  • Patent number: 9119436
    Abstract: A running shoe design focused on the heel section of running shoes used in, for example, T2 transition phase of the sport of triathlon. The heel reclines to facilitate the insertion of the foot without use of hands or need to bend in any way. Straps partially on the heel sides, kept at bay from premature contact with attachment pads on the forward portion of the running shoe, are kept away, and may also be kept later from premature contact by wire guides. Upon foot insertion, these straps, one on each side of the foot, are guided and securely affixed into place, for example, by a pressure movement of the opposite foot of the athlete.

  • Patent number: 8371045
    Abstract: In one embodiment, a hiking boot attachment is provided that assists in the descent of slopes. The hiking boot attachment includes a platform that engages the underside of a mid-portion of a sole of a hiking boot, in a region under a ball of a hiker's foot. A strap system is attached to the platform and secures the platform to the hiking boot. Further, one or more supports are secured to the platform. The one or more supports each have a portion that extends downward from a bottom face of the platform to engage the ground and lift the platform above the ground. This may reduce incline of the hiking boot when descending a slope. The portions of the one or more supports that engage the ground deliver downward force to regions of ground disposed to lateral sides of the hiking boot, to promote stability.

    Abstract: A harness for a snowshoe has straps, buckles and strap slip connections configured such that a single pull will snug the harness down to the boot, both at the toe and at the top of the arch, firmly engaging over the shoe or boot. The straps, which may be formed as a single strap, extend up from one side of the toe end of a footbed secured to the snowshoe, and pass through loops and buckles of the harness assembly in such a way that the ends of the straps, or a loop of the single strap can be pulled from between the buckles to tighten the harness at toe and arch areas simultaneously. Mechanical advantage preferably is provided at the toe end, by the strap looping back once before it reaches the buckle. The strap or straps are arranged and connected such that a flexible harness shell that extends up from one side of the footbed “floats” in position, accommodating a wide range of shoe or boot sizes.
