This single piece design of a substantially rigid support member preferably allows for increased protection of portions 332, 334 and 336 of upper 304 and the associated parts of the foot. In particular, using a single piece of material that is conformed to the shape of upper 304 helps to prevent pressure points that may result from creases or regions that are unprotected. Instead, the current design provides for any weight being applied to support member 340 to be distributed equally over portions 332, 334 and 336 of upper 304.

FIGS. 4-10 are intended to further illustrate preferred embodiments of various provisions associated with the different components associated with a preferred embodiment. In particular, provisions associated with sole 301 and strap 338 and support member 340 are discussed in further detail.

Preferably, article of footwear 106 includes slip-resistant provisions. In some embodiments, article of footwear 106 may include a sole configured to provide extra traction in wet conditions. In a preferred embodiment, the sole may include provisions for channeling water away from article of footwear 106 in order to increase traction.

FIG. 4 is an exemplary embodiment of bottom portion 400 of sole 301. Preferably, bottom portion 400 includes first central channel 402 and second central channel 404. In some embodiments, first central channel 402 and second central channel 404 may have grooves disposed in bottom portion 400. Preferably, channels 402 and 404 extend from forward end 408 to rear end 410 of bottom portion 400.

In some embodiments, bottom portion 400 may also include lateral channels 412. Preferably, lateral channels 412 extend from medial side 414 to lateral side 416 of bottom portion 400. In this preferred embodiment, lateral channels 412 may intersect central channels 402 and 404. In this embodiment, lateral channels 412 are generally perpendicular to central channels 402 and 404, however in other embodiments, lateral channels 412 could be disposed at any angle with respect to central channels 402 and 404.

Referring to FIG. 5, a close up of a preferred embodiment of first portion 418 of bottom portion 400, channels 402, 404 and 412 form grooves in sole 301. In some embodiments, tread elements 420 may be disposed between channels 402, 404 and 412. In a preferred embodiment, tread elements 420 extend a height H1 above base surface 422. In some embodiments, height H1 may range from 0.1 millimeters to 5 millimeters. In a preferred embodiment, height H1 has a value of 1 millimeter.

Generally, the widths of channels 402, 404 and 412 may vary. In this embodiment, second central channel 404 has a width W1. Preferably, the widths of channels 402 and 412 are substantially similar to width W1 of second central channel 404. The value of width W1 may vary between 0.1 millimeters and 2 millimeters. In a preferred embodiment, width W1 has a value of 1 millimeter.

Referring to FIGS. 4-5, central channels 402 and 404 define a central contact region 430. In particular, central contact region 430 includes the region between central channels 402 and 404. Preferably, central contact region 430 is configured to engage a surface first. If the surface is wet, water is preferably channeled away from central contact region 430 via channels 402, 404 and 412. In a preferred embodiment, water moves longitudinally through central channels 402 and 404 and laterally outwards through lateral channels 412. Using this preferred configuration, as water is generally directed out from under bottom portion 400, tread elements 420 may more easily contact the surface. This arrangement helps prevent slipping due to losses in friction caused by water disposed between tread elements 420 and the surface.

In some embodiments, sole 301 may include additional provisions for increasing traction on wet surfaces. In this preferred embodiment, bottom portion 400 also includes large recesses 440 disposed at ball region 442. Typically, a majority of weight is put on the ball of the foot. Therefore, as a wearer steps down, excess water contacting ball region 442 may be pumped away with greater efficiency through large recesses 440.

In some embodiments, bottom portion 400 may also include additional curved channels. In this preferred embodiment, bottom portion 400 may include curved channels 450. In some cases, curved channels 450 may provide additional traction during pivoting, as bottom portion 400 may rotate about ball region 442. In other embodiments, curved channels 450 may provide additional longitudinal channels for the water to move along, thus increasing the distribution to lateral channels 412.

In some embodiments, bottom portion 400 may also include provisions for increasing traction at heel region 460. To provide increased traction as the heel is lowered, heel region 460 may include U-shaped channels 462. These channels preferably facilitate the pumping of water away from heel region 460, especially at central contact region 430.

It should be understood that large recesses 440, curved channels 450 and U-shaped channels 462 are optional. In other embodiments, only some of these provisions may be incorporated into bottom portion 400. In still other embodiments, none of these additional provisions may be used. Generally, by including some of these additional provisions, the type of traction achieved may be modified. Additionally, varying height H1 associated with tread elements 420 and width W1 associated with channels 402, 404 and 412, the amount of traction may also be varied.

Using these provisions associated with sole 301, article of footwear 106 may be configured to provide increased traction on a wet surface. This feature is especially important for articles of footwear used in various sports such as sailing, canoeing, kayaking and similar water sports. As helmsman 100 steps on boat 102, rocks or other wet surfaces, sole 301 may facilitate reduced slipping.

This arrangement for sole 301 is only intended to be exemplary. In another embodiment, sole 301 could include a different type of tread pattern. Generally, any type of tread pattern known in the art may be applied to sole 301 to provide increased traction. In a preferred embodiment, sole 301 may include a herringbone type tread pattern.

FIG. 11 is a preferred embodiment of bottom portion 1100 of sole 301. In some embodiments, bottom portion 1100 includes tread pattern 1102. In this preferred embodiment, tread pattern 1102 is a herringbone pattern. Preferably, tread pattern 1102 may include ridges 1104 and channels 1106. Ridges 1104 and channels 1106 may be configured in wave like arrangements. This arrangement allows for increased traction with a surface by channeling water through channels 1106.

In the embodiment shown in FIG. 11, tread pattern 1102 is applied to the entirety of bottom portion 1100. However, in other embodiments, tread pattern 1102 may be applied to only a portion of bottom portion 1100. For example, tread pattern 1102 could be applied to front portion 1110, middle portion 1112, rear portion 1114 as well as any combination of these portions. Additionally, in other embodiments, bottom portion 1100 could include additional structural features as well, including any of the structural features discussed and illustrated in FIGS. 4 and 5.

Preferably, article of footwear 106 includes provisions for easily fastening upper 304 and sole 301 to a foot. In some embodiments, article of footwear 106 includes some kind of fastening straps. In a preferred embodiment, article of footwear 106 may include additional fastening provisions.

Using this preferred configuration, secondary fastener 610 may be configured to tighten upper 304, especially at ankle collar 306.

Preferably, secondary fastener 610 may be further associated with extendable portion 630 of upper 304. Preferably, extendable portion 630 is made of an expanding material such as neoprene or similar types of materials. In this embodiment, when secondary fastener 610 is in an unfastened position (as seen in FIG. 6), extendable portion 630 may open to allow helmsman 100 to more easily slip their foot into article of footwear 106. Later, as secondary fastener 610 is fastened, extendable portion 630 may contract around the foot as upper 304 is tightened.

Referring to FIGS. 6 and 7, the fastening of article of footwear 106 preferably begins by closing secondary fastener 610. In this embodiment, secondary fastener 610 may be ‘zipped’ up to ankle collar 306. Then, strap 338 may be wrapped around medial side 620, rear side 622 and finally lateral side 624, as seen in FIG. 7. As strap 338 wraps around medial side 620, strap 338 may cover secondary fastener 610. This preferred arrangement may prevent secondary fastener 610 from accidentally coming unfastened or ‘unzipped’ during use.

Preferably, lateral side 624 includes second fastening region 702. In this embodiment, second fastening region 702 is disposed on ankle collar 306. As free portion 604 of strap 338 extends around to lateral side 624, first fastening region 606 preferably engages second fastening region 702. In a preferred embodiment, fastening regions 606 and 702 may be complementary sides of a hook and loop fastener, such as Velcro®. Using this preferred arrangement, ankle collar 306 of upper 304 may be tightened around a foot using strap 338. This arrangement may help decrease the tendency of large amounts of water to splash into upper 304 and cause irritation or other problems to helmsman 100.

Referring to FIGS. 6 and 7, article of footwear 106 may include provisions for increasing traction at the front and rear sides of upper 304. In this embodiment, a front side of article of upper 304 may be associated with front gripping members 652. Likewise, a rear side of upper 304 may include rear gripping members 650. Front gripping members 652 and rear gripping members 650 may be optional in some embodiments. In a preferred embodiment, article of footwear 106 may include both front gripping members 652 and rear gripping members 650.

In this embodiment, front gripping members 652 may be attached to support member 340. Also, rear gripping members 650 may be attached to sole 301. In other embodiments, one or more sets of gripping members could be disposed on upper cover 330 as well.

Generally, gripping members 650 and 652 may be made of any material. Preferably, gripping members 650 and 652 are made of a material such as rubber that helps to increase traction. Additionally, gripping members 650 and 652 may have any shape. In this preferred embodiment, gripping members 650 and 652 have hemispherical shape. With this preferred arrangement, gripping members 650 and 652 may be used to increase traction between article of footwear 106 and various components of boat 106 (see FIG. 1). In some cases, gripping members 650 and 652 may provide increased traction with cross bar 114 and another surface of boat 106.

In this preferred embodiment, upper 304 may be attached directly to sole 301 in order to prevent water from entering upper 304. In other embodiments, however, article of footwear 106 may include provisions to increase air flow through upper 304, especially at toe portion 336. This arrangement may also allow some water to enter upper 304.

FIG. 8 is a side view of an alternative embodiment of front portion 800 of article of footwear 106. Generally, support member 340 is configured to attach to sole 301 at second periphery 802. In some embodiments, support member 340 may not attach to the entirety of second periphery 802. In a preferred embodiment, support member 340 is configured to allow front tip 804 of upper 304 to be exposed.

In this alternative embodiment, support member 340 includes first periphery 806. In some embodiments, first periphery 806 includes peripheral portion 808. In this embodiment, peripheral portion 808 is preferably spaced from second periphery 802. In a preferred embodiment, peripheral portion 808 is preferably spaced a distance D1 from second periphery 802. With this preferred arrangement, front tip 804 of upper 304 may be exposed, allowing increased airflow in and out of upper 304 at toe portion 336.

The current embodiment discusses the orientation of support member 340 with respect to sole 301. However, it should be understood that a similar discussion applied to upper cover 330. In particular, upper cover 330 and support member 340 may be coincident at front portion 800 of article of footwear 106, so that upper cover 330 includes a periphery that is coincident with first periphery 806 of support member 340.

As previously discussed and illustrated in FIG. 2, helmsman 100 may need to plant one or more articles of footwear beneath cross bar 114 to maintain balance while steering boat 102. Preferably, an article of footwear is configured to facilitate associating a foot with 114 during sailing.

Referring to FIG. 9, prior designs for articles of footwear for sailors have not included provisions to increase traction of an article of footwear with cross bar 901 as well as increased support for the helmsman. In this exemplary embodiment of a prior design, article of footwear 900 is wedged between cross bar 901 and wall 915 of a boat. In this embodiment, as the helmsman leans back, cross bar 901 applies increasing pressure to upper 908 of article of footwear 900. In this case, upper 908 is not made of a substantially rigid material and therefore, upper 908 partially deforms at first portion 910. This configuration generally results in increased pressure applied directly to first region 912 of foot 914.

With this prior design, foot 914 and article of footwear 900 may hyper extend under increased pressure on the toes of foot 914 to retain a position under cross bar 901. This arrangement may make it difficult to maintain contact at wall 915. Additionally, article of footwear 900 does not include any traction increasing provisions as are provided in the preferred design discussed previously. This arrangement could result in slipping between article of footwear 900 and cross bar 901 and wall 915 of the boat. Eventually this may lead to slipping that may result in helmsman 100 losing his or her balance.

FIG. 10 is intended to illustrate a preferred embodiment of the current design. In this embodiment, article of footwear 106 preferably includes support member 340. In this case, as helmsman 100 leans back, cross bar 114 is pressed against support member 340 at first portion 1010. Because support member 340 is made of a substantially rigid material, support member 340 does not deflect or bend. In particular, the force applied to support member 340 by cross bar 114 is evenly distributed over upper 304 and in some cases, the majority of this pressure is distributed to sole 301 via the connection between support member 340 and sole 301. This preferred arrangement generally increases support to the helmsman.

It should be understood that the positioning of cross bar 114 with respect to article of footwear 106 is only intended to be exemplary. In other embodiments, cross bar 114 may be disposed against another portion of support member 340. Generally, anywhere cross bar 114 may contact support member 340 will be non-deforming. Furthermore, heel member 316 generally provides increased protection for heel 1004 of foot 1002 as article of footwear 106 is pressed back against wall 1006. This arrangement helps to increase traction and provide additional support for the helmsman.

Generally, sole 301, heel member 316 and support member 340 may form a rigid system. This rigid system may help to prevent the type of hyper extension that occurs in some prior designs. Using this preferred configuration, article of footwear 106 may be configured to maintain a fixed position with respect to cross bar 114 and wall 1006. This configuration may help to keep helmsman 100 steady during the operation of boat 102.

As previously discussed, article of footwear 106 also includes gripping members 650 and 652 configured to provide increased traction. Preferably, front gripping members 652 may be disposed against cross bar 114. Likewise, rear gripping members 650 may be disposed against wall 1006. Using gripping members 650 and 652, article of footwear 106 may be prevented from slipping with respect to cross bar 114 and wall 1006. This preferred configuration may help helmsman 100 maintain stability and stay within boat 102.

While various embodiments of the invention have been described, the description is intended to be exemplary, rather than limiting and it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible that are within the scope of the invention. Accordingly, the invention is not to be restricted except in light of the attached claims and their equivalents. Also, various modifications and changes may be made within the scope of the attached claims.
