  • the inner strap 44 then extends along the inside of the medial wall 16, around the upper portion of the inner boot liner 50 proximate the front liner edge 56, underneath the tongue 34 and through an inner eyelet 74 located on the lateral wall 18.
  • the inner strap 44 originates at the lateral side of the wearer's ankle, extends behind the wearer's Achilles tendon and wraps around the front of the wearer's ankle before proceeding through the inner eyelet 74.
  • the inner strap 44 may extend over the tongue 34 before being inserted through the inner eyelet 74 (see FIG. 9 and its associated discussion below for a more detailed description of this alternate embodiment).
  • the outer strap 46 extends from the strap seam 72 upwardly along the medial wall 16, over the upper portion of the inner boot liner 50, underneath the inner strap 44, through the inner boot strap loop 62 and through an outer eyelet 76 located on the lateral wall 18 proximate the inner eyelet 74. From the perspective of the wearer, the outer strap 44 begins at the arch of the wearer's foot proximate the wearer's heel and extends up and directly over the wearer's ankle mortise before proceeding through the outer eyelet 76.
  • This configuration allows the inner and outer straps 44, 46 to secure the wearer's foot against the heel 22 of the shoe 10 and prevent the wearer's foot from sliding forward inside the shoe 10, thereby supporting the ankle's lateral ligaments and inhibiting the wearer's ankle from inverting.
  • the inner and outer straps 44, 46 are fed through the inner and outer eyelets 74, 76, respectively, enabling the inner and outer straps 44, 46 to cooperate with the buckle 48 to secure the wearer's foot and ankle inside the shoe 10.

  • the inner strap 44 is then fed back through the buckle 48 via the upper buckle slot 48b, is cinched tight and is then fastened to itself (i.e., by attaching the inner strap hook patch 44a to the inner strap loop patch 44b).
  • the outer strap 46 is positionable so as to be crossed over the instep of the shoe 10, fed through the buckle 48 via the upper buckle slot 48b and cinched tight.
  • the outer strap 46 is then wrapped over the buckle 48 and is fastened to itself (i.e., by attaching the outer strap hook patch 46a to the outer strap loop patch 46b).
  • the outer strap 46 may be fastened to the inner strap 44 (i.e., by attaching the outer strap hook patch 46a to the loop patch 44c on the inner strap 44).
  • the outer strap hook patch 46a may be attached to both the outer strap loop patch 46b and the inner strap loop patch 44c simultaneously.
  • the shoe 10 also includes anterior and posterior lateral bumper supports 78, 80 located on the lateral side of the sole 14 (i.e., proximate the lateral wall 18).
  • the anterior lateral bumper support 78 is located proximate the toe 20 of the shoe 10, while the posterior lateral bumper support 80 is located proximate the heel 22 of the shoe 10.
  • the lateral bumper supports 78, 80 help inhibit ankle inversion by providing a wider surface area to the sole 14 of the shoe 10, thereby increasing the leverage the shoe 10 has against inversion during use.
  • the lateral bumper supports 78, 80 provide support to the wearer's ankle in addition to that of the inner and outer straps 44, 46 and the inner boot liner 50.
  • the lateral bumper supports 78, 80 are integrally molded to the sole 14 of the shoe 10 and are generally constructed in the manner discussed in U.S. Patent No. 6,775,929 B2, the disclosure of which is incorporated by reference herein in its entirety. Additionally, the lateral bumper supports 78, 80 are made of a rubber material that is softer and has a lower hardness than the material of the sole 14. For example, in one embodiment, the outsole 14b of the sole 14 has a durometer within the range of 59A to 65A, while the lateral bumper supports 78, 80 have (.urometers within the range of 52A to 58A. The softer material of the lateral bumper supports 78, 80 improves their shock absorption characteristics, thereby providing a greater cushioning effect for the shoe 10 when the wearer's foot takes off from and lands on the ground.
  • the lateral bumper supports 78, 80 are slightly elevated from the ground by a distance D in comparison with the bottom of the sole 14 of the shoe 10.
  • the distance D between the bottom of the elevated lateral support bumpers 78, 80 and the bottom of the sole 14 is in a range from about 1 mm to about 3 mm.
  • the elevated nature of the lateral bumper supports 78, 80 helps decrease the amount of contact they make with the ground during ordinary use of the shoe 10, which helps reduce the wear experienced by the lateral bumper supports 78, 80 during such use.
  • FIG. 8 shows one method of wearing the shoe 10.
  • the wearer places one finger in the front finger loop 60 and a second finger in the heel finger loop 42.
  • the wearer then pulls the front and heel finger loops 60, 42 away from each other, thereby stretching the front ankle liner edge 56 away from the rear liner edge 58.
  • the wearer then places his or her foot into the opening 40 of the shoe 10 and between the front liner edge 56 and the rear liner edge 58.
  • the wearer may then pull upwardly on the front and heel finger loops 60, 42 to facilitate full insertion of his or her foot into the inner boot liner 50.
  • the wearer may simply hold the lateral edges of the opening 40 wide while placing his or her foot therein and use the front and heel finger loops 60, 42 to straighten the inner boot liner 50 against the wearer's foot in case the inner boot liner 50 buckles (i.e., gets "bunched up") in the process.
  • the wearer may then secure the shoe to his or her foot by tightening and tying the shoelace 32 and fastening the inner and outer straps 44, 46 in the manner described above.
  • the lateral bumper supports 78, 80 can be detachable and reattachable in reference to the sole 14 of the shoe 10 (see detached posterior lateral bumper support 80 in FIG. 6).
  • This embodiment allows the lateral bumper supports 78, 80 to be removed from the shoe 10 if they are not deemed desirable for a particular application, or replaced if they become damaged as a result of excessive wear.
  • the lateral bumper supports 78, 80 are attached and detached from the sole 14 using a male-female releasable coupling mechanism or a releasable detent clip.
  • the lateral bumper supports 78, 80 are positioned lower, so as to be flush with bottom surface of the sole 14 in order to increase the traction the shoe 10 has with the ground surface.
  • the lateral bumper supports 78, 80 are height adjustable, thereby allowing the wearer to choose whether or not he/she wishes to have increased traction with the ground.
  • FIG. 9 illustrates a second embodiment of the present invention.
