Abstract
Tread cradles for covering a sole of an article of footwear having at least one cleat are described, the tread cradles comprising bases having first and second sides, treads disposed on the first side of the bases, and disposed on the second side of the base, means for reversibly securing the cleat to the base, thereby removably attaching the article of footwear to the tread cradle. Covering the sole prevents mud, grass, and other debris from sloughing off, protects the sole from abrasive surfaces, such as concrete and asphalt, protects flooring surfaces, and may cushion the article of footwear for greater user comfort.
Description
- This application is claims the benefit of U.S. Provisional Application No. 61/923,876 filed Jan. 6, 2014, which is incorporated by reference in its entirety.
- Certain types of athletic footwear, particularly those with aggressive tread, such as soccer cleats and football cleats, tend to collect mud, grass, and other debris. If subsequently worn indoors, the mud, grass, and other debris slough off, leaving waffle-like clumps. Moreover, abrasive surfaces such as concrete and asphalt quickly wear down the aggressive tread, reducing their efficacy and eventually requiring replacement of the entire footwear article. Conversely, aggressive tread can damage or disfigure flooring surfaces, leading to scuffs, scratches, or digs.
- While these foregoing problems can be avoided by only wearing the footwear article on the field of play, in practice, this is usually inconvenient and at times impossible, such as for last minute field changes or other overlapping scheduling. Accordingly, what is needed is a device to prevent previously collected mud, grass, and other debris in the tread of athletic footwear from sloughing off while a user moves, and to protect the tread from contact with abrasive surfaces.
- Tread cradles for covering a sole of an article of footwear having at least one cleat are described, the tread cradles comprising bases having first and second sides, treads disposed on the first side of the bases, and disposed on the second side of the base, means for reversibly securing the cleat to the base, thereby removably attaching the article of footwear to the tread cradle.
- Methods for covering a sole of an article of footwear having at least one cleat are described, the method comprising providing a tread cradle having a base and means for reversibly securing the cleat to the base, thereby removably attaching the article of footwear to the tread cradle.
- Methods for manufacturing a tread cradle for covering a sole of an article of footwear having at least one cleat are described, the methods comprising determining the position of the at least one cleat on the footwear, and providing a receptacle on the tread cradle in a position corresponding to the position of the at least one cleat on the footwear, the receptacle being capable of reversibly securing the cleat in the receptacle, thereby removably attaching the article of footwear to the tread cradle.

FIG. 1 is a perspective view of an article ofathletic footwear 100. Thefootwear 100 may be designed for a specific sport, such as for soccer, American football, or baseball. Thefootwear 100 comprises an upper 102, the upper having aheel region 102 a, amiddle region 102 b, and atoe region 102 c. The upper 102 may be of materials that are man-made or natural, or a combination thereof. Atongue 104 andlaces 106 are disposed in the upper 102 in order to provide a secure fit for a user's foot (not depicted). - The
footwear 100 comprises a sole 108 connected to the upper 102. The sole 108 hascleats 110, which provide an aggressive tread for playing field surfaces, and may have various patterns, including studs and/or blades, as will be described with reference toFIGS. 5 a-5 d. Thefootwear 100 may have a lining, an insole, and a midsole disposed between the upper 102 and the sole 108, although such features are not depicted for simplicity of illustration. - Turning to
FIG. 2 , atread cradle 200 is removeably attached to thefootwear 100 to form anassembly 210. Thefootwear 100 may be a conventional athletic shoe, or, alternatively, it may be an athletic shoe specially adapted to cooperate with thetread cradle 200 and sold together as anassembly 210 or a kit. - “Removeably attached” means that the
tread cradle 200 andfootwear 100 engage in a manner that is reversibly secure, in other words, capable of being repeatedly attached, separated, and reattached without undue effort or damage. Consistent with the understanding of those skilled in the art, removeably attached refers to being attached, separated, and reattached by the user of the footwear, and is not intended to be limited to steps taken during manufacture. Thetread cradle 200 has means (not depicted inFIG. 2 ) to engage thecleats 110 in a manner that allows the tread cradle to be removeably attached to thefootwear 100. - The
tread cradle 200 comprises abase 212. Thebase 212 may comprise polymer foams, ethylene and vinyl acetate (EVA), or polyurethane, or a combination thereof. Thebase 212 may provide support, used interchangeably herein with cushioning, such that the cushioning provided by the combination of thetread cradle 200 andfootwear 100 is greater than the cushioning provided by the footwear by itself. As such, this may be advantageous for athletes recovering from injury who require more cushioning during, for example, warm-ups, but who wish to be ready for play without having to change footwear. In yet another example, the base may provide the ability to convert the footwear from use on one surface to another (e.g., grass turf to artificial turf, grass turf to court) or from a sport specific tread to another sport specific tread (e.g., soccer to futsal, soccer to tennis, or soccer to basketball). -
Sidewalls 214 extend relatively upward from thebase 212. Thesidewall 214 has anarea 214 a that may comprise information, indicia of origin, decorative features, or structural features. Examples of information and/or indicia of origin include trademarks, logos, sport-specific representations (such as of a soccer ball), or a number (such as a shoe size). Examples of decorative and/or structural features include springs, viewing windows, and bladders. -
Treads 216 extend relatively downward from thebase 212. Thetreads 216 may comprise blown rubber or carbon rubber, or a combination thereof. Thetreads 216 may be solid, patterned, grooved, or otherwise adapted to confer fraction comparable to that provided by a running shoe. Thetread cradle 200 may be designed to look like the midsole and outsole of a running shoe. - Referring to
FIG. 3 , in the prior art, a previous method for preventing collected mud, grass, and other debris (not depicted) from sloughing from the tread ofathletic footwear 300 employed acover 302 that resembled clogs or galoshes. Thecover 302 engages the perimeter of thefootwear 300 to remain in place. - Referring to
FIG. 4 , in the prior art, a previous method for preventing collected mud, grass, and other debris (not depicted) from sloughing from the tread ofathletic footwear 400 employs acover 402 that resembles a hospital shoe cover. Thecover 402 engages the perimeter of thefootwear 400 to remain in place. - As mentioned with respect to
FIG. 2 , thetread cradle 200 has means to engage thecleats 110 in a manner that allows the tread cradle to be removeably attached to thefootwear 100. Such an approach is more complex than simple perimeter engagement discussed above. For example, turning toFIGS. 5 a-5 d, bottom plan views of articles ofathletic footwear large studs 510, small studs 520 (also known as nubs),blades 530, or a combination of studs and blades. Cleats may be molded integral to the footwear, or replaceable, such as by being engaged by threaded interaction (e.g., screwed in). As will be discussed, cleat engagement may be advantageously achieved by the present tread cradles by employing mirror image engagement (FIG. 6 ), reference point engagement (FIG. 10 ), or key engagement (FIG. 11 ). - Referring now to
FIG. 6 , an exploded perspective view of an assembly substantially similar to theassembly 210 ofFIG. 2 , and using the same reference numerals, is illustrated. Thefootwear 100, with upper 102,tongue 104,laces 106, sole 108, andcleats 110, removeably attaches to thetread cradle 200. Areceptacle 630 extends relatively upward from thebase 212 of thetread cradle 200. Thereceptacle 630 engages thecleat 110 in a manner that is reversibly secure. As mentioned above, thefootwear 100 may have various patterns, including studs and/or blades, as described with reference toFIGS. 5 a-5 d. As illustrated inFIG. 6 , the number and position ofreceptacles 630 may correspond to the number and position ofcleats 110 in substantially a mirror image. Also as illustrated inFIG. 6 , thecleats 110 are the large stud type. However, it will be appreciated that the embodiments described herein usingreceptacles 630 adapted to large stud cleats can be modified to accommodate a variety of patterns and cleat types. -
FIG. 7 is a cross sectional view through areceptacle 730, which may be an example of a receptacle 630 (FIG. 6 ). Thereceptacle 730 extends from abase 712 of the tread cradle (not depicted). Thereceptacle 730 compriseswalls 732 defining anopening 734. Alip 736 is disposed adjacent to theopening 734. Thelip 736 may be deformable and sufficiently elastic to allow a cleat (not depicted) to pass through theopening 734. Thelip 736 may stretch to surround the cleat (not depicted), thereby reversibly securing the cleat, and hence its attached footwear (not depicted), to the tread cradle (not depicted). - The
walls 732 further define areceptacle floor 738. Thereceptacle floor 738 may be the same material as thebase 712. Thereceptacle floor 738 may contribute no additional thickness to thebase 712, or the receptacle floor may make the base thicker (such as for additional cushioning), or the receptacle floor may retain an EVA insert (not depicted) for additional cushioning beyond that provided by the base. Although not depicted, thereceptacle floor 738 may be bored out, making the base 712 thinner, for a lower overall tread cradle profile. Thereceptacle floor 738 may be treated, for example with a pressure-sensitive adhesive, to help retain the cleat. It is understood that throughout this specification, “pressure-sensitive adhesive” is understood to be a composition for increasing the tack of coated surfaces, but not to permanently bond them. -
FIG. 8 is a cross sectional view through areceptacle 830, which may be an example of a receptacle 630 (FIG. 6 ). Thereceptacle 830 extends from abase 812 of the tread cradle (not depicted). Thereceptacle 830 compriseswalls 832 defining anopening 834. Alip 836 is disposed adjacent to theopening 834. Thelip 836 may be deformable and sufficiently elastic to allow a cleat (not depicted) to pass through theopening 834. Thelip 836 may stretch to surround the cleat (not depicted), thereby reversibly securing the cleat, and hence its attached footwear (not depicted), to the tread cradle (not depicted). - The
walls 832 further define areceptacle floor 838. Thereceptacle floor 838 may be the same material as thebase 812. Thereceptacle floor 838 may contribute no additional thickness to thebase 812, or the receptacle floor may make the base thicker (such as for additional cushioning), or the receptacle floor may retain an EVA insert (not depicted) for additional cushioning beyond that provided by the base. Although not depicted, thereceptacle floor 838 may be bored out, making the base 812 thinner, for a lower overall tread cradle profile. Thereceptacle floor 838 may be treated, for example with a pressure-sensitive adhesive, to help retain the cleat. - A
rib 840 extends from thewall 832 below thelip 836. Therib 840 is sufficiently elastic to allow a cleat (not depicted) to pass by, and the rib may stretch to surround the cleat, in addition to thelip 836, thereby reversibly securing the cleat, and hence its attached footwear (not depicted), to the tread cradle (not depicted). -
FIGS. 9 a & 9 b illustrate areceptacle 930, which may be an example of a receptacle 630 (FIG. 6 ). Thereceptacle 930 extends from abase 912 of the tread cradle (not depicted). Thereceptacle 930 compriseswalls 932 defining anopening 934. Thewalls 932 further define areceptacle floor 938. Thereceptacle floor 938 may be the same material as thebase 912. Thereceptacle floor 938 may contribute no additional thickness to thebase 912, or the receptacle floor may make the base thicker (such as for additional cushioning), or the receptacle floor may retain an EVA insert (not depicted) for additional cushioning beyond that provided by the base. Although not depicted, thereceptacle floor 938 may be bored out, making the base 912 thinner, for a lower overall tread cradle profile. Thereceptacle floor 938 may be treated, for example with a pressure-sensitive adhesive, to help retain the cleat. - A plurality of
splines 950 extend radially from thewall 932. Thesplines 950 may be deformable and sufficiently elastic to allow a cleat (not depicted) passing through theopening 934 to bend the splines around the cleat, thereby reversibly securing the cleat, and hence its attached footwear (not depicted), to the tread cradle (not depicted). Thesplines 950 may be treated, for example with a pressure-sensitive adhesive, to help retain the cleat. - Turning to
FIG. 10 , analternative tread cradle 1000 is illustrated. Thetread cradle 1000 comprises abase 1012. Thebase 1012 may comprise polymer foams, ethylene and vinyl acetate (EVA), or polyurethane, or a combination thereof. Thebase 1012 may provide cushioning, such that the cushioning provided by the combination of thetread cradle 1000 and footwear (not depicted) is greater than the cushioning provided by the footwear by itself. As such, this may be advantageous for athletes recovering from injury who require more cushioning during, for example, warm-ups, but who wish to be ready for play without having to change footwear. - The
base 1012 may have azone 1012 a. Thezone 1012 a may be of memory foam, EVA, or combination thereof. Thezone 1012 a may be treated with pressure-sensitive adhesive. Thezone 1012 a may provide additional reversible securing, such as by impressions in memory foam or the pressure-sensitive adhesive. Thezone 1012 a may provide additional cushioning, so that thetread cradle 1000 may be used for long runs. -
Sidewalls 1014 extend relatively upward from thebase 1012. Thesidewall 1014 has anarea 1014 a that may comprise information, indicia of origin, decorative features, or structural features. Examples of information and/or indicia of origin include trademarks, logos, sport-specific representations (such as of a soccer ball), or a number (such as a shoe size). Examples of decorative and/or structural features include springs, viewing windows, and bladders. -
Treads 1016 extend relatively downward from thebase 1012. Thetreads 1016 may comprise blown rubber or carbon rubber, or a combination thereof. Thetreads 1016 may be solid, patterned, grooved, or otherwise adapted to confer fraction comparable to that provided by a running shoe. Thetread cradle 1000 may be designed to look like the midsole and outsole of a running shoe. - A
receptacle 1030 extends relatively upward from thebase 1012 of thetread cradle 1000. Thereceptacle 1030 engages the cleat (not depicted) in a manner that is reversibly secure. As mentioned above, the footwear may have various patterns, including studs and/or blades, as described with reference toFIGS. 5 a-5 d. Thetread cradle 1000 need not have substantially a mirror image correlation between the number and position of receptacles and the number and position of cleats. Rather, the number and position ofreceptacles 1030 correspond to a subset of reference cleats in preselected positions, allowing the receptacles to engage the reference cleat (not depicted) in a manner that is reversibly secure. Cleats that do not have corresponding receptacles interact with thezone 1012 a. The reference cleats may be pre-selected based on mold continuities among certain brands, or mold continuities among certain sizes, or mold continuities due to process standardization. For example, inFIG. 10 , the reference cleats are in the toe and heel regions. - Turning to
FIG. 11 , an alternative tread cradle 1100 is illustrated. The tread cradle 1100 comprises abase 1112. Thebase 1112 may comprise polymer foams, ethylene and vinyl acetate (EVA), or polyurethane, or a combination thereof. Thebase 1112 may provide cushioning, such that the cushioning provided by the combination of the tread cradle 1100 and footwear (not depicted) is greater than the cushioning provided by the footwear by itself. As such, this may be advantageous for athletes recovering from injury who require more cushioning during, for example, warm-ups, but who wish to be ready for play without having to change footwear. - The
base 1112 may have azone 1112 a. Thezone 1112 a may be of memory foam, EVA, or combination thereof. Thezone 1112 a may be treated with pressure-sensitive adhesive. Thezone 1112 a may provide additional reversible securing, such as by impressions in memory foam or the pressure-sensitive adhesive. Thezone 1112 a may provide additional cushioning, so that the tread cradle 1100 may be used for long runs. -
Sidewalls 1114 extend relatively upward from thebase 1112. Thesidewall 1114 has anarea 1114 a that may comprise information, indicia of origin, decorative features, or structural features. Examples of information and/or indicia of origin include trademarks, logos, sport-specific representations (such as of a soccer ball), or a number (such as a shoe size). Examples of decorative and/or structural features include springs, viewing windows, and bladders. -
Treads 1116 extend relatively downward from thebase 1112. Thetreads 1116 may comprise blown rubber or carbon rubber, or a combination thereof. Thetreads 1116 may be solid, patterned, grooved, or otherwise adapted to confer fraction comparable to that provided by a running shoe. The tread cradle 1100 may be designed to look like the midsole and outsole of a running shoe. - A
receptacle 1130 extends relatively upward from thebase 1112 of the tread cradle 1100. Thereceptacle 1130 engages the cleat (not depicted) in a manner that is reversibly secure. As mentioned above, the footwear may have various patterns, including studs and/or blades, as described with reference toFIGS. 5 a-5 d. The tread cradle 1100 need not have substantially a mirror image correlation between the number and position of receptacles and the number and position of cleats. Rather, the number and position of thereceptacle 1130 corresponds to a key cleat in a preselected position, allowing the receptacle to engage the key cleat (not depicted) in a manner that is reversibly secure. Cleats that do not have corresponding receptacles interact with thezone 1112 a. The key cleat may be pre-selected based on mold continuities among certain brands, or mold continuities among certain sizes, or mold continuities due to process standardization. For example, inFIG. 10 , the key cleat is in the metatarsal region. Though not depicted, in footwear systems with replaceable cleats, the key cleat may be a specially adapted cleat that may be screwed in to provide a secure interaction with the receptacle, such as by a ball and detent engagement between the cleat and receptacle. - In operation, a tread cradle and footwear are removeably attached through a removably secure interaction between a cleat and a receptacle. Referring now to
FIG. 12 , acleat 1210 of athletic footwear (not depicted) having awear region 1210 a of abrasion resistant material is inserted into a receptacle 1230, which extends from abase 1212 of a tread cradle (not depicted, but similar to that depicted inFIG. 6 , or inFIG. 10 , or inFIG. 11 ). The receptacle 1230 compriseswalls 1232 defining anopening 1234. - A
lip 1236 is disposed adjacent to theopening 1234. Thelip 1236 is deformable and sufficiently elastic to allow thecleat 1210 to pass through theopening 1234. Thelip 1236 may stretch to surround the cleat, thereby reversibly securing the cleat, and hence its attached footwear (not depicted), to the tread cradle (not depicted). - The
walls 1232 further define areceptacle floor 1238. Thereceptacle floor 1238 may be the same material as thebase 1212. Thereceptacle floor 1238 may contribute no additional thickness to thebase 1212, or the receptacle floor may make the base thicker (such as for additional cushioning), or the receptacle floor may retain an EVA insert (not depicted) for additional cushioning beyond that provided by the base. Although not depicted, thereceptacle floor 1238 may be bored out, making thebase 1212 thinner, for a lower overall tread cradle profile. Thereceptacle floor 1238 may be treated, for example with a pressure-sensitive adhesive, to help retain thecleat 1210. As depicted, there is a small gap between thereceptacle floor 1238 and thecleat 1210, such that if thewalls 1232 are shaped to fit tightly with the cleat, and the cleat forced into the cradle by the weight of a user, a vacuum may develop in the gap, and thus suction forces may help to reversibly secure the cleat in the receptacle in addition to friction forces. - Referring now to
FIG. 13 , acleat 1310 of athletic footwear (not depicted) having awear region 1310 a of abrasion resistant material is inserted into an alternative tread cradle (not depicted, but similar to that depicted inFIG. 6 , except that this embodiment lacks uniquely-shaped receptacles, and thus may be used with a variety of cleat patterns and sizes). The tread cradle comprises abase 1312, sidewalls (not depicted, but similar to those ofFIG. 6 ), and treads (not depicted, but similar to those ofFIG. 6 ). Thebase 1312 may comprise polymer foams, ethylene and vinyl acetate (EVA), or polyurethane, or a combination thereof. A plurality ofrods 1360 extend relatively upwards from thebase 1312. Therods 1360 are depicted as evenly spaced, however, alternatively, the rods may be concentrated in areas corresponding to positions where cleats are traditionally found. Therods 1360 may be the same material as thebase 1312. Therods 1360 engage thecleat 1310 in a frictional fit according to the stiffness of the rods and their surface composition, thus reversibly securing the cleat. Therods 1360 may be treated, for example with a pressure-sensitive adhesive, to help secure thecleat 1310. Additionally, therods 1360 that are bent under thecleat 1310 may contribute additional cushioning. - Although not depicted, in footwear systems with replaceable cleats, the cleats may all be removed before engagement with the receptacle, thereby allowing a smaller gap between the footwear and the receptacle and/or to allow minor features become relatively more prominent once the cleats are removed. For example, a key feature (similar to that described in
FIG. 11 ) may be provided on the footwear that is relatively shorter than the replaceable cleats, but still sufficiently long to engage the receptacle and secure the base once the replaceable cleats are removed. - Yet another tread cradle is contemplated (not depicted). This tread cradle may use any, or a combination, of the foregoing methods for engaging the cleats. However, once removed from the footwear, the tread cradle may be used as a shinguard. The receptacles or rods may be minimized to prevent discomfort to the user, while the treads would be nonaggressive patterns consistent with the exterior surfaces of a conventional shinguard.
