Orthopedic Boot Or Shoe With Corrective Element Patents (Class 36/140)
  • Patent number: 6658766
    Abstract: A structural chassis includes a structural chassis and a foam chassis or sock liner sandwiched together to form an assembly that can be inserted into and substantially occupy a footbed of a shoe upper. Discrete sole elements are attached to a bottom side of the upper so as to expose certain portions of the bottom side therebetween. This absence of outsole material in those areas makes the upper collapsible about those areas since the outsole provides no support in those areas. Instead, the structure is provided by the chassis of the chassis, which is customized to the user's foot by placing one or more notches in strategic locations along the chassis where the foot naturally flexes. One such notch is located on the chassis in a position that allows the chassis to flex about a forward push-off axis of the foot that runs through the first and second MTP joints.

A third method step includes lifting the first foot and the device while applying full body weight to a second knee in order to place the first foot and the device on the first step adjacent to the second foot. Lifting the second foot and lifting the first foot and the device are achieved while the first and second knees are bent no more than an angle necessary to climb approximately half a step rise. The sequential foot lifting is repeated until the user has climbed the stairs. The device includes a foot securing portion for removably attaching it to only one of a user's feet.

  • Patent number: 5727335
    Abstract: Footware is made such that a thickness of a heel region from a sole upper surface to the ground is thinner at a backward portion than at a forward portion, whereby a line connecting a position on a lower surface of the sole under the head of the second metatarsus to a front end on a lower surface of the heel region of the sole is lifted at an angle with a horizontal line connecting a grounded rear end on the lower surface of the heel region to a front end thereof in a state where a weight is loaded to the human heel, and the backward portion of the heel region comprises an impact absorbing mechanism, whereby a level of the human heel which is in contact with a foot is depressed when loaded. Thus, the footwear protects a knee joint of a patient suffering from the osteoarthritis of the knee and enables them to easily walk.

  • Patent number: 5722186
    Abstract: An orthotic insert adapted to be placed within a shoe having an insole. The orthotic insert has a relatively rigid, resilient base member having a heel portion and an arch portion. The upper surface of the base member is contoured to fit the plantar surface of a person's foot, so as to position the foot in a generally desired angular orientation. At least one curvilinear ridge is formed on the lower surface of the base member, and extends continuously around the rearward end of the heel portion and along the arch portion on both sides of the longitudinal axis of the orthotic insert. The ridge has a sharp lower edge which projects downwardly from the lower surface of the base member for supporting the heel seat in the heel section above the insole when the orthotic insert is placed within the shoe. The lower edge of the ridge is adapted to have material incrementally removed therefrom so that the angular orientation of the foot can be adjusted to suit an individual person.

  • Patent number: 5572808
    Abstract: An orthopedic shoe insert for correcting the adduction of the large toe is disclosed. The insert comprises generally a foot bed-like rear foot shell whose front edge lies approximately below the ball of the large toe and a corrective lobe molded on the side for supporting and guiding the large toe. The inside surface of the corrective lobe is slightly curved in a concave manner. Stiffening ribs are molded externally into the transition region between the corrective lobe and the rear foot shell. The lower edge of the corrective lobe is curved upwardly in order not to interfere with the rolling motion when walking. Because of the shaping and the use of elastic thermoplastic material, the corrective lobe is swiveled inwardly when walking, thereby actively correcting the malpositioning of the large toe.

  • Patent number: 5327663
    Abstract: A corrective foot insole for sufferers of an uncompensated forefoot varus, more commonly known as flexible flat foot. The corrective insole has a forefoot and a midfoot portion. The forefoot portion of the insole provides a lift for the two interior toes a distance back to, but not including the heel of the foot. The midfoot portion provides an additional lift to the metatarsal by use of a support arch which is located on top of the forefoot portion. The corrective foot insole allows the midfoot to rotate into supination. The entire first metatarsal and two interior toes are lifted into a position to compensate for the forefoot varus, and this insole also maintains the normal alignment position, motion and function of the entire foot during use of the corrective foot insole while maintaining the heel of the foot in its normal position.

  • Patent number: 5282328
    Abstract: Custom molded foot beds position the feet in balanced positions. A balanced foot position represents a referenced neutral foot position compensated for an individual's particular lower body anatomy. The foot beds and the apparatus and method for making the foot beds produce a balanced position by applying forces to the foot. First forces move the foot toward the referenced neutral position by a first foam block located under the forefoot lateral column. A composite foam block produces a rolling force in the rear foot to move the subtalar joint toward alignment. Other forces provide anatomical compensation including forces that elevate the heel and cup fatty tissue around the heel. Other forces support the remainder of the foot in this balanced position.
