Definitions

  • This invention relates to a sole for an item of footwear such as a boot or a shoe, and particularly, but not exclusively, to a sole for a running shoe.
  • the invention also relates to a shoe comprising such a sole.
  • the energy absorption is predominately provided by muscle in the runner. This energy is very different from the "impact” or “shock” energies of heel strike, which typically have high frequency components, and may be dissipated by fatty tissues such as those found in a runner's heel pads or man-made trainer heels.
  • heel strike running is preferred by many runners due to the current design of running shoes such as trainers. These shoes tend to have good heel protection.
  • the resulting stance in which the heel strikes the ground first may be viewed as a running form of the normal walking heel-sole-toe stance. Absorption of energy and opposition of force by muscle is metabolically costly, and can induce or exacerbate muscle soreness and injury including "shin splints".
  • a sole for an item of footwear comprising: a front portion;
  • an energy absorbing member positioned within the front portion, and having a first position in which the energy absorbing member protrudes from the sole, and a second position in which the energy absorbing member is substantially level with a surface of the sole.
  • the energy absorbing member may be a mechanical energy absorbing member.
  • the energy absorbing member is particularly suitable for absorbing mechanical energy during the first half of the runner's stance.
  • Embodiments of the invention thus comprise a passive mechanical device adapted to absorb a significant proportion of the energy to be absorbed and to reduce the forces on eccentrically loaded (dissipating) muscles such as the tibialis anterior which is associated with shin splints.
  • a passive mechanical device can be lightweight.
  • Embodiments of the present invention reduce the demand for energy absorption by muscles of the runner, especially by reducing the loading on the shin muscles (including the tibialis anterior). In addition, by means of the present invention energy may be absorbed more rapidly. This may have potential benefits to the running style of a runner.
  • the heel portion of the sole will be that part of the sole that will support the heel of a person wearing a shoe into which the sole is incorporated.
  • the heel portion of the sole may be regarded as any portion of the sole behind the ankle when a wearer of the footwear item is in a standing position.
  • the front portion of the sole is any area other than the heel portion.
  • the sole may define a substantially flat surface in which case there will be no definite division between the front portion and the heel portion of the sole which portions will merge into one another.
  • the heel portion may be distinct from the front portion.
  • the energy absorbing member may be positioned to be under the ball of the foot of a wearer of the item of footwear.
  • the energy absorbing member may protrude from the sole by between 10 and 40mm when in the first position. In embodiments of the invention, when the energy absorbing member moves to the second position, it deflects by the same distance by which it protruded from the sole in the first position.
  • the force required to achieve full deflection of the energy absorbing member may be in the range of 50% to 150% of the body weight of a wearer of an item of footwear incorporating the sole. In one embodiment of the invention, the force required for full deflection is approximately 100% of the body weight of a person wearing the item of footwear. In other embodiments of the invention, the force required may be less than 50% or greater than 150% of the body weight of a wearer of the item of footwear. In embodiments of the invention, the energy absorbing member is provided at least partially in a recess in the sole.
  • the recess may be shaped to receive the energy absorbing member, and to accommodate any change in shape of the absorbing member occurring between the first position and the second position.
  • the recess may be formed by cutting into the sole.
  • the recess may comprise padding.
  • the padding may be positioned over an inner surface of the recess.
  • the purpose of the padding is to spread the force exerted on a wearer of the item of footwear, thereby reducing the pressure applied between the absorbing member and the foot of the wearer.
  • the padding may maintain a plastic deformation, allowing the absorbing member to be consistently sited under the ball of the foot of a wearer. The plastic deformation may be slight.
  • the sole may comprise an outer layer extending over the energy absorbing member.
  • the outer layer is adapted to hold the energy absorbing member in place, and in embodiments of the invention comprising a recess in the sole, the outer layer is adapted to hold the absorbing member within the recess. In such embodiments, the outer layer is adapted to extend at least partially over the sole to thereby cover the recess.
  • the outer layer may be formed from an elastic or resilient material.
  • the outer layer provides protection to the energy absorbing member, and prevents dirt and other foreign bodies from entering the recess.
  • the outer layer is adapted to hold the energy absorbing member in place whilst still allowing the energy absorbing member to move between the first and second positions.
  • the energy absorbing member may be elastic or resilient.
  • the energy absorbing member may comprise a ball.
  • the ball may be any suitable ball.
  • the ball may comprise a squash ball.
  • the energy absorbing member may be of a different shape, for example cylindrical, cubic, or donut shaped, for example.
  • the energy absorbing member may be formed integrally with the sole. In such embodiments a region, or the entire sole may comprise the energy absorbing member.
  • the energy absorbing member is made from rubber, or a rubber-like material. In other embodiments of the invention, the energy absorbing member may be made from a sponge-like material or a foam material.
  • the recess will be shaped to allow for an increase in the cross- sectional area of the squash ball when in the second position in which the ball is deflected to assume a position in which it is substantially level with the sole of the shoe. This means that the recess will have a greater cross-sectional area than the ball when the ball is in the first position in which it is undeflected.
  • the sole comprises a single energy absorbing member only. Such an arrangement is likely to be suitable for smaller sized footwear such as footwear for children or women.
  • the sole comprises a plurality, of energy absorbing members.
  • the sole comprises two energy absorbing members. Such an arrangement is particularly suitable for larger sized footwear such as footwear for use by men.
  • an item of footwear comprising a sole having:
  • a energy absorbing member positioned within the front portion, and having a first position in which the energy absorbing member protrudes from the sole, and a second position in which the energy absorbing member is substantially level with a surface of the sole.
  • the item of footwear may comprise a running shoe.
  • the running shoe may have a substantially flat sole. In such an embodiment there will be no clear demarcation between the front portion and the heel portion of the sole.
  • the shoe may be adapted for use by an 80kg man.
  • each of the energy absorbing members may comprise a ball, such as a squash ball.
  • Each squash ball is adapted to deflect 15 to 20mm into the second position under a load of 1000N, absorbing approximately 4 Joules and returning approximately 0.4J (that is 10% elasticity, or 90% hysteresis dissipation).
  • Embodiments of the invention comprise a sole for an item of footwear, or an item of footwear incorporating a sole, the sole comprising an energy absorbing member positioned such that in use the energy absorbing member is positioned under the ball of the foot of a wearer.
  • the energy absorbing member is adapted to deflect from between 10 to 40mm when the item of footwear hits the ground during a running movement of the wearer.
  • the force for full deflection may be approximately 100% of the body weight of the wearer of the item of footwear. No further deflection of the energy absorbing member occurs after it has become substantially level with a surface of the sole of the item of footwear.
  • Figure 1 is a schematic representation of an item of footwear according to an embodiment of the invention
  • Figures 2 to 4 are schematic representations showing the energy absorbing member of Figure 1 moving from a first position to a second position and back to the first position;
  • Figure 5 is a schematic representation of a second embodiment of the invention showing two recesses adapted each to hold a energy absorbing member
  • Figure 6 is a schematic representation of a third embodiment of the invention having a single recess adapted to hold a single energy absorbing member
  • Figures 7 and 8 are representations of further embodiments of the invention showing footwear comprising an outer layer extending partially over the sole in order to cover the energy absorbing member;
  • an item of footwear according to an embodiment of the invention is designated generally by the reference numeral 2.
  • the item of footwear is in this example a running shoe and comprises a sole 4 according to an embodiment of the first aspect of the invention.
  • the sole 4 in this example has a substantially flat surface, although in other embodiments, there may be a recess.
  • the sole comprises a heel portion 6 and a front portion 8 which are not distinct from one another.
  • the recess may serve to separate the heel portion 6 from the front portion 8.
  • the shoe 2 further comprises a energy absorbing member 10 which in this embodiment comprises a ball 12.
  • the ball comprises a squash ball, although other balls may also be suitable.
  • the sole 4 comprises a recess 14 shaped to receive the ball 12.
  • the recess is formed by cutting into the sole but leaving the inner sole 16 of the shoe intact.
  • the recess comprises a layer of padding 18 positioned between the ball 12 and the inner sole 16.
  • the padding provides cushioning and cushions the force exerted on the shoe by the ball 12.
  • the ball has a first position as shown in Figure 1 in which it protrudes beyond the sole 4.
  • the presence of the ball 12 serves to absorb energy and to oppose forces created during running. The invention thus reduces the demand for energy absorption by muscles, especially by reducing the load on the shin muscles (including tibialis anterior).
  • the ball 12 in use, acts under the ball of a foot of a wearer of the shoe 2.
  • the ball will protrude 15 to 30mm beyond the sole 4 and will therefore deflect by this amount when the foot of a runner wearing the shoe strikes the ground.
  • a user of the shoe 2 is using a heel strike stance, and the heel portion 6 of the shoe 2 has hit the ground.
  • the absorber 10 is in the first position and protrudes from the sole 4 and is in an undetected state.
  • the runner puts his whole foot down onto the ground and the absorber assumes the second position in which the absorber has been deflected and compressed so that it does not now protrude beyond the sole.
  • the ball In this position, the ball will have a greater cross-sectional area than when it is in the first position due to the compression, and the recess 14 is shaped to accommodate this increase in cross-sectional area. Because of the resilient nature of the absorber, when the runner continues to begin to lift his foot off the ground, the absorber returns to its original undeflected state and returns to the first position. In so doing, the ball 12 returns energy to the runner by applying force to the ground during unloading. This action protects biological tissues including shin muscles, during loading by moving the centre of pressure forwards. It also and has the ability to allow more rapid energy absorption than is favoured by muscles because the energy can be absorbed by the energy absorbing member over a short duration, i.e., with a high negative power.
  • the sole 4 comprises two recesses 14 each of which is adapted to hold an energy absorber 10 in the form of a ball 12.
  • This embodiment is particularly designed for larger shoe sizes 20.
  • Figure 6 third embodiment of the invention is shown comprising two smaller sized shoes 21 , 22.
  • the sole 4 comprises a single recess 14 adapted to accommodate a single absorber in the form of a ball 12.
  • Figure 6 also shows how the recess 14 may be formed.
  • the recess is formed initially by cutting-out a portion of the sole by drilling into the sole, for example.
  • the cut-out is formed in a front portion of the sole in the area that is adapted to support the ball of the foot during use.
  • the cut-out 24 is substantially circular in shape.
  • the dimensions of the cut-out are such that when the absorber 10 is positioned in the recess, the recess is large enough to accommodate the change in shape of the absorber 10 when it is in its deflected/compressed state.
  • the cut out extends to the inner sole 26 of the shoe and leaves the inner sole 26 intact.
  • the shoe has a diameter of approximately 5cm and a depth of approximately 15mm.
  • a layer of padding 18 may then be positioned within the recess covering the exposed portion of the inner sole.
  • the padding 18 is shaped to fit snuggly within the recess 14.
  • the padding 18 is shown in position in the shoe 21 in Figure 6.
  • the padding may be formed from any suitable material, and in this embodiment the padding has been formed from rubber from a mouse mat and is a few millimetres thick.
  • the padding should be sufficiently stiff to aid the inner sole in spreading the load applied by the energy absorbing member on the foot. It should also deflect a little plastically, providing a seating for the energy absorbing member. High density foams including plastic foams may be appropriate.
  • the shoe 30 comprises an outer layer 32 adapted to extend at least partially across the sole 4 in order to cover the absorber 10 and recess 14.
  • the outer layer 32 is particularly useful for retaining the absorber in place and for preventing dirt etc. from entering the recess.
