Patent Description:
Proprioception refers to the ability to know where a body part is located in space and to recognize movements of body parts (such as fingers and toes, feet and hands, legs and arms). Kinesthesia is a related term, and refers to the sensation by which position, weight, muscle tension and movement are perceived. In some of the medical literature, proprioception refers to the conscious and unconscious appreciation of joint position, while kinesthesia refers to the sensation of joint velocity and acceleration. Proprioception is often used inter- changeably with kinesthesia, and herein as well, the terms will beused interchangeably.

<CIT> describes novel proprioceptive and kinesthetic exercise apparatus, which provides significant advantages over other prior art apparatus, such as tilt boards or shoes with a single protrusion. The apparatus includes two bulbous protrusions protruding from the underside of footwear, instead of the single ball of the prior art boards and shoes. One of the protuberances is positioned more posteriorly than the other protuberance. The extra protrusion may significantly increase the possibilities and enable walking and accelerate and improve the results of proprioceptive and kinesthetic treatment plans.

<CIT> describes a footwear assembly including a sole, and a map formed on the sole. The map including markings that define an orientation and position for mounting an item on to a bottom surface of the sole.

The invention relates to a footwear as specified in appended independent claim <NUM> and to a method method for anterior, posterior shift, medial shift, and/or lateral shift of a protuberance of a footwear as specified in appended independent claim <NUM>. Additional embodiments of the invention are disclosed in the dependent claims.

According to the present invention there is provided footwear for training, developing and enhancing proprioceptive and kinesthetic skills and neuromuscular control. The footwear includes one or more bulbous protrusions (protuberance) protruding from the underside of the footwear. In some embodiments, one of the protuberances is positioned more posteriorly than the other protuberance. These bulbous protrusions (protuberances) are also referred to as proprioceptive elements. In some embodiments, the outsole of the footwear comprises a visible outsole map.

The outsole map comprises one or more coordinate systems of which at least one is an anterior coordinate system and at least one is a posterior coordinate system. Coordinates of the coordinate system indicate a plurality of reference point for positioning a protuberance in respect to the outsole map. In some embodiments, a plurality of reference points is joined to form a line.

The terms "reference point" and "coordinate" are used interchangeably herein and refer to points on an outsole map with which a protuberance coordinate system is aligned.

In some embodiments, the footwear is configured to receive a foot of a human. In some embodiments, and as explained in greater detail herein, the protuberance is configured to align with an outsole map in accordance with a set of parameters specific to the user of the footwear. Once the protuberance is aligned with the outsole map and the footwear worn by the user placed on the ground, the position of the protuberance in respect to the outsole defines a spatial orientation of the foot of the user in respect to the surface of the ground.

In some embodiments, at least one coordinate system (the anterior coordinate system, posterior coordinate system, protuberance coordinate system) has parallel longitudinal alignment lines.

The protuberance <NUM> comprises a plurality sets of pointers, such as, for example, the four sets <NUM>, <NUM>, <NUM>, and <NUM>, as depicted in <FIG>.

For example, in some embodiments, one or more of the sets <NUM>/<NUM>/<NUM>/<NUM> are configured for alignment of the protuberance <NUM> with a portion of the outsole map <NUM> anterior in relation to an anterior rail midline. For example, in some embodiments, one or more of the sets <NUM>/<NUM>/<NUM>/<NUM> are configured for alignment of the protuberance <NUM> with a portion of the outsole map <NUM> posterior in relation to the anterior rail midline.

In some embodiments, the one or more sets <NUM>/<NUM>/<NUM>/<NUM> which are configured to align with the portion of the anterior outsole map. in some embodiments, alignment of the protuberance <NUM> places the protuberance center <NUM> either posterior or anterior to an anterior rail midline of the outsole <NUM>. In some embodiments, one or more sets <NUM>/<NUM>/<NUM>/<NUM> are marked P and are configured to align with the outsole map <NUM> such that the protuberance center <NUM> is positioned in a portion of the outsole map <NUM> which is posterior in relation to the anterior rail midline. In some embodiments, one or more sets <NUM>/<NUM>/<NUM>/<NUM> are marked A and are configured to align with the outsole map <NUM> such that the protuberance center <NUM> is positioned in a portion of the outsole map <NUM> which is anterior in relation to the anterior rail midline.
