Abstract
A replaceable cap sleeve system is described herein which remedies the cost of acquiring multiple pairs of footwear by providing flexibility to match apparel. The system includes a base shoe structure having only a projecting heel, an insole, an outsole, and an instep area between a toe area and heel area, a removable toe sleeve adapted to extend over at least a portion of the toe area and insole of the base shoe structure, but which is attached to the underside of the base shoe structure at a location on the outsole, and a separate, removable heel sleeve adapted to be fastened over the projecting heel of the base shoe structure. A completed shoe for wear is realized that covers toes of a wearer and supports the wearer's heel with the toe and heel sleeves installed on the base shoe structure.
Description
- The present application claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application Ser. No. 62/440,159 to Karen E. Theisen, filed Dec. 29, 2016, pending. The entire contents of this provisional application is hereby incorporated by reference herein.
- The example embodiments in general are directed to a replaceable sleeve system for a shoe comprising at least a toe sleeve, with or without a heel sleeve, each adapted for connection to a base shoe structure to create a complete shoe.
- According to the National Shoe Retailers Association and the U.S. Census Bureau, as of 2014 the global footwear industry had annual revenues exceeding $52 billion dollars. Women's casual and dress shoes accounted for about 30% of that market share, or over $15.6 billion dollars.
- A 2010 survey conducted of 3000 women by gocompare.com and later reported in Glamour magazine indicated that the average woman will buy 469 pairs of shoes in her lifetime, spending over $25,000 or about $53 per pair, on average. The average woman has about 19 pairs of shoes at any given time.
- A more recent 2013 survey of 2352 women over the age of 18 conducted by VoucherCodesPro.co.uk echoed the 2010 survey. Namely, the study found that ladies owned about 20 pairs of shoes on average, yet they only placed five (5) pairs of these shoes into their regular rotation. The top excuse for neglecting their shoes was that the shoes were too uncomfortable (64% said that the shoes were either too tight on their feet or heels too high).
- However, the next largest excuse (at 55%) or reason that the women were not wearing many of their shoes, was because it was too hard to match the shoes to their outfit. Accordingly, what is desired is a shoe or system that allows a person greater flexibility in their shoe styles or designs so as to appropriately match the apparel of the person, which may also assist the person in conserving their annual outlay for footwear by purchasing fewer pairs of shoes.
- An example embodiment of the present invention is directed to a replaceable sleeve system adapted to complete a shoe for wear. The system includes a base shoe structure having only a projecting heel, an insole, an outsole, and an instep area between a toe area and heel area, a removable toe sleeve adapted to extend over at least a portion of the toe area and insole of the base shoe structure, but which is attached to the underside of the base shoe structure at a location on the outsole, and a separate, removable heel sleeve adapted to be fastened over the projecting heel of the base shoe structure. A completed shoe for wear is realized that covers toes of a wearer and supports the wearer's heel with the toe and heel sleeves installed on the base shoe structure.
- Another example embodiment is directed to a replaceable sleeve system adapted to complete a shoe for wear, where the system includes a base shoe structure having a projecting heel, an insole, an outsole, and an instep area between a toe area and heel area, the base shoe structure having a first connector attached thereto on an underside thereof. The system also includes a removable toe sleeve adapted to extend over at least a portion of the toe area and insole of the base shoe structure, the toe sleeve having a second connector attached thereto, the first connector on the underside of the base shoe structure adapted to receive the second connector therein to secure the toe sleeve to the base shoe structure, and a separate, removable heel sleeve attached over the projecting heel of the base shoe structure by a friction fit.
- Example embodiments will become more fully understood from the detailed description given herein below and the accompanying drawings, wherein like elements are represented by like reference numerals, which are given by way of illustration only and thus are not limitative of the example embodiments herein.

- The example embodiments to be described in more detail below are directed to a removable or interchangeable sleeve system that includes, in one example, a base shoe structure, with a toe sleeve and a heel sleeve adapted for connection to the base shoe structure such as high-heeled women's shoes to complete assembly thereof. In accordance with the example embodiments, the toe and heel sleeve is capable of being changed as desired without affecting the base shoe structure, thereby affording a means whereby the appearance of a shoe can be altered, as desired.
- Referring now to
FIGS. 1 through 10 , there is shown asleeve system 100 adapted for building a shoe according to an example embodiment.System 100 include abase shoe structure 110, atoe sleeve 120 and aheel sleeve 130. An upper rear end of thetoe sleeve 110 include amale connector 140. Afemale connector 150 is connected to theoutsole 118 on the underside of thebase shoe structure 110 and located at an upper end of theinstep area 119. Thefemale connector 150 is designed to receive themale connector 140 therein so as to secure thetoe sleeve 120, over thetoe cap 111 andtoe area 112 of thebase shoe structure 110, to theoutsole 118 thereof. - Once secured, the
toe sleeve 120 provides a throat or opening 123 that permits insertion of the toes, which are covered by thevamp 121 of thetoe sleeve 120. Although not shown in the drawings, at least part of the material that makes up thevamp 121 may be configured as an elastic portion to allow for give or flexibility in the width of thetoe sleeve 120, i.e., for comfort so that thetoe cap 111 on the base shoe structure does not pinch the toes. Once attached, theoutsole 122 of thetoe sleeve 120 partially covers theoutsole 118 of thebase shoe structure 110 and becomes the ground contacting surface subjected to weight bearing forces of the wearer, along with the heel tip of theheel sleeve 130. The material of thetoe sleeve 120 may be formed of any type of covering or material formed of plastics, leather, textile fabrics, or other suitable materials. - The
base shoe structure 110 on its top surface has only aninsole 113 with atoe area 112 and aheel area 114 thereon, it includes no vamp or toe area material whatsoever to secure toes of a wearer therein. This is provided only by thetoe sleeve 120. Thebase shoe structure 110 also has anoutsole 118 which arches through theinstep area 119 up to where it meets aheel breast 117 of a projectingheel 115 provided between aheel tip 116 and theheel breast 117. However, thebase shoe structure 110 includes no quarter or counter to secure a wearer's heel therein. This is provided by theattachable heel sleeve 130. - The
heel sleeve 130 include a hollow projectingheel 131 formed into aquarter 132 and acounter 133. Thequarter 132 comprises the upper rear and rear sides of theheel sleeve 130 that covers the heel of the wearer. Thecounter 133 offers stiffening while maintaining shape for theheel sleeve 130.Heel sleeve 130 also includes anankle strap 135. To install theheel sleeve 130 on the base shoe structure, theheel tip 116 of projectingheel 115 is inserted into theopening 134 of theheel sleeve 130 until it is seated completely within the hollow projecting heel, so that thequarter 132 covers the outside surface of theheel breast 117 and thecounter 133 withstrap 135 extends upward at the rear ofheel area 114. Theheel sleeve 130 is held onto thebase shoe structure 110 by friction created in theopening 134 between theheel 115 of thebase shoe structure 110, and the hollow projectingheel 131 of thehell sleeve 130, a “friction fit”. Also, the securing of theankle strap 135 around the ankle of the wearer provides additional means of holding theheel sleeve 130 onto thebase shoe structure 110. In an example, the hollow projectingheel 131 ofheel sleeve 130 may be form-fitted to the shape of the projectingheel 115. - As best shown in
FIGS. 1 and 2 , asolid heel tip 136, which may be formed of a metal such as steel or a hard plastic, is attached to the bottom of theheel sleeve 130. Namely, thissmall heel tip 136 is generally cylindrically shaped and has the same outside diameter as that of theheel sleeve 130, and is attached to the bottom of hollow projectingheel 131 by suitable fasteners, adhesives, and the like. Arod 137 extends from a top surface of theheel tip 136 within the interior of the hollow projectingheel 131. As theheel sleeve 130 is pulled up over the projectingheel 115 of thebase shoe 110,rod 137 is received in abore 138 that is formed in the underside of theheel tip 116 of thebase shoe 110, as best shown inFIG. 2 . This secures theheel tip 136 to the heel of thebase shoe structure 110.Heel tip 136 is provided so as to contact the ground and transmit the weight or load of the wearer to the inner, structural projectingheel 115 of thebase shoe structure 110 - In the example shown, the projecting
heel 115 andhollow heel 131 of theheel sleeve 130 are shown embodied as a thin, elongate heel or “stiletto” styled heel. However, it should be understood that both theheel 115 of thebase shoe structure 110 and theheel 131 of theheel sleeve 130 could be arranged in any shape or dimension. Components of thebase shoe structure 110, thetoe sleeve 120, andheel sleeve 130, like most men's and women's dress shoes, may be made of leather, usually entirely, including the uppers/outers, lining, and sole, though for more durability at the expense of elegance, many shoes are made with rubber soles. One or more of thebase shoe structure 110, thetoe sleeve 120, andheel sleeve 130 may also be fabricated from non-leather materials (plastic, synthetic leather). Typical raw materials include plastic, leather, wood, fabric, animal hides or combinations thereof, paper (for patterns and labels), and various cements and glues, depending on the component materials. Fasteners such as nails, screw nails, and tacks are typically used to hold the fabric or leather in place and to attach the projectingheel 115 to the shank ofbase shoe structure 100. - Referring now to
FIGS. 3-9 , themale connector 140,female connector 150, and the engagement therebetween to connect thetoe sleeve 120 to thebase shoe structure 110 is described in further detail. Themale connector 140 includes an L-shapedflange 141 having a flange extension surface 142 (forming a horizontal part of the L-shape) that connects or is otherwise attached to via any type of fastener, adhesive, sewn stitch, and the like to toesleeve 120. Theflange extension surface 142 can be attached to aninner surface 124 of the toe sleeve at an upperrear end 125 thereof, as shown inFIGS. 1 and 2 , to theoutsole 122 at an upper rear end 125 s shown inFIG. 10 , or to both surfaces. Awall 143 of theflange 141 that is perpendicular toflange extension 142 is connected to aflexible arm 144 extending rearward of thetoe sleeve 110. The flexible arm terminates in a disc-shapedsnap connector 145 that is to be received byfemale connector 150. Thesnap connector 145 includes a circumferentialvertical wall 146 and has abottom surface 147, which may be flat or beveled. - The
female connector 150 includes an L-shapedflange 151 having a flange wall 152 (forming a vertical part of the L-shape) that includes a central opening or slot 156 at the front offemale connector 150 therein that is to receive thesnap connector 145 andflexible arm 144 therethrough. A rearward facingflange 153 is integral with and forms part of theconnector body 154. As best shown inFIGS. 2 and 10 , the “top” surface of theflange 153 andconnector body 154 is attached, via any type of fastener, adhesive, sewn stitch, and the like, so as to be substantially flush up against the underside of thebase shoe structure 110 onoutsole 118. Namely,female connector 150 is attached or otherwise integral withoutsole 118 at a location that is the upper end of theinstep area 119 to where it meets theheel breast 117 ofheel 115. - The
slot 156 opens up into anelongate channel 155 formed in the interior ofconnector body 154 to permit lateral travel of theflexible arm 144 withsnap connector 145 of themale connector 140 therethrough. Thesnap connector 145 is received through the channel and flex engages a generallycircular recess 157 withvertical sidewalls 158 formed in theconnector body 154. As theflexible arm 144 flexes to snap fit thesnap connector 145 in place inrecess 157, thevertical side walls 146 of thesnap connector 146 engage and form an interference fit with thesidewalls 158 of therecess 157, such that a portion of thebottom surface 147 ofsnap connector 145 extends through therecess 157 and is accessible on the outside offemale connector 150. Accordingly, the engagement is a snap-in connection and themale connector 140 can be removed simply by pressingbottom surface 147 up intorecess 157 so as to be able to removemale connector 140 from thechannel 155 and slot 156 offemale connector 150. - Although the male/female connector arrangement has been described for connecting the
toe sleeve 120, and a friction-fit arrangement has been described to attach theheel sleeve 130, these are merely exemplary; there are various means of fastening thesleeves base shoe structure 110 to arrive at thesystem 100. In one alternative, fasteners such as hook-and-loop fasteners (i.e., Velcro) may be used to secure thetoe sleeve 120 andheel sleeve 130 to thebase shoe structure 110. To facilitate friction-based securement, additional elastic material may be employed in theheel sleeve 130. - In a further variant, the fastening means may be magnetic, such as the use of one or more magnets embedded in the materials of the
base shoe structure 110,toe sleeve 120, andheel sleeve 130. Exemplary magnets may include any of Neodymium magnets, Samarium cobalt (SmCo) magnets, also known as rare earth magnets, Alnico magnets, which are largely comprised of aluminum (Al), nickel (Ni), and cobalt (Co), aluminum and other trace amounts of elements such as copper (Cu) and titanium (Ti) to tailor the alloy's magnetic and mechanical properties. In an example such magnets could exhibit a pull force in a range of between about 1.6 to 4.9 pounds. In yet a further example construction,system 100 may be configured with one or more magnets exhibiting a pull force in a range of between about 2.0 to 3.0 pounds. - The
example sleeve system 100 may substantially reduce the number of pairs of footwear a person buys annually. Women may often buy many pairs of high heeled shoes, ostensibly due to the damage, such as scuff marks, incurred on the toe and/or heel, simply due to normal wear. Thesleeves system 100 eliminate this issue as thesleeves base shoe structure 110. - The present invention, in its various embodiments, configurations, and aspects, includes components, systems and/or apparatuses substantially as depicted and described herein, including various embodiments, sub-combinations, and subsets thereof.
