Definitions
- Extent of forward trunk lean is an important aspect of weightlifting and powerlifting, particularly in movements that involve a squatting motion. Excessive forward trunk lean can result in undesirable shear stresses in the lower back area.
- Weightlifting shoes are often used to address excessive trunk lean and limited ankle flexibility. Such shoes are built up in the heel area to present a wedge- shaped longitudinal cross section. As a result, the ankles are not required to bend to the extent that would be necessary in a flat-footed squatting movement. Also, the raised heel of the user can make it easier for the user to avoid excessive forward trunk lean. Furthermore, the thighs can be lowered and raised in a stable fashion with improved vertical spinal alignment, when compared with lowering and raising in a flat-footed condition. -
- Such shoes generally result in the heel being raised about 25 mm. However, there does not appear to be a specific minimum or maximum height.
- an accessory for a shoe comprising:
- the heel support member is configured to engage, in a releasable manner, at least opposite sides of the shoe when a heel of the shoe is supported by the heel support member, the heel support member being configured to raise the heel of a user by a predetermined extent.
- the heel support member may have a substantially flat bottom surface and a substantially flat top surface.
- the top surface may be angled with respect to the bottom surface so that an operative back of the support member is thicker than an operative front of the support member.
- the support member may be wedge- shaped.
- the accessory may include one gripping member that extends about at least the back of the support member.
- the accessory may include a pair of opposed gripping members, extending along respective sides of the support member and at least partially about the back of the heel support member.
- the gripping members may be spaced or may abut each other over a line that bisects the heel support member.
- the gripping members may be of a resiliently deformable material.
- the gripping members may be shaped so that they deform to accommodate at least the heel of the shoe, so setting up a bias that facilitates engagement with the heel of the shoe.
- the material may be selected so that the bias is sufficient to cause the gripping members to grip the shoe to retain the accessory in position, allowing the user to move around without the accessory falling off the shoe.
- Shoes usually have some form of "upper" connected to the sole.
- the upper and the sole often define a furrow or channel at their juncture.
- the gripping members may define inwardly extending retaining formations that are configured to be received in the furrow or channel.
- the retaining formations may be configured to engage sides of the shoe sole.
- the gripping members and the support member may define a volume into which a user can slide the shoe, while worn, from the front to the back.
- Soles of shoes that are conventionally worn for exercise or sport are generally of an expanded, resiliently flexible material, such as a foam, for example an EVA foam.
- the retaining formations may be configured to at least partially embed themselves in the sides of the sole. This serves to inhibit disengagement of the sole and the retaining formations while the user or wearer moves around and even jumps without fear of the accessory dislodging.
- the accessory may include a roller assembly that is mounted in the heel support member.
- the roller assembly may include a roller that extends rearwardly from a back of the heel support member. The roller may be offset from the bottom surface to avoid interference with the floor.
- the roller assembly may include a carrier.
- the roller may be mounted, in a rotatable manner, on the carrier.
- the heel support member may define a recess in which the carrier can be mounted in a releasable manner.
- the gripping members may be mounted on respective sides of the heel support member.
- the gripping members may be adjustable towards and away from each other so that differently sized shoes can be accommodated.
- Each gripping member may include wall portions that define the retaining formations.
- the wall portions may extend upwardly from respective sides of the heel support member.
- One or more mounting lugs may extend generally at right angles to each wall portion.
- Each mounting lug may be received in a corresponding recess defined by the heel support member.
- the recesses and the mounting lugs may be configured so that the gripping members can be displaced towards and away from each other with the mounting lugs sliding to and fro in the respective recesses.
- a fastening mechanism may be provided to engage the mounting lugs when a desired position of the gripping members is achieved. The fastening mechanism may be releasable so that the gripping members can be re-adjusted to suit different users.
- the accessory may be an assembly of two bases to define the heel support member and two shoe gripping members anranged on respective bases.
- Each base may defines at least two passages, the passages of respective bases being capable of being brought into register with each other, the accessory including fasteners that can be received through respective passages so that the bases can be fastened to each other.
- the accessory may include an adjustable spacing arrangement to permit the bases to be spaced from each other to a desired extent to adjust an overall width of the accessory.
- the spacing arrangement may include at least one spacer that can be received between at least the bases, the, or each spacer being shaped to accommodate the fasteners so that the bases can be fastened to each other with the spacers sandwiched between the bases.
- the spacing arrangement may include a plurality of the spacers.
- each, spacer may have a profile that corresponds with that of the bases and the gripping members such that edges of the spacers are flush with the bases and the gripping members to define continuous, even surfaces.
- the overall width of the accessory may be adjustable by locating spacers between the bases and gripping members.
- the accessory can include a number of spacers of predetermined thickness. A desired number of spacers can be selected to achieve a required overall width of the accessory.
- the base portions and the spacers may define at least two sets of corresponding openings that can be brought into register or alignment with each other so that fasteners in the form of fixing screws or tie rods can be received through respective sets of openings to fasten the base portions together with the spacers sandwiched between the base portions.
- the spacers and the base portions may have complementary locating or alignment formations or structures that engage each other when the base portions are fastened together. Thus, relative rotational movement of the components can be inhibited during use.
- The, or each, gripping member may include a wall that extends from a periphery of the support member.
- the wall may have at least one heel gripping formation that extends inwardly into a zone defined by the support member and the, or each, wall.
- The, or each, gripping formation may be configured to engage a sole or other part of the shoe when the shoe, worn by the user, is positioned in the zone thus inhibiting release of the shoe from the accessory when the shoe is lifted.
- The, or each, gripping formation may be in the form of a ridge extending along the wall, the ridge projecting into the zone so that a shoe, worn by a user, can be slid operatively backwards into the zone such that the gripping formation at least partially embeds itself into the sole or other part of the shoe.
- The, or each, gripping member may include a wall that extends from a periphery of the support member and that is angled inwardly with respect to the support member.
- the heel support member may define a passage, a strap being receivable through the passage, the strap being configured so that the accessory can be strapped to the shoe if necessary.

- the member 14 can be of a resiliently deformable plastics material, such as synthetic rubber or can be of a natural rubber.
- the gripping member 14 can deform to accommodate at least a heel of the shoe, so setting up a bias that facilitates
- the gripping member 14 defines an inwardly extending retaining formation 26 that is configured to be received in a furrow or channel defined by a juncture of the sole of the shoe and the upper of the shoe.
- the inwardly extending retaining formation 26 can be configured to grip the heel of the shoe .
- the heel support member 12 is configured to provide a substantially rigid support.
- the heel support member 12 can be of a high density artificial or natural rubber or other plastics or polymeric material.
- both the gripping member 14 and the heel support member 12 are of a material that facilitates moulding of the members 12, 14.
- the heel support member and gripping member 12, 14 are in the form of a one-piece moulding.
- the heel support member 12 is of a material selected to provide a suitable coefficient of friction to inhibit slippage of the sole of the shoe, in use.
- the heel support member 12 defines a flared base 28.
- the base 28 provides stability. It also allows a user to use the front or the side of an opposite shoe to push the accessory 10 from the shoe without having to bend down.
- reference numeral 30 generally indicates another embodiment of an accessory for a shoe. With reference to figures 1 to 3, like reference numerals refer to like parts, unless otherwise specified. The use of common reference numerals is not intended to limit the scope of the appended claims.
- the accessory 30 has a pair of opposed gripping members 32, separated at the back 20 of the support member 12. Each gripping member 32 extends upwardly from a respective side of the support member 12 and partially about the back 20 of the support member 12. Thus, a gap 34 separates the gripping members 32. It is to be understood that the gap 34 is optional. Instead, the gripping members 14 can touch each other and even overlap, if necessary.
- Each gripping member 32 includes a wall or wall portion 36 that defines an associated retaining formation 26.
- the wall portions 36 extend upwardly from respective sides 38 of the heel support member 12.
- Two mounting lugs 40 extend generally at right angles to each portion 36.
- Each mounting lug 40 is received in a corresponding recess 42 defined by the support member 12 in each side 38.
- the recesses 42 and the mounting lugs 40 are configured so that the gripping members 14 can be displaced towards and away from each other with the mounting lugs 40 sliding to and fro in the respective recesses 42.
- the accessory 30 includes a roller assembly 46 that is mounted in the support member 12.
- the roller assembly 46 includes a roller 54 rotatably mounted on a carrier 48.
- the carrier 48 includes a pair of mounting legs 50 receivable in a pair of corresponding recesses or sockets 52 defined by the member 12 and extending into the member 12 from the back 20.
- the roller 54 and the sockets 52 are configured so that the roller 54 is offset upwardly with respect to the bottom surface 16.
- reference numeral 60 generally indicates another embodiment, according to the invention, of an accessory for a shoe.
- like reference numerals refer to like parts, unless otherwise specified. Use of common reference numerals is not intended to limit the scope of the appended claims.
- the accessory 60 includes a pair of gripping members 62 that extend upwardly from opposite sides 64 of the support member 12.
- the gripping members 62 operate in a similar manner to the gripping member 14 and the gripping members 32. It follows that when a user slides the shoe into the zone 24 heel-first, the gripping members 62 serve to retain the accessory 60 in position on the shoe.
- Applicant envisages that the accessory will find application in sporting activities that can require a rapid change in foot orientation.
- An example of such an activity or sport is that known as "cross-fit".
- sport or training it is often necessary to change from running to weightlifting, for example.
- Shoes with a relatively small heel- drop and flexible soles are popular for running. However, such shoes are not optimal for weightlifting, which usually requires more heel-drop and stiffer soles .
- the accessory can be engaged: with the shoe after running. This can happen relatively quickly and without the user having to bend down and make adjustments. This can occur, for example, when the shoe is slid, heel-first into the zone 24. Thus, the user can transition to weightlifting, for example, relatively quickly.
- the gripping members 14 allow the accessory to be disengaged from the shoe, again without bending down. For example, this can be achieved by the user pushing a toe portion of the opposite shoe against the flared base 28 to push or lever the accessory off the shoe.
- the roller assembly 46 is configured to facilitate the performance of a number of exercises.
- the user can perform a handstand with the rollers 54 bearing against a wall. In that position, the performance of handstand push-ups is enhanced since movement of the shoe heels relative to the wall is not hindered by frictional engagement.
- the roller assembly 46 can provide a significant advantage.
- Figure 8 shows a user without the roller assembly 46. As can be seen, it is necessary for the user to maintain a generally vertical orientation while performing the handstand push-ups.
- Figure 9 shows a user with the roller assembly 46. With the roller assembly 46, the user is able to orientate him- or herself at an angle significantly offset from the vertical.
- reference numeral 70 generally indicates a further embodiment, in accordance with the invention, of an accessory for a shoe. With reference to figures 1 to 10, like reference numerals refer to like parts, unless otherwise specified.
- the accessory 70 includes an assembly of two base portions or bases 74.1 , 74.2 and two shoe gripping members 72.1 , 72.2 arranged on respective bases 74.1 , 74.2.
- Each gripping member 72 includes a wall 76 that extends or projects upwardly from a periphery of the base portion 74.
- the bases 74.1 , 74.2 and the walls 76.1 , 76.2 are configured so that they can be attached together such that the assembled accessory 70 defines a heel support member 77 with the walls 76 extending about the heel support member 77 and projecting upwardly from a periphery of the heel support member 77.
- the members 72.1 , 72.2 when the members 72.1 , 72.2 are connected together, they define a substantially flat bottom surface 73 and a substantially flat top surface 75.
- the top surface 75 is angled with respect to the bottom surface 73 so that a back of the support member 77 is thicker than a front of the support member 77.
- the support member 77 is generally wedge-shaped.
- the heel support member is dimensioned to raise the heel of the user by a predetermined amount, such as between about 10 mm and 40 mm or some other height depending on the
- said predetermined amount could be about 25 mm.
- Each of the walls 76 includes a side portion 78 and a rear or back portion 80. Heel gripping formations in the form of ridges or ribs 82 extend inwardly from internal surfaces of the side and rear portions 78, 80. Furthermore, each of the walls 76 is sloped inwardly. The characteristics of the sloped walls 76 and the ridges 82 facilitate the gripping of a heel of a shoe within a zone 84 defined by the heel support member 77 and the walls 76.
- the ridges 82 are selected or configured so that they can embed at least partially into at least the heel of the shoes worn by the user.
- the inventor has performed trials with over one hundred pairs of shoes of the type that would usually be worn by persons performing weightlifting exercises, circuit training, or the type of training known as "cross-fit".
- the configuration of the ridges or ribs 82 are a result of such trials.
- the ridges have a frontal, sloped profile.
- the ridges can have a generally rectangular cross-section. Alternatively, they can be peaked or define apices when viewed in cross -section. In either configuration, a user is able to slide the heels of his or her shoes backwards into the respective zones 84. This results in the ridges at least partially embedding themselves into the heels or soles.
- the user is able to walk about with the accessories 70 connected to his or her shoes. Furthermore, this level of engagement between the accessories 70 and the shoes can be achieved without the user having to bend down and perform any form of adjustment or fitting.
- This is useful in the type of training or sport known as "cross -fit". As is known, in such training or sport, it is necessary for a user often to rapidly change between one form of exercise and another. In the event that the accessories 70 are used, the user can rapidly change between one form of exercise in which a flat-footed stance is appropriate and another form of exercise in which the feet should be inclined, for example, during a weightlifting exercise such as squatting.
- the bases 74 define corresponding passages 86 that extend from one side to the other between the walls 76.1 , 76.2.
- Fasteners in the form of tie rods or threaded fixing screws 88 extend through respective passages 86.
- Each of the fixing screws 88 has a threaded end. The threaded end of each fixing screw 88 engages a threaded insert 90 that is positioned in a socket 91 that terminates each passage 86.
- a hexagonal bung or cap 92 can be received in each socket 91 to cover the insert.
- Each of the fixing screws 88 includes a head 94.
- the heads 94 of the tie rods 88 are received in the sockets 91.
- a cap 95 can engage each head 94 within an associated socket 91 for aesthetic purposes.
- a width of the zone 84 is adjustable to suit different shoe sizes.
- the accessory 70 includes a number of spacers 96 that can be received between the bases 74 and the back portions 80.
- Each spacer 96 has a profile that corresponds with a profile of each base 74 and back portion 80.
- each spacer 96 has a base portion 97 that corresponds with the bases 74 and a projection 99 extending from a rear end of the base portion 97 and corresponding with the back portion 80 of the walls 76.
- each spacer 96 defines openings 98 that correspond with the passages 86 to accommodate the fixing screws 88.
- Each spacer 96 has a predetermined thickness so that the number of the spacers 96 can determine a width of the zone 84.
- At least the wall 76 can be of a resiliently flexible material. This allows flexing of the wall 76 to receive the heel of a shoe and also to facilitate retention of the accessory 70 on the heel of the shoe.
- a ground pad 100 is attached to a bottom surface of each base 74.
- the ground pad 100 can be of a relatively rigid material to provide stability to the accessory 70.
- a rear surface 102 of the base 74 and the back portion 80 defines a recess 103.
- the recess 103 is configured so that a user can engage the accessory 70 with an opposite shoe to remove the accessory 70 by levering or pushing the accessory 70 off the shoe.
- This feature together with the ridges or ribs 82 provides a mechanism by which the user can rapidly engage the accessories 70 with, or detach the accessories 70 from, his or her shoes by engaging the recess 103 with the toe or side of, a shoe.
- the bases 74 and the spacers 96 define a slotted opening or passage 104.
- a strap 106 (figures 18 and 19) can be received through the passage 104.
- An adjustable fastening assembly in this example, a buckle assembly 108 is arranged on the strap 106.
- a user can strap the accessory 70 to his or her shoe further to secure the accessory 70 to the shoe.
- the strap 106 can be used to retain the accessory 70 together as a single unit. This can be useful in training or sports sessions which are predominantly weightlifting.
- the strap 106 can be a Velcro strap that can engage itself in a conventional manner using a buckle or the like.
- reference numeral 1 10 generally indicates an exemplary embodiment of an accessory for a shoe.
- like reference numerals refer to like parts, unless otherwise specified. Such common use of reference numerals is not intended to limit the scope of the appended claims.
- the accessory 110 includes a pair of rubber soles 1 12 that are fastened to respective bases 74. These can provide grip on a floor during rigorous exercise.
- Each base 74 defines a series of laterally extending grooves or channels 114. These can serve to reduce shoe slippage. Such shoe slippage can be reduced when a user lands during an Olympic weightlifting movement such as split jerks and snatches. As the shoe and the accessory land after such a movement, the grooves 114 help to grip a sole of the shoe and to stop the shoe from sliding forwards.
- the spacers 96 and the bases 74 include locating or alignment formations or structures that engage each other when the bases 74 are fastened together. These are configured to inhibit relative rotational movement of the components. In other words, they provide a level of torsional rigidity about a lateral extending line.
- the locating or alignment formations include a number of projections or buttons 116 that extend from the base 74.1 and the spacers 96 to nest in recesses in a spacer 96 closest to the base 74.1 , adjacent spacer(s) 96 and the base 74.2.
- the bases 74 and the spacers 96 can lock together when the fixing screws 86 are tightened.
- Figure 21 shows a cross-sectional detail of the ribs 82.
- the ribs 82 have a generally rectangular cross-section and define a groove between them.
- the ribs 82 can have a thickness of between about 0.5 mm and 4.0 mm, for example about 2.0 mm.
- the ribs 82 project from the walls 76 by between about 0.5 mm and 3.5 mm, for example, about 1.6 mm.
- the ribs 82 could be further customised with different dimensions to suit different footwear.
- the position of the ribs 82 relative to the bases 74 together with their dimensions has been determined in accordance with a study of over 100 shoes of the type worn for training and sports.
- two ribs 82 are shown. However, there could be one rib or three or more ribs.
- the bases 74 and the walls 76 are of a thermoplastic elastomer.
- the spacers 96 are also of a thermoplastic elastomer. It will be appreciated that these components could be fabricated from other materials, as well.
- the accessory can have a variety of dimensions depending on the requirements. However, it is envisaged that a pair of accessories, supplied with a suitable number of spacers and fixing screws of suitable length can be used with substantially all. conventional forms of training or sports shoes.
- the accessory can have an overall length of between about 100 mm and 200 mm, for example, about 140 mm.
- the accessory can have an overall height of between about 30 mm and 60 mm, for example, about 48 mm.
- the walls can extend from the support member between about 15 mm and 30 mm, for example, about 23 mm.
- the walls are also angled inwardly at an angle of between about 65 degrees and 85 degrees, for example, about 77 degrees.
- the walls have a slope with a pitch of between about 2 mm and 8 mm, for example, about 5 mm.
- the spacers can be of various thicknesses. In one example, the spacers can vary from about 1 mm to 4 mm in thickness, such as about 2.5 mm in thickness.
- a pair of the accessories can be supplied with a set of the spacers, allowing the user to adjust the width of the accessories to suit his or her shoes by using more or less spacers or selecting one of a number of spacers of different thicknesses.
- the inventor envisages that the accessory need not be provided with a set of spacers with the same thickness.
- the accessory can include a number of spacers of different thicknesses so that the selection of a certain spacer can be made to adjust the overall width of the accessory.
- the spacers can be provided so that the overall width of the accessory can vary from about 85 mm to 100 mm. It will be appreciated that this can be increased by providing more or different spacers and longer fixing screws.
- the accessory can be attached or detached from the shoe in a hands-free manner. Furthermore, when attached, a user can perform movements such as walking, running and jumping. Detachment is simply carried out by engaging an opposite shoe with the recess or cut-out in the back of the heel member, as described above.
