The present invention generally relates to footwear, and more specifically relates to footwear and footwear systems that include snakebite protective material.
A majority of snakebites occur below the knee and when a person is walking through heavy undergrowth areas. Some types of footwear have characteristics that protect the user against snakebites. These types of boots are commonly called “snakebite boots”. Snakebite boots are typically taller than standard shoes or boots to better protect the user's lower leg against snakebites. Taller boots can be uncomfortable due to the significant surface area of the boot upper that is engaging and rubbing against the user's leg. Snakebite boots usually include either a tight fit construction that is maintained tight against the user's leg with a set of adjustable laces, or is loose fit to reduce the amount of contact of the boot upper with the user's leg.
There is a need to address these and other issues involved with snakebite boots.
The present invention relates to footwear assemblies that include snakebite resistant materials. An example footwear assembly includes a sole assembly and an upper portion secured to the sole assembly. The upper portion includes a tightening structure that extends up a portion of the height of the footwear assembly, and an extension of snakebite material positioned above the tightening arrangement.
The extension of snakebite material is typically loose fit around the user's lower leg.
The tightening arrangement provides adjustable tightening of the footwear assembly about the user's foot and lower leg at locations below the extension of snakebite material. The extension of snakebite material can be integral with the rest of the footwear assembly, or can be releaseably mounted to the remainder of the footwear assembly in the form of a gaiter structure. The footwear assembly can include snakebite resistant material that covers substantially all of the surface area of the upper portion. Additional support, waterproofing, and padding layers or materials can be used throughout the footwear assembly.
The above summary of the present invention is not intended to describe each disclosed embodiment or every implementation of the present invention. The Figures and the detailed description that follow more particularly exemplify certain embodiments of the invention. While certain embodiments will be illustrated and describe embodiments of the invention, the invention is not limited to use in such embodiments.
The present disclosure generally relates to footwear that is adapted to resist puncture or penetration from, for example, a snakebite. The present disclosure is directed to at least two general configurations. In the first configuration, the footwear is a boot style footwear that includes snakebite resistant material that extends from a top end of the boot to the sole portion of the boot. The footwear includes a tightening arrangement that extends only partially up the height of the boot, preferably to at least an ankle portion of the boot. The top end of the boot is constructed to provide a relatively loose fit around the user's lower leg (i.e., below the knee and above the tightening arrangement). In a second configuration, a footwear assembly includes a footwear such as a boot and a removable gaiter. Both the boot and the gaiter include snakebite resistant material. The gaiter can be permanently or removably mounted to the boot.
Snakebite resistant materials have been used in footwear and other clothing in the past.
The invention can be more completely understood with reference to the above descriptions and the following examples. The examples included herein are given for illustrative purposes only and should not be construed as limiting the scope of the invention to what is illustrated and described herein. The same or similar reference numbers are used throughout the figures for those features that are common.

Footwear assembly 10 includes an upper 12 and a sole assembly 14. The upper 12 includes a tightening arrangement 20 that extends only partially up a total height of the footwear assembly 10. The upper 12 further includes a foot portion 22, an ankle portion 24, a top portion 26, an instep portion 28, a top end 30, and a bottom end 32. The foot portion 22 includes a forefoot portion 21, a midfoot portion 23, and a hindfoot portion 25 as shown in
The tightening arrangement 20 includes a set of laces 34, a plurality of eyelets 36, a tongue member 38, reinforcing material 40, and an upper boundary 42 (see
The eyelets 36 illustrated in
The reinforcing material 40 is shown extending along significant portions of the footwear upper 12 from the sole assembly 14 to a height H1 (see
The height of the upper boundary 42 can also be defined as that portion of the upper extending from a top portion of the sole assembly 14. This distance can be calculated by subtracting the thickness T of the sole assembly 14 from the height H1.
The material of footwear upper 12 that extends above the upper boundary 42 can be defined as a snakebite material extension 45 (see
The snakebite material extension 45 has an opening 49 along the top end 30 as shown in
The snakebite material extension 45 preferably has a cross-sectional area measured at any location between the upper boundary 42 and the opening 49 that is also sized greater than the user's leg.
The tightening arrangement 20 is shown including a set of laces 34 and eyelets 36. In other arrangements, the laces 34 can be used in combination with or replaced by other adjustable tightening features or arrangements such as, for example, a hook and loop arrangement, straps, buckles, cable systems and the like.
Some example snakebite resistant materials include, for example, those materials disclosed in U.S. Pat. Nos. 5,837,623 and 5,565,264. Some commercial snakebite resistant materials include SNAKEGUARD produced by Emtex Inc. of Danvers, Me., TURTLESKIN made by Warrick Mills of New Ipswich, N.H., and VIPERCLOTH used in Chippewa brand boots. Some other example materials that may be applicable include Kevlar, aramid (aromatic polyamide) fabric, and other synthetic fiber fabrics that are resistant to penetration.
Snakebite resistant material can be characterized by some of the material components and properties of the material. For example, some snakebite resistant materials include a stitch bonded polyester or a spun bonded polypropylene. Some such materials can have properties of breatheability while still maintaining resistance to puncturing with a sharp object such as snake fangs that are applied to the material with significant force or at non-perpendicular angles relative to a primary surface of the material.

The upper 12 includes a snakebite resistant material 44, a waterproof layer 46, and a padding layer 48 (see
The tongue member 38 can provide an expandable gusset in the upper 12 to accommodate different sizes of the user's foot and lower leg. Typically, the tongue member 38 includes snakebite resistant material. The tongue can be constructed as a separate member from the snakebite material extension 45 and the tightening arrangement 20. In other arrangements, the tongue member 38 can be a continuous or integral with the snakebite material extension 45. The snakebite material extension 45 and tongue 38 can be characterized as a gaiter member that is formed integral with and permanently mounted to the footwear assembly 10.
The footwear assembly 10 includes a snakebite resistant material along the entire height of the footwear upper 12, while the tightening arrangement 20 extends along only a portion of the height of the footwear assembly 10. There can be multiple kinds or types of snakebite resistant material used in the footwear upper 12. Alternatively, the same type of snakebite resistant material can be used throughout the footwear upper 12. Further, the snakebite resistant material can be a continuous piece throughout the upper 12, or can comprise several individual pieces of snakebite resistant material that abut, overlap, or are secured or otherwise attached to each other. The upper 12 can also include multiple layers of snakebite resistant material, for example, in areas where additional protection is desired.
The snakebite resistant material can be included as a layer within the construction of footwear assembly 10 at any desired location. For example, the snakebite resistant material can be positioned as the outermost layer of the footwear assembly 10 to define an outer exposed surface thereof. In another example, the snakebite resistant material is included as an embedded layer in the construction of the footwear assembly 10.
The Example Footwear Assembly of
The upper 112 includes a tightening arrangement 120, a foot portion 122, an ankle portion 124, an instep portion 128, a top end 130, and a bottom end 132. The upper 112 also includes a snakebite resistant material 144 that extends throughout much if not all of the outer surface area of the upper 112. The snakebite resistant material 144 typically extends from at least the top end 130 to the bottom end 132. A padding layer 148 can be included on at least a portion of the interior surface area of the upper 112.
The tightening arrangement 120 includes a set of laces 134, a plurality of eyelets 136, a tongue member 138, first and second reinforcing materials 140, 141, and an upper boundary 142. Some of the plurality of eyelets 136 are positioned on the first reinforcing material 140. Others of the plurality of eyelets 136 are positioned on the second reinforcing material 141. The tightening arrangement 120 extends from the foot portion 122 through the ankle portion 124 along the instep portion 128 of the footwear 110. The upper boundary 142 is positioned near the top end 130 of the upper 112. Typically, the upper boundary 142 is positioned within, for example, about 0.5 to about 2 inches of the top end 130. Alternatively, an uppermost eyelet 136A (see
The footwear 110 further includes first and second side boot connectors 180, 182, and a rear boot connector 184; The connectors 180, 182, 184 are configured to connect with a plurality of gaiter connectors positioned on the gaiter 160, as will be described in further detail below.
The footwear 110 typically has a height H1 in a range of about 4 to about 12 inches, preferably about 6 to about 10 inches, and more preferably in the range of about 8 to about 10 inches (see
The gaiter 160 includes a top end 162, a bottom end 164, a zipper closure assembly 166, and a connection assembly 168. When the gaiter 160 is mounted to the footwear 110, the bottom end 164 is positioned vertically lower than the top end 130 of the upper 112. The top end 162, as shown in
The zipper closure assembly 166 is shown in a closed state in
In still further arrangements, the gaiter 160 can be void of any closure mechanism such that the gaiter maintains a permanent cylindrical shape and cannot be adjusted into the open state shown in
In another arrangement, the gaiter 160 can comprise an elastic construction that permits inserting the footwear through the gaiter 160 to position the gaiter 160 on the user's lower leg after the footwear 110 has already been positioned on the user's foot. In a still further arrangement, the gaiter 160 can have an internal size sufficiently large to permit mounting of the gaiter 160 over the footwear 110 after the footwear has been positioned on the user's foot. In this arrangement, the gaiter 160 could be at least partially tightened around at least the bottom end 164 using some type of tightening construction so as to provide a desired mounted state to the footwear 110 while still providing a loose fit around the user's leg at the open top end 162.
In some cases, the gaiter 160 can include a cinching member 143 along the top end 162. The cinching member 143 can provide at least a partial closure or reduction in the size of the opening into the top end 162 of the gaiter 160 when the zipper closure assembly 166 is in the closed state.
The connection assembly 168 includes first and second side gaiter connectors 170, 172 and a rear gaiter connector 174 as shown in
The gaiter 160 includes snakebite resistant material 176. The snakebite resistant material 176 is shown extending over substantially the entire surface area of the gaiter 160. In some arrangements, portions of the gaiter 160 can be void of snakebite resistant material. For example, that portion of the gaiter 160 that overlaps with the ankle portion 124 of the footwear 110 does not necessarily require snakebite resistant material to provide protection of the user's ankle and foot in that area because of the snakebite resistant material 144 positioned on the footwear 110. Alternatively, portions of the footwear 110 that overlap with portions of snakebite resistant material 176 on the gaiter 160 can be void of snakebite resistant material.
Each of the footwear 110 and gaiter 160 can include multiple layers of snakebite resistant material. Also, portions of the snakebite material 144, 176 can be covered with additional materials such as the reinforcing materials 140, 141 on the footwear 110, or additional reinforcing, aesthetic, or other functional materials (e.g., waterproof and padding) or layers. The snakebite resistant materials 144, 176 can be the same type of snakebite resistant material. Alternatively, the materials 144, 176 can be different types of snakebite resistant material while still providing the desired properties of resistance to snakebites. The footwear assembly 110 can be characterized as including a first material (e.g., a snakebite resistant material) that extends from the top end 162 of the gaiter 160 to the bottom end 132 of the upper 112, and a second material (e.g., one of the first and second reinforcing materials 140, 141) that extends over only a portion of the footwear assembly (e.g., to the height H1 or the upper boundary 142). The footwear assembly 100 can also be described as having a tightening arrangement that extends up to only a portion of the height of the footwear assembly (e.g., H1) while a substantial portion of the footwear assembly (e.g., the gaiter 160) extends above the tightening arrangement and does not include a tightening arrangement so that the portion of the footwear assembly 100 above the tightening arrangement can be loose fit on the user's leg.
The gaiter 160 can comprise materials that provide the gaiter 160 as a free-standing structure, particularly when the zipper closure assembly 166 is in the closed state. When the gaiter 160 has a free-standing construction, the gaiter 160 can remain standing vertically upward when supported at only a single end (e.g., the bottom end 164) by the footwear 110. The gaiter 160 does not require any further attachment, tightening or engagement structures for engaging the user or the user's clothing at any point above the point of connection between the gaiter 160 and the footwear 110.
