FIG. 14 is an enlarged view of the area designated “14” inFIG. 5 of an embodiment of the disclosure. - With reference now to the drawings, and in particular to
FIGS. 1 through 14 thereof, a new protective footwear device embodying the principles and concepts of an embodiment of the disclosure and generally designated by thereference numeral 10 will be described. - As best illustrated in
FIGS. 1 through 14 , the ladder rungfootwear protection assembly 10 generally comprises a modification of conventional footwear and includes ashoe sole 12 having anoutsole 14, amidsole 16 positioned on theoutsole 14, and aninsole 18 is positioned on themidsole 16. Afoot surround 18 is attached to and extends upwardly from the shoe sole. More particularly, thefoot surround 18 may be attached tooutsole 14 along its perimeter edge. Thus, themidsole 16 andinsole 14 may be adhered to each other and each may be removable from a remainder of theassembly 10. For clarification, thefoot surround 18 includes an upper 20 and aheal counter 22. Discrete areas of themidsole 16 may be attached tooutsole 14, but, for reasons which will become clear below, will typically be substantially un-attached to the outsole. Theinsole 18 will be generally conventional and include cushioning and arch support features. - The foot surround 18 structure may include conventional structure for a tennis shoes, boots, and the like. Thus,
closures 24 including shoe laces, buckles, hook and loop closures may be utilized. Cushioning and supporting material may be positioned on or within thefoot surround 18. Other conventional structures may be utilized as well. For example, if theassembly 10 is to be used for a general work boot, the upper 20 may include a hardened insert to protect the person's toes. Theoutsole 14 will often include gripping materials and texture to enhance grip with a ground surface andladder rungs 26. - The
midsole 16 has anupper surface 28, alower surface 30, afront end 32, and arear end 34. Themidsole 16 facilitates flexion in a first direction allowing theupper surface 28 to become concavely arcuate along a line extending from thefront end 32 to therear end 34. Themidsole 16 resists flexion in a second direction to prevent theupper surface 28 from becoming convexly arcuate along a line extending from thefront end 32 to therear end 34. Because themidsole 16 does not convexly flex, theinsole 18, when placed on arung 26, will retain a shape as though theassembly 10 is placed on a flat surface. Consequently, a user's foot will be protected from fatigue and will not become sore due to their weight being spread out over theinsole 18 as opposed to only an area where theshoe sole 12 engages the rung. - In one embodiment as shown in
FIG. 2 , thelower surface 30 of the midsole includes a plurality ofbreaks 36 extending from a firstlateral edge 38 to a secondlateral edge 39 of themidsole 16. A plurality of sets ofabutting sections 40 is defined on opposite sides of each of thebreaks 36. Each of thesections 40 has alower edge 42 adjacent to thelower surface 30. Thelower edges 42 are movable away from each other to allow concave flexion in theupper surface 28 and abut each other when the midsole resists convex flexion of theupper surface 28. Thebreaks 36 are typically spaced from each other a distance of between 0.25 inches and 1.0 inch, and also include at least 4 breaks. - The
midsole 16 may comprise a plurality ofblocks 44 and aflexible panel 46. The plurality ofblocks 44 may form thesections 40 and thelower surface 30. Thepanel 46 forms theupper surface 28 and is secured to theblocks 44 opposite of thelower surface 30. Thepanel 46 is comprised of a flexible material to allow bending such that it functions as hinge relative to theblocks 44. Alternatively, theflexible panel 46 and theblocks 44 may be formed from a unitary structure wherein thebreaks 36 do not extend through theupper surface 28 and create a living hinge in theupper surface 28 connecting together eachsection 40. - In some embodiments, the
midsole 16 includes alower portion 48 and anupper portion 50. Thelower portion 48 comprises a plurality ofblocks 44 that are discrete with respect to each other and theupper portion 48 comprises apanel 46 that is resiliently flexible. Theupper portion 50 is adhered to the plurality ofblocks 44 such that adjacent ones ofupper edges 52 of theblocks 44 are retained in abutment with each other by thepanel 46 andlower edges 42 of theblocks 44 are selectively abutted against each other to prevent convex flexing of theupper surface 28. Adjacent ones of thelower edges 44 of theblocks 44 are movable away from each other to allow concave flexing of theupper surface 28. Theblocks 44 are comprised of generally rigid, non-compressible materials including plastics, carbon fiber, and elastomeric materials. - The
blocks 44 may each extend fully between the first 38 and second 39 lateral edges. However, as is evident fromFIG. 4 , the blocks may instead include a plurality blocks aligned to form rows extending between the first 38 and 39 lateral edges.FIG. 4 shows thebreaks 36 between the rows as well as dividinglines 54 defined between laterallyadjacent blocks 44 that are perpendicular to thebreaks 36. Thedividing lines 54 may be offset from each other from row to row to further allow independent flexing of the rows relative to each other. - A
second embodiment 56 and athird embodiment 58 are provided for inFIGS. 7-13 . Each of these embodiments is generally similar in function and construction as the first embodiment ofFIGS. 1-6 . However, as can be most clearly seen inFIGS. 8 and 12 , these embodiments do not include dividinglines 54 and therefore only including dividinglines 36. Thus, the abuttingsections 40 each fully extend asunitary blocks 44 from the firstlateral edge 38 to the secondlateral edge 39. Moreover, the portion of themidsole 16 containing the abuttingsections 40 may be spaced from thefront end 32 andrear end 34 as depicted inFIG. 12 . Thus, the portion of theupper surface 28 of themidsole 16 which resists convex arcing may be positioned only where best served while the user's foot is on therung 26. Areas without breaks, therefore, may extend from thefront end 32 and the rear end 34 a distance greater than 1.5 inches, and more typically more than 3.0 inches from therear end 34. - In use, the
assembly 10 is worn in a conventional manner as footwear. However, when worn on a ladder, theassembly 10 prevents the shoe from arcing around aladder rung 26. Typically when a foot is placed on therung 26, the weight of the person is concentrated on the area of their foot where it engages therung 26 and the inside of the user's footwear becomes, at least partially, convexly arcuate. Theassembly 10 prevents themidsole 16 from curving around therung 26 and thereby continues to spread the user's weight across theentire insole 18. In this manner, theassembly 10 prevents fatigue and soreness to the foot. However, by allowing concave flexing of theinsole 18, themidsole 16 does not interfere with the ability of the user to walk while wearing theassembly 10. - With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
- Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
