layer 212 additionally or alternatively may be an adhesion layer 211, although it also is within the scope of the present disclosure that an adhesion layer, or adhesion surface, 211 may not be sewn, stitched, or otherwise suitable for being sewn or stitched to the footwear.
- an adhesion layer, or adhesion surface, 211 may not be sewn, stitched, or otherwise suitable for being sewn or stitched to the footwear.

- mechanical coupling region 92 may include, or be connected with other portions of body 70 by, a hinge, or pivot, 217.
- Elastic region 213, when present, may be configured to a portion of the magnetic coupler 62 and/or a corresponding portion of the footwear' s vamp portion, tongue, or other upper portion to stretch to accommodate the particular size of the wearer's foot that is inserted into the footwear's foot compartment without interfering with the fastening of the magnetic couplers of the magnetic footwear fastener.
- Biasing mechanism 214 when present, may be configured to urge one or both magnetic couplers of a magnetic footwear fastener to, and/or to remain in, a particular configuration or orientation, such as to be biased to or toward a coupled configuration or an uncoupled configuration.

- Magnets 72 may be oriented with their magnetic poles in any direction relative to the coupling surfaces 90 and/or the magnetic coupler body 70 without departing from the scope of the present disclosure. In some embodiments, it may be useful to orient the poles perpendicular to the length (longest dimension) of magnetic coupling surface 90, as doing so may increase the magnetic (attractive) force that retains the magnetic coupling surfaces 90 of a pair of magnetic couplers 62 together.

- Backing 82 when present, may support the magnet(s) and/or metallic material within the magnetic coupler's body, assist in the placement of the magnet(s) and/or metallic material, and/or assist in the assembly of the magnetic couplers.
- Backing 82 when present, may be formed from a ferromagnetic or non-ferromagnetic material. When formed from a ferromagnetic material, such as a ferromagnetic metallic material, this optional metal backing may serve to direct the magnetic forces of the magnet in the direction of the opposed magnet in an opposed magnetic coupler. When backing 82 is formed from a ferromagnetic material, it may be referred to as a ferromagnetic backing 82, a metallic backing 82, and/or a ferromagnetic metal backing 82.

- the magnetic couplers 62 of each magnetic footwear fastener 60 are aligned and operatively (magnetically) coupled together, for example, to generally support a wearer's foot within foot compartment 24 and to restrict a wearer's foot from being unintentionally removed from the foot compartment.
- the coupled configuration additionally or alternatively may be described as a configuration in which the magnetic couplers 62 define the size of, and/or restrict the size of, the footwear' s foot opening 32 and/or restrict enlargement of foot compartment 24, such as by preventing portions of the shell on opposed sides of channel 34 from moving away from each other.
- the footwear may be described as having a sized foot compartment and a sized foot opening.
- the foot opening and the foot compartment each may be described as having a coupled size, with the size of the foot opening and the foot compartment typically being enlarged when the footwear is in the uncoupled configuration, such as after a wearer removes the wearer' s foot from the foot compartment.
- footwear 10 when footwear 10 is in the coupled configuration with a wearer's foot within foot compartment 24, the footwear may be secured around the wearer's foot to provide the support and stability that traditionally would be provided when conventional laces or other fastening mechanisms are utilized and operatively secured.
- a wearer In the coupled configuration, a wearer may not be able to remove the wearer's foot from the footwear's foot compartment, or at least removal of the wearer's foot may be restricted or inhibited due to the magnetic couplers preventing the foot opening and/or foot compartment from enlarging.

- the footwear may be transitioned to the uncoupled configuration of Fig. 15, in which tongue 36 is moved away from foot opening 32.
- tongue 36 extends at least partially through a portion of channel 34 through which the tongue does not extend in the coupled configuration, and the foot opening and foot compartment are larger than in Fig. 13.
- the open configuration of Fig. 15 may be achieved in a variety of ways, as discussed herein, including by flexing of a wearer' s foot that is within the foot compartment and subsequent removal of the foot from the foot compartment.
- the uncoupled configuration of Fig. 15 also may be a useful configuration in which to leave footwear 10 after removal from a wearer's foot, as the enlarged foot opening and foot compartment may facilitate easier (re)insertion of the wearer's foot into the foot compartment when the wearer next wants to wear the footwear.
- tongue 36 may be returned to the position shown in Fig. 14, if necessary, and then the magnetic couplers may be returned to their coupled configuration. Doing so also returns footwear 10 to its coupled configuration. Because of the attraction between the magnetic coupling surfaces of the magnetic couplers, it may not be necessary for the wearer to position the magnetic coupling surfaces into contact with each other. Instead, moving the magnetic coupling surfaces near each other may be sufficient, with the magnetic attraction between the magnetic coupling surfaces causing the surfaces to be drawn into contact with each other.
- the footwear When the footwear includes more than one magnetic footwear fastener, the footwear optionally may be described as being in the uncoupled configuration at least when the coupling assembly closest to the foot opening is uncoupled.
- footwear 10 When footwear 10 includes two or more magnetic footwear fasteners 60 and at least one of the magnetic footwear fasteners is in an uncoupled configuration, the footwear optionally may be described as being in a partially uncoupled configuration.
- the uncoupled configuration additionally may be described as having a first subconfiguration and a second subconfiguration.
- the tongue 36 is within the foot compartment 24 and beneath the open channel 34.
- the tongue extends through the channel within the midfoot region of the footwear so that a wearer' s foot is generally less restricted from being removed from the shell than when the footwear is in the first subconfiguration.
- the foot opening 32 is larger than in the first subconfiguration shown in Fig. 14 and/or in the coupled configuration shown in Fig. 13.
- a wearer may remove the wearer' s foot from footwear 12 by flexing, such as plantar flexing, the wearer' s foot so that the wearer's foot causes the magnetic couplers 62 to become uncoupled and the tongue to extend up through the open channel.
- Fig. 14 illustrates that footwear 10 according to the present disclosure may include a tongue 36 that includes a tongue guide 54 that underlies the magnetic couplers 62 of a magnetic footwear fastener 60 when the magnetic couplers are magnetically coupled together to secure the footwear in a coupled configuration.
- Tongue guide 54 thus restricts the fabric or other material of the footwear's tongue from being pinched between the magnetic coupling surfaces 90 of the magnetic couplers and also provides a support, or guide, surface against which the magnetic couplers may be supported and/or slid as the magnetic coupling surfaces are drawn together.
- suitable tongue guides 54 include a stiffened and/or taut tongue region 56 on the tongue's surface that abuts the magnetic footwear fastener when the fastener is in a coupled configuration.
- the corresponding portion of the tongue may include a plastic or rubber coating or patch, a cured stiffener, etc.
- Fig. 14 also illustrates a less schematic example of footwear 10, such as laced footwear 12, that includes more than one magnetic footwear fastener 60, such as more than one magnetic accessory 64.
- magnetic footwear fasteners 60 may have a variety of shapes and sizes
- the magnetic couplers 62 of the magnetic accessory 64 closest to the foot opening each includes three coupler eyelets 94
- the magnetic couplers of the magnetic accessory closest to forefoot region 26 of the footwear each includes two coupler eyelets.
- the same size/style of magnetic accessories may be used instead of using two different sizes/styles.
- lace 46 may be interwoven through any opposing pair or pairs of footwear eyelets that are going to be directly connected by the lace.
- the lace may be interwoven through the footwear eyelets that are not utilized to secure the magnetic accessory to the footwear.
- the pair or pairs of footwear eyelets will be closest to the forefoot region of the footwear.
- left and right end regions of the lace are interwoven between respective left and right sets of footwear and coupler eyelets.
- footwear 12 may resemble the footwear shown in Fig. 13, except that the ends of the lace may still be restrained from passing through the footwear eyelets closest to the foot opening.
- the end regions of the lace may be much longer than necessary to complete the installation of the magnetic accessory.
- a wearer's foot may be inserted into the foot compartment, and the magnetic accessory may be configured to be in its coupled configuration.
- the lace Before securing the ends of the lace to define the size of the foot compartment and foot opening in the closed configuration of the footwear, the lace may be adjusted until the desired size/fit is achieved. After doing so, the ends of the lace may be secured so that they are restrained from being withdrawn through the utilized footwear eyelets that are closest to the foot compartment. As discussed, this may be accomplished by a variety of mechanisms, including knotting the end of the lace and/or securing the end of the lace with a lace retainer. Any excess length of the end regions of the lace may be cut off, or any excess length may be tucked within the foot compartment.
- the lace When cutting off the excess length of the end region of the lace, some excess length, such as 1-5 centimeters, may be retained to permit readjustment of the size of the foot opening and the foot compartment when the footwear is in the coupled configuration.
- the preceding method may still apply.
- the lace may be interwoven sequentially through all of the magnetic accessories, and all of the magnetic accessories should be in a coupled configuration before sizing the lace, and thereby defining the size of the foot compartment and foot opening when the footwear is in the coupled configuration.
- a single lace 46 When a single lace 46 is used to couple the magnetic couplers 62 of one or more magnetic accessories to an article of footwear 10, the lace typically will span channel 34 and/or directly lace at least one pair of left and right footwear eyelets.
- a pair of laces 46 may be used (one lace for the left series of footwear eyelets and the corresponding left magnetic coupler(s), and one lace for the right series of footwear eyelets and the corresponding right magnetic coupler(s)).
- the footwear' s lace 46 may be cut into two lace segments prior to installing the magnetic couplers, with one lace segment being use for the left series of footwear eyelets and the corresponding left magnetic coupler(s), and one lace segment being used for the right series of footwear eyelets and the right magnetic coupler(s).
- Magnetic footwear fasteners 60 in the form of magnetic accessories 64 may be sold with conventional laced footwear. Additionally or alternatively, magnetic accessories 64 may be packaged and/or sold as a kit, which is indicated schematically in dashed lines in Fig. 2 at 150. Kit 150 typically includes at least a pair of magnetic accessories 64, and kit 150 also may include instructions 152.

- magnetic footwear fasteners 60 are not required to always be magnetic accessories 64 that are selectively and removably utilized with footwear 10, including laced footwear 12. Such embodiments offer the advantage of being able to be utilized with conventional laced footwear, but this is not required to all embodiments.
- magnetic footwear fasteners 60 may include magnetic couplers 62 that are partially or completely integrated with footwear 10.
- the magnetic couplers additionally or alternatively may be described as not being removable from the footwear without damage or destruction of at least one of the footwear, the magnetic coupler, or any structure or device that secures the magnetic coupler to the footwear.
- Fig. 16 illustrates an example of footwear 10 with a magnetic footwear fastener 60 in the form of an integrated magnetic footwear fastener 66.
- both magnetic couplers 62 of the magnetic footwear fastener are integrated into the footwear' s upper 22, such as into the vamp portion 37 thereof on opposed sides of channel 34.
- magnetic footwear fasteners 60 and footwear 10 are illustrated in simplified forms in view of the considerable discussion about each of these components, optional features, variants, constructions, and the like in the preceding discussion and Figures.
- the illustrated fasteners 60 and footwear 10 should not be not limited to the simplified forms illustrated in Figs. 16-24 and instead may include any of the structures, features, components, variants, and the like discussed and/or illustrated elsewhere herein, such as in connection with Figs. 1-12.
- bands 160 are used to interconnect corresponding footwear eyelets 38 and coupler eyelets 94.
- Bands 160 are designed to permanently interconnect the footwear eyelets and coupler eyelets, and thus magnetic couplers 62 may not be removed from the footwear without damaging at least one of the bands, the magnetic couplers, or footwear 10.
- Examples of bands 160 include "zip tie" type bands that are not configured to be loosened or removed after being secured in a closed loop.
- Another example is a band that is clipped, fused, adhered, or otherwise fixed in a defined size and closed-loop configuration in which the band passes through adjacent footwear and coupler eyelets.
- Fig. 16 may be described as providing a further example of a magnetic accessory 64 because the magnetic couplers 62 may be removed and/or replaced without damage or destruction.
- the magnetic footwear fastener may be described as being an example of a partially integrated magnetic footwear fastener because one of the magnetic couplers may be selectively removed and replaced without damage to the coupler, footwear, or corresponding bands.
- the relative position of the removable magnetic coupler may be adjusted to adjust the size of the foot compartment and/or foot opening when the footwear is in a coupled configuration.
- Fig. 17 provides another example of footwear 10 with a magnetic footwear fastener 60 in the form of a partially integrated magnetic footwear fastener 68.
- the right magnetic coupler is integrated into the right series 44 of footwear eyelets 38 with bands 160, whereas the left magnetic coupler is removably (and thus adjustably) coupled to the left series 42 of footwear eyelets 38 by lace 46.
- Figs. 16 and 17 illustrate footwear 10 in which the footwear includes a plurality of footwear eyelets 38 on each side of the footwear' s channel 34.
- the footwear of Figs. 16 and 17 still may be described as being laced footwear 12, in that the footwear eyelets permit conventional use of a lace to size the footwear' s foot compartment and foot opening, such as prior to installation of the magnetic footwear fastener or if the magnetic footwear fastener is removed from the footwear.
- footwear 10 may not include footwear eyelets and/or may not utilize a lace for selective sizing of the foot compartment.
- footwear 10 that includes a magnetic footwear fastener 60 in the form of an integrated magnetic footwear fastener 66 and that does not include footwear eyelets or a lace is shown in Fig. 18 and generally indicated 200.
- the footwear's upper 22 includes a channel 34 in the form of a narrow opening defined between the edges 35 of opposed vamp portions 37 of the footwear' s upper 22.
- the integrated magnetic footwear fastener' s magnetic couplers 62 are integrated into vamp portions 37 on opposed sides of channel 35. Edges 35 may face each other when the magnetic footwear fastener is in the coupled configuration and may face generally away from each other when the magnetic footwear fastener is in an uncoupled configuration.
- each magnetic coupler 62 includes a magnetic coupling region 88 with a magnetic coupling surface 90 that generally faces the corresponding magnetic coupling region and magnetic coupling surface of the other magnetic coupler when the magnetic footwear fastener is in the coupled configuration shown in Fig. 18.
- Upper 22 and/or vamp portions 37 additionally or alternatively may be described as including flaps 37 with edges 35 that are positioned together or in close proximity when the magnetic footwear fastener is in a coupled configuration and which are spaced apart from each other (to a greater relative extent) when the magnetic footwear fastener is in an uncoupled configuration.
- the flaps and/or vamp portions 37 may be formed of conventional materials from which footwear uppers are formed, including fabric or leather. It also is within the scope of the present disclosure that the flaps and/or vamp portions 37 may be formed from, and/or include a subregion that is formed from, an elastic or otherwise resiliently stretchable material. Including such a stretchable region may enable the flaps and/or vamp portions to adjust their relative size and orientation to adjust to the shape and/or size of the wearer's foot that is received into the footwear's foot compartment 24.
- the magnetic coupling regions 88 are shown extending generally along the corresponding edges 35 of the vamp portions 37 to which the magnetic couplers 62 are integrated. It is within the scope of the present disclosure that the magnetic coupling regions 88 alternatively are configured to be recessed slightly from or extend beyond/over the edges of the vamp portions to which the magnetic couplers are integrated.
- the magnetic couplers 62 are shown in Fig. 18 as being beneath the exterior, or outer surface, of the vamp portions 37 to which the magnetic couplers are integrated. It is within the scope of the present disclosure that the magnetic couplers may be secured on top of the vamp portions, secured beneath the vamp portions, or embedded or otherwise positioned within the vamp portions.
- integrated magnetic couplers also include a mechanical coupling region 92 that is configured to mechanically couple or otherwise physically connect the magnetic coupler to the footwear, such as to the vamp portion 37 to which the coupler is integrated.
- mechanical coupling region 92 takes the form of a fastening layer 212 that projects from body 70 of the magnetic coupler along and/or with vamp portion 37 of the footwear's upper.
- Fastening layer 212 may be integrated into the vamp portion by any suitable mechanism, such as by sewing, riveting, adhering, fusing, or otherwise securing the fastening layer 212 in such a manner that the magnetic coupler is securely integrated to the vamp portion.
- fastening layer 212 additionally or alternatively may be referred to as an adhesion layer 211.
- Fastening layer 212 additionally or alternatively may be and/or include an elastic region 213 and/or a stiffened region 215.
- An elastic region 213, when present, may be configured to permit the vamp portion 37 of the footwear' s upper to which the magnetic coupler is integrated to stretch to accommodate the particular size of the wearer' s foot that is inserted into the footwear's foot compartment without interfering with the fastening of the magnetic coupler to the vamp portion. This may increase the fit and/or comfort of the footwear and also may reduce forces that may urge the magnetic footwear fastener to unintentionally uncouple, such as if the wearer' s foot is sufficiently large that the magnetic coupling surfaces of the magnetic couplers may not be fully engaged in the coupled configuration.
- Elastic region 213 additionally or alternatively may be referred to as a resiliently stretchable region 213 and/or a resilient region 213.
- Stiffened region 215, when present, may provide a further example of an anti-pinch mechanism and/or guide mechanism that facilitate(s) urging of the magnetic couplers to a coupled configuration.
- an integrated magnetic coupler may include a mechanical coupling region 92 that does not include a fastening layer 212.
- body 70 itself may form the mechanical coupling region, in that the body is adhered, riveted, fastened, fused, or otherwise integrated into the footwear' s upper, such as vamp portions 37 thereof.
- the mechanical coupling region 92 may be one or more discrete extensions or projections of the body 70, such as to receive stitching or a mechanical fastener to integrate the magnetic coupler to the footwear' s upper.
- one or more coupler eyelets or similar apertures may be formed in or extend from the coupler' s body to receive a tie, integrated lace, tether, rivet, or other mechanical fastener to secure the mechanical coupling region to the footwear.
- Fig. 18 also schematically illustrates that the mechanical coupling region 92 of a magnetic coupler 62 may include a hinge, or pivot, 217 that pivo tally couples the mechanical coupling region to the footwear and/or that pivo tally couples portions of the magnetic coupler together for relative pivotal movement.
- a hinge 217 may pivotally interconnect mechanical coupling region 92 with the portion of body 70 that contains magnetic coupling surface 90 of the magnetic coupler.
- Such a construction may permit repeated flexing or pivoting of the portion of the magnetic coupler that contains the magnetic coupling surface relative to the mechanical coupling region 92 and/or the portion of the footwear' s upper to which the mechanical coupling region is coupled. Any suitable mechanical construction may be utilized for hinge 217.
- footwear 200 of Fig. 18 is shown in an uncoupled configuration.
- Footwear 200 may be configured to the uncoupled configuration through any of the methods described herein, such as by flexing of the wearer's foot and/or manual separation of the magnetic couplers by the wearer' s hands.
- the magnetic coupling surfaces 90 of the magnetic couplers are spaced apart from each other relative to their position in the coupled configuration of Fig. 18.
- foot compartment 24 and foot opening 32 are larger in the uncoupled configuration of Fig. 19 than in the coupled configuration of Fig. 18, in which the integrated magnetic footwear fastener restricts enlargement of the foot compartment and the foot opening.
- Fig. 19 also illustrates that footwear 10, including footwear 200, may include a biasing mechanism 214 that is configured to urge the magnetic footwear fastener to, and/or to remain in, an uncoupled configuration.
- biasing mechanism 214 may exert a biasing force that urges the magnetic coupling surfaces 90 of the magnetic couplers away from each other, such as to urge the magnetic couplers and/or corresponding vamp portions of upper 22 to pivot, curl, fold, or otherwise move away from each other.
- This biasing force exerted by the biasing mechanism should be less than the magnetic force that retains the magnetic coupling surfaces together when the magnetic footwear fastener is in a coupled configuration.
- biasing mechanism 214 may reduce the force that the wearer otherwise needs to apply to intentionally uncouple the magnetic footwear fastener.
- biasing mechanism 214 when present, may urge the magnetic coupling surfaces 90 of the magnetic couplers 62 to remain separated from each other when the magnetic footwear fastener is in an uncoupled configuration.
- the magnetic couplers may be designed so that their magnetic coupling surfaces are strongly (magnetically) attracted to each other, but only when placed close to each other due to the magnetic field being concentrated to the magnetic coupling surface.
- Biasing mechanism 214 when present, may urge the uncoupled magnetic couplers to remain a greater distance apart from each other than the minimum distance in which magnetic coupling surfaces will be drawn, by the exerted magnetic field, into contact with each other.
- Biasing mechanism 214 additionally or alternatively may be referred to as biasing structure 214 and may take any suitable form and/or may include any suitable structure.
- biasing mechanism 214 may be or include a bistable material, a leaf (or other) spring, and/or a resilient material having a neutral state in which the magnetic coupling surfaces are spaced apart and/or away from each other.
- Footwear 10, including footwear 200, that does not include a lace or straps to adjust the size of the foot compartment and/or foot opening of the footwear may include an upper-adjustment mechanism 216 that permits selective adjustment of the size of the footwear's foot compartment and/or foot opening.
- an upper-adjustment mechanism 216 that permits selective adjustment of the size of the footwear's foot compartment and/or foot opening.
- the upper-adjustment mechanism 216 when present, may provide this adjustability by any suitable mechanism and/or structure.
- the upper-adjustment mechanism 216 may permit selective adjustment within a range of user-selected positions, such as how a user conventionally may adjust the size of a foot compartment by adjusting the position of laces, straps, and similar structure.
- Upper-adjustment mechanism 216 additionally or alternatively may be referred to as a shell adjustment mechanism 216, a footwear sizing mechanism 216, an upper sizing mechanism 216, a shell sizing mechanism 216, an adjustment mechanism 216, and/or a sizing mechanism 216.
- an upper-adjustment mechanism 216 is the elastic region(s) described above with respect to Fig. 18.
- Fig. 20 also illustrates an optional upper-adjustment mechanism 216 in the form of at least one elastic region 213 of upper 22. As discussed, this elastic/stretchable region permits selective resilient stretching of the upper to accommodate different sizes of wearers' feet that may be inserted into the footwear' s foot compartment.
- Fig. 20 also provides an example of an upper-adjustment mechanism 216 in the form of a tether, or tie, mechanism 218 that selectively reduces the size of the footwear's foot compartment 24.
- tie mechanism 218 includes a series of adjustment eyelets 220 on both sides of region 213, and a tie 222 that extends through the adjustment eyelets 220.
- the adjustment eyelets 220 on opposing sides of region 213 are drawn closer together or are permitted to be farther apart from each other, thereby adjusting the size of the foot compartment.
- the length of tie 222 may be adjusted in any suitable manner, including those described herein in connection with adjusting the size of lace 46.
- region 213 may be an elastic region, such as discussed above, although it alternatively may simply be a non-elastic portion of the upper, such as which may be formed from leather, fabric, etc.
- upper-adjustment mechanism 216 include a series of hook-and-eye and/or hook-and-loop structures that selectively adjust the distance between the opposing sides of region 213.
- Fig. 20 also provides graphical, albeit somewhat schematic, examples of magnetic couplers 62 that are positioned above (i.e., on the exterior surface of) and/or below (i.e., within and/or underneath) the vamp portions 37 of the footwear' s upper to which the magnetic couplers are integrated.
- Figs. 21 and 22 provide further examples of footwear 10 in the form of footwear 200 with magnetic footwear fasteners 60 in the form of integrated magnetic footwear fasteners 66.
- Figs. 21 and 22 also provide further examples of footwear 10 and/or 200 in which the vamp regions 37 include an upper-adjustment mechanism 216 in the form of elastic region 213.
- the vamp regions 37 include and/or are formed from an elastic or otherwise resiliently stretchable material that enables the size of the foot compartment 24 to adjust to better conform to the size of the wearer's foot that is inserted into the foot compartment.
- the illustrated footwear additionally may include a biasing mechanism 214 to urge the magnetic coupling surfaces 90 of the integrated magnetic couplers away from their coupled configuration.
- Fig. 22 also provides an additional example of upper-adjustment mechanism 216 and/or lock mechanism 140.
- the footwear includes at least one strap 230 that is selectively fastened across channel 34 to selectively adjust the size of foot compartment 24 and/or restrict the magnetic coupling surfaces 90 of the magnetic fasteners 62 from separating and thereby transition from a coupled configuration to an uncoupled configuration.
- a series of spaced-apart straps 230 are shown in Fig. 22, but it is within the scope of the present disclosure that the number of such optional straps 230 may vary.
- Straps 230 may have any suitable form and/or may be formed from any suitable material, including elastic and nonelastic materials.
- One or both end regions 232 of each strap may be sewn or otherwise integrated into the upper, such as vamp portion 37. Additionally or alternatively, one or both end regions 232 of each strap may removably coupled to the upper, (such as vamp portion 37) by a releasable fastening mechanism. Examples of releasable fastening mechanisms are discussed herein and include hook-and-loop fasteners, hook-and-eye fasteners, snaps, and clips.
- the corresponding vamp portion 37 or other region of the upper may include a strap -receiver 234 that is configured to receive and selectively and temporarily retain the end region of the strap.
- one or both end regions of a strap 230 may include the hook or the loop portion of a hook-and-loop fastener, and the corresponding vamp region or other upper portion may include the other of the hook or the loop portion of a hook-and-loop fastener.
- snap fasteners and/or hook-and-eye fasteners may be utilized in a similar manner.
- Figs. 23 and 24 illustrate additional examples of footwear 10 with magnetic footwear fasteners 60 in the form of integrated magnetic footwear fasteners 66.
- Figs. 23 and 24 illustrate examples of footwear 10 in which a pair of magnetic fastening mechanisms 60 are utilized to configure the footwear into its coupled configuration, with each magnetic fastening mechanism 60 including one magnetic coupler 62 that is integrated with the footwear' s vamp portion 37 and one magnetic coupler 62 that is integrated with the footwear' s tongue 36.
- the left and right sides (which also may be referred to as the lateral and medial sides) of the footwear' s tongue each are magnetically coupled to a corresponding left and right (or lateral and medial) vamp portion when the footwear is in its coupled configuration, such as shown in Fig. 23.
- the portion of tongue 36 to which magnetic couplers 62 are integrated proximal the footwear's foot opening 32 extends above vamp portions 37.
- This portion is generally indicated in Figs. 23 and 24 at 240.
- a tongue, or tongue portion that extends above the vamp portion and corresponding channel 34 when the magnetic footwear fastener is in the coupled configuration additionally or alternatively may be referred to as a cap, or cover.
- the magnetic couplers 62 on the tongue may be positioned in any suitable location of the tongue to operatively (magnetically) couple to the corresponding magnetic couplers 62 on the footwear' s vamp portions to selectively secure the footwear in its coupled configuration.
- the magnetic coupling surface of the magnetic couplers 62 on the tongue may be on or extend from an underside of tongue portion 240. In some embodiments, the magnetic coupling surface of the magnetic couplers 62 on the tongue may be on and/or extend from a side (lateral or medial) of the tongue. In some embodiments, the magnetic couplers on the tongue may be integrated within the tongue and thus may be generally hidden from view and protected from external elements, regardless of whether the footwear is in a coupled configuration or an uncoupled configuration.
- Fig. 23 When the footwear of Fig. 23 is urged to its uncoupled configuration, such as is shown somewhat schematically in Fig. 24, it can be seen that the corresponding portion of tongue (or cap) 240 into which the magnetic couplers 62 are integrated may bend, pivot, or otherwise move away from the foot compartment. For example, flexing of the wearer's foot from within the foot compartment may exert sufficient force on the tongue and corresponding magnetic footwear fasteners to cause the magnetic coupling surfaces 90 of the fasteners to separate and permit the pivotal or similar movement of the tongue portion away from the foot compartment.
- At least portion 240 of tongue 36 may be stiff, or at least stiffer than the material that forms the upper portion of the shell.
- Portion 240 optionally may include a rigid, or semi-rigid, insert to stiffen the tongue portion.
- portion 240 and/or 244 of tongue 36 optionally may include a stiffened region 215, as indicated in Fig. 24.
- footwear 10 and magnetic footwear fasteners 60 may have a variety of features, components, variants, etc. It also has been discussed that features, components, variants, etc. that are introduced and/or illustrated with respect to one or more examples may be used with other examples without departing from the scope of the present disclosure. Figs. 23 and 24 thus include additional examples of such features, components, and/or variants, which accordingly are not going to be discussed again.
- Fig. 23 illustrates another example of an upper-adjustment mechanism 216, with the depicted example including a plurality of tongue eyelets 242 through which a lace 46 is interwoven.
- the size of the footwear' s foot compartment 24 may be selectively adjusted by tightening or loosening the tension in lace 46, as doing so adjusts the relative distance between the tongue eyelets 242 on the left and right (lateral and medial) sides of the tongue.
- this relative adjustment of the distance between the tongue eyelets results in a selective adjustment of the width of the tongue and thereby an adjustment of the foot compartment' s size.
- tongue eyelets 242 are shown in Fig. 23 on the upper/exterior surface of the tongue, it is within the scope of the present disclosure that the tongue eyelets alternatively may be on the underside (which faces foot compartment 24) of the tongue or that the tongue eyelets may be formed within the tongue and thereby not visible from external the tongue. In either of these optional configurations, at least a portion of the lace that is interwoven through the tongue eyelets may still be accessible from external the tongue to permit a wearer to selectively tighten or loosen the tension in the lace and thereby adjust the relative size of the tongue and the foot compartment.
- Fig. 23 also illustrates that an additional pair of magnetic footwear fasteners 60 may be utilized to magnetically couple a second portion 244 of the tongue to the footwear' s upper.
- the second portion of tongue 36 is indicated generally in dashed lines at 244 and may be described as being closer to the forefoot region 26 of the footwear' s upper than tongue portion 240.
- the second portion 244 of the tongue optionally also may extend above channel 34 when the footwear is in its coupled configuration.
- Portion 244 of tongue 36 may be directly secured to the forefoot region of the footwear, as discussed herein; however, it also is within the scope of the present disclosure that a removable fastening mechanism, such as a snap, button, hook-and-loop fastener, and the like may be utilized to connect the tongue to the forefoot region of the footwear.
- a removable fastening mechanism such as a snap, button, hook-and-loop fastener, and the like may be utilized to connect the tongue to the forefoot region of the footwear.
- Fig. 24 also illustrates further examples of a biasing mechanism 214 that may be selectively included to urge/retain the magnetic couplers away from their coupled configuration.
- the biasing mechanism 214 is illustrated as biasing the tongue portion(s) away from channel 34, and thereby urging the magnetic couplers that are integrated into the tongue portion(s) away from the corresponding magnetic couplers that are integrated into the footwear' s upper, such as the vamp portions thereof.
- the footwear may include a guide mechanism 130 that is configured to retain the corresponding magnetic couplers 62 of a magnetic footwear fastener 60 in sufficient alignment that the corresponding magnetic coupling surfaces of the magnetic couplers will be positioned sufficiently close to each other to be magnetically coupled in the coupled configuration when the tongue is pivoted back toward the footwear compartment.
- At least tongue portion 240 may be biased, or predisposed, to automatically pivot away from the footwear' s foot compartment 2.
- Such a construction may facilitate a wearer inserting the wearer' s foot into the footwear' s foot compartment to don the footwear, and in some embodiments, removal of the wearer' s foot from the foot compartment.
- the biasing of at least tongue portion 240 to, and/or to remain in, the uncoupled configuration may make it easier for the wearer to insert the wearer' s foot into the foot compartment due to the comparatively larger foot opening 32 that is provided to the wearer.
- the wearer may urge tongue portion 240 to return toward the foot compartment, such as against the bias of biasing mechanism 214.
- guide mechanism 130 may urge or retain the magnetic couplers of each magnetic footwear fastener to remain sufficiently aligned. As the corresponding magnetic coupling surfaces of each corresponding pair of magnetic couplers are positioned near each other, the magnetic attraction between the surfaces should urge the surfaces to move together to configure the magnetic footwear fasteners, and thus the footwear, back to the coupled configuration.
- the terms “adapted” and “configured” mean that the element, component, or other subject matter is designed and/or intended to perform a given function. Thus, the use of the terms “adapted” and “configured” should not be construed to mean that a given element, component, or other subject matter is simply "capable of performing a given function but that the element, component, and/or other subject matter is specifically selected, created, implemented, utilized, programmed, and/or designed for the purpose of performing the function. It also is within the scope of the present disclosure that elements, components, and/or other recited subject matter that is recited as being adapted to perform a particular function may additionally or alternatively be described as being configured to perform that function, and vice versa. Similarly, subject matter that is recited as being configured to perform a particular function may additionally or alternatively be described as being operative to perform that function.
- the term "and/or" placed between a first entity and a second entity means one of (1) the first entity, (2) the second entity, and (3) the first entity and the second entity.
