Each of these five patents and/or patent applications are included herein by reference in their entirety.

In the following description, the strapping described could be made of nylon, polyester, leather, rubber, plastic, cotton, elastic, or other materials. Similarly, the lacing could be made of paracord, nylon, polyester, leather, rubber, plastic, cotton, elastic, or other materials. The paracord loop, while made of paracord in the one embodiment, could be made of steel, aluminum, brass, other metals, plastic, polyester, nylon, leather, cotton, or other materials.

The present clog design contains three main webbing strap segments. The front two straps (hook strap 105, and ladder lock buckle strap 106) and the upper 111a, as can be seen in FIGS. 1-4 and 6, are all connected at the top of the foot by a soft and strong nylon paracord loop 104. The soft nylon loop 104 makes for a comfortable strap connection point that does not hurt the wearer's feet. The ladder lock buckle strap 106 is located on the outside of the wearer's feet for ease of use and comfort. The hook strap 105 is located on the inside of the wearer's foot. The third strap is the heel strap 109 and adjusts with a hook and loop fabric (such as Velcro®) through a metal loop hardware 121 in one embodiment. The loop hardware 121 could also be made of plastic, paracord, or other materials. In another embodiment, a G-hook heel strap 109 is used. The G-hook heel strap 109 also loops through the loop hardware 121 and the G-hook 115 hooks into one of the pockets 803a-d, allowing for adjustment.

Sole Assembly

The sandal strap system has 2 points anchored into the sole 101, and the upper 111a connects to the sole around most of the clog. In the one embodiment, the sole 101 is made of hard rubber material, such as Regolith™ Vibram® soles. The sole 101, the midsole 102, the footbed 103, the toe guards 119,120, and the wings 107,108 could be made of hard rubber, leather, plastic, wood, polyurethane (PU), TPR (thermoplastic rubber, combination of polyurethane and rubber), TPU (thermoplastic polyurethane), TR/TPR, EVA (ethyl vinyl acetate), EVA/RUBBER, nitro polyvinyl chloride, Pebax, or other materials.

The bottom of the sole 101 has a pattern for providing traction when walking or running. See FIG. 5. There are two anchor points located on the interior 107 and exterior 108 sides of the sole 101 by the wearer's ankle. The interior 107 and exterior 108 sides of the sole 101 are referred to as wings herein. The sole 101 could be molded to include the wings 107,108 as well as the toe guard 120 (and perhaps toe guard 119).

The hard rubber of the sole 101 extends upwards above the rest of the sole 101 on either side of the ankle to form an interior wing 107 and an exterior wing 108. These wings 107, 108 connect to wing straps 117,118. The wing straps 117 and 118 could be the same strap, running between the footbed 103 and the midsole 102. The wing straps 117 and 118 are connected to the heel strap 109, the hook strap 105, and the buckle strap 106.

In one embodiment, the sole 101 is glued to a midsole 102, and a footbed 103. The wings 107,108 are part of the mold for the sole 101. The midsole has a molded pattern and is glued in between the wings 107, 108. On the inside of the wings 107, 108, webbing 117, 118 is sewn to the hard rubber wings 107,108. The webbing runs from the interior wing 107 between the midsole 102 and the footbed 103 in a channel to the exterior wing 108, where it is again sewn. The webbing 117, 118 extends above the wings 107, 108 on both sides, and connects to the heel strap 109, the hook strap 105, and the buckle strap 106. This webbing 117,118 could be a single piece of webbing that runs through a cutout channel in the midsole 102, providing a connection for the webbing 117,118 on the interior wing 107 and the exterior wing 108. The midsole channel prevents an uneven surface on the foot side of the midsole 102.

The upper 111a, b, c is glued between the midsole 102 and the footbed 103 from the back to the front of the clog.

The sole 101 could have a toe guard 120 extending upwards on the front of the clog, protecting the midsole 102 and the footbed 103. The midsole 102 could have an additional toe guard 119 protecting the front of the footbed 103 and the upper 111a.

The midsole 102 could be molded to have an ergonomic shape on the footbed 103 to provide comfort to the user. The mold of the midsole 102 could incorporate the toe guard 119 in some embodiments.

Upper

A shaped piece of material called the upper 111a,b,c encompasses the front and top of the user's foot. The upper is glued to the midsole 102 and the footbed 103 around the circumference of the footbed 103. The upper 111a,b,c may be glued to the inside of the toe guards 119,120. At the top, the upper 111a could connect to the paracord loop 104 through a tab 110. The tab 110 could extend over the top of the upper 111a as a tongue loop 116. In other embodiments, the tongue loop 116 is a separate piece of material.

The upper 111a,b,c could be made of leather (cowhide, pigskin, deerskin, ostrich skin, crocodile skin, snakeskin, etc.), canvas, polyvinyl chloride (PVC), polyurethane, nubuck leather, microfiber, mesh, nylon, metal net, cloth, suede, and similar materials.

In some embodiments, the upper 111a,b,c have vents 112a,b,c,d cut into the material. The vents 112a,b,c,d could vary in shape, size, number and location.

In some embodiments, the upper 111a extends beyond the wings 107,108 to a back upper area 111b,111c.

In some embodiments, the upper 111a,b,c is sewn to the midsole 102. In some embodiments, the upper 111a,b,c is sewn to the sole 101. In other embodiments, the upper 111a,b,c is glued to the sole 101.

Adjustment Mechanisms and Features

Heel Strap

As seen in FIGS. 2 and 7, the heel strap 109 begins at the interior wing strap 117. The heel strap 109 is sewn together with polyester webbing on the outside and a loop and hook fabric (such as Velcro®) on the inside, in some embodiments. The heel strap is sewn to the interior wing strap 117 and wraps behind the heel, then through a metal loop 121 connected to the exterior wing strap 118. The heel strap 109 loop portion of the hook and loop fabric is facing away from the heel as the heel strap 109 threads through the mechanical ring 121, and the end of the heel strap 109 beyond the ring has the hook portion of the hook and loop fabric. The heel strap 109 folds through the mechanical ring 121 back on itself, adhering using the hook and loop fabric (Velcro®). The heel strap 109 gives quick and intuitive adjustment to tighten or loosen the sandal tightness at the hindfoot (the back of the foot above the heel). Note that Velcro® is a mechanical fabric hook and loop fastening system.

G-Hook Heel Strap

In the alternative embodiment seen in FIG. 1,2,7, the heel strap 109 is replaced with a G-hook system as seen in FIG. 8. For wearers engaged in water activity as well as anything highly active in the outdoors, they may prefer a heel strap 109 that is more durable and less prone to fail than hook+loop Velcro. A heel strap 109 with one continuous piece of webbing will completely eliminate any chance of hook+loop heel strap delamination (failure) in wet and muddy conditions as well as found with long-term Velcro wear+tear from years of use. Although the single continuous webbing heel strap solves this durability issue, it offers no adjustment whatsoever, leaving wearers with a less than ideal fit. Typically, this creates a heel strap that is not secure and snug up against the heel.

We have used our G-hook technology to design a failure-proof heel strap that is completely adjustable to fit each unique wearer perfectly. The new G-hook heel strap 109 provides a customized fit that wearers seek, yet, will provide sturdy and failure-proof support while swimming, submerged in water, traversing muddy terrain, and in any environment whatsoever that would traditionally pose problematic for a hook+loop closure system. The G-hook heel strap 109 also provides far more long-term durability than a hook+loop alternative as there is no wear with continual adjustment use.

The G-hook heel strap 109 consists of at least two layers of webbing (webbing pile). A wider webbing (20 mm) 109 touches the wearer's heel, and a narrower webbing 801 matches the width of the G-hook 115 and is sewn into the wider webbing with Hook Pocket bartack stitches 803a-c. The webbing pile begins at the inside sole hugger wing strap 118, wraps around the foot and through an aluminum loop 121 (attached to the outside sole hugger wing strap 117), then wraps back around the foot, ending with the G-hook 115 which can hook into any variety of Hook Pockets 803a-d. The further the G-hook 115 wraps back towards the inside of the foot, hooking into an available Hook Pocket, the tighter the heel strap will fit the wearer. Depending on size there may be up to 10 hook positions 803a-d available for the G-hook adjuster. Once the G-hook 115 is hooked into the hook pockets 803a-c, the G-hook heel strap 109 will be fully secure for all outdoor activities.

A third layer of webbing may be sewn into the webbing pile of the G-hook heel strap 109 to provide the wearer with a cushion between the G-hook hardware 115 and the heel of their foot. The multiple layers of webbing help create a sturdy, yet comfortable heel strap. Alternatively, a thicker, more plush wide webbing can be used to create this layer of comfort.

Ladder Lock Buckle Strap Adjustment

The ladder lock buckle strap adjustment 113 is located on the outside of the foot. The buckle strap 106 is anchored to both the paracord loop 104 at one end and the exterior wing strap 118 at the other end. The buckle strap 106 is actually two pieces of webbing, a first buckle strap piece sewn in a loop around the paracord loop 104 at one end and the second buckle strap piece sewn in a loop around the ladder lock buckle 113 (or similar mechanical connection device 113). The second buckle strap piece of webbing is sewn to the exterior wing strap 118 at one end and loops through the ladder lock buckle 113 at the other end, allowing the user to pull the buckle strap 106 to shorten the length, thereby tightening the clog. The buckle strap 106 adjusts tightness through a ladder lock buckle 113. The ladder lock buckle 113 could be made of acetal plastic in one embodiment, but could also be made of could also be made of aluminum, steel, stainless steel, zinc alloys, brass, bronze, titanium, other metals, carbon fiber, polypropylene, nylon, plastics, or similar materials. Tugging the tag end of webbing 106 through the buckle 113 tightens the system. This adjusting mechanism is simple to use and is used as an everyday adjuster for tightening, loosening, putting the clogs on, and taking them off.

Hook Strap

As seen in FIG. 3 and FIG. 4, the hook strap 105 serves as an extremely useful mechanism for customizing the fit of the sandal for each wearer's preferences during both casual and intense activities. The hook strap 105 tighten or expands the overall volume of the strap system and controls the angle at which the upper 111a strikes the top of the wearer's foot. It is critical to be able to adjust the angle of the upper 111a on the clog for ideal comfort through various activities and for various foot sizes. The hook strap 105 creates an ideal mechanism for this adjustment process as it is very flexible, comfortable, durable, and strong. Unlike a hook and loop fabric (Velcro®) adjuster in this area, the hook strap 105 will not come undone during water activities like swimming, and cliff jumping.

The hook strap 105 could be composed of a custom-molded plastic ½″ G-hook 114, two different widths of webbing 105, 801, and a series of bartack stitches 802a-e. The narrower ½″ webbing 801 is sewn into the wider ¾″ polyester tubular webbing 105 at consistent intervals. In between each of these bartacks 802a-e leaves a ½″ long gap (hook pocket) 803a-d between the ½″ and ¾″ straps for the G-hook 114 to fit in. The G-hook 114 is sewn to the end of flat ½″ webbing 801 and is the terminating point of the hook strap 105. The G-hook 114, 115 could also be made of different sizes and materials such as aluminum, steel, stainless steel, zinc alloys, brass, bronze, titanium, other metals, carbon fiber, acetal, polypropylene, nylon, plastics, or similar materials.

The non-hook end of the Bedrock Hook strap 105 is sewn into the front end of interior wing strap 117. The hook strap 105 is then looped through the paracord loop 104 back on itself. The G-hook 114 then has 3-5 different ½″ long hook pockets 803a-d between the ½″ webbing 801 and ¾″ webbing 105 to hook into. This range gives the wearer the ability to tighten or loosen the hook strap 105 and thus change the orientation of the upper 111a. Of course, the size of the strapping here and throughout this document could be varied without deviating from the design.

Sole Wings

The sole wings 107, 108 provide wearers with more lateral stability and comfort compared to a traditional clog design. The sole wings 107, 108 and their straps 117,118 provide two strong and durable anchor points for the strap system to connect to on either side of the wearer's ankle. There are two sole wings, an interior sole wing 117 on the inside of the clog, and an exterior sole wing 118 on the outside for the clog.

The wing consists of both a 1.5-inch-wide webbing straps 117, 118 and rubber wings 107, 108 from the sole 101 that wrap up and above the midsole 102 and the footbed 103. The 1.5-inch-wide webbing runs as a continuous piece above the midsole 102 in a channel between the midsole 102 and the footbed 103. The webbing 117,118 is then folded over and sewn into the rubber wing 107, 108. This fold creates two gaps (front and back) for the Bedrock Cairn Strap System 105,106,109 to connect to.

FIG. 6 shows the front view of the clog. The sole 101 with its toe guard 119 is at the bottom of the figure. The toe guard 119 could be molded into the sole 101 or glued to the sole 101. The second toe guard 119 could be molded into the midsole 102 or glued to the midsole 102. Alternatively, the second toe guard 119 could be molded into the first toe guard 120 or glued to the first toe guard 120. Upper 111a is glued to the midsole 102 and the footbed 103, and may be glued to the toe guards 119,120. The tab 110 is sewn into the upper 111a and attaches to the paracord loop 104. The buckle strap 106 loops through the paracord loop 104 and back to the buckle 113. The G-hook strap 105 loops through the paracord loop 104 and back to the G-hook 114. The G-hook is inserted into the pockets 803a,b,c,d. In FIG. 6, the G-hook 115 is in pocket 803b, and pockets 803c,d is not visible behind the G-hook 114.

FIG. 7 shows a rear view of the clog, with a view of the inside of the clog. The sole 101 forms the base, with the midsole 102 glued to the sole 101, and the footbed 103 glued to the midsole 102. The upper 111a,b,c can be seen on the sides and the top. The upper 111a,b,c is glued between the midsole 102 and the footbed 103. The heel strap 109 loops through the loop 121 and back on itself where the G-hook 115 hooks into the pockets 803a,b,c,d. In FIG. 7, the G-hook 115 is in pocket 803c, and pocket 803d is not visible behind the G-hook 115.

The foregoing devices and operations, including their implementation, will be familiar to, and understood by, those having ordinary skill in the art.

The above description of the embodiments, alternative embodiments, and specific examples, are given by way of illustration and should not be viewed as limiting. Further, many changes and modifications within the scope of the present embodiments may be made without departing from the spirit thereof, and the present invention includes such changes and modifications.
