Abstract

It is described an adaptable shoe or footwear comprising cut pieces made of flexible material joined to side of the sole of shoe with temporary fixation means. The shoe is suitable for feet with bunions.

Description

  • This invention describes an adaptable shoe or footwear with cut pieces made of flexible material joined to the side of the sole of the shoe with temporary fixation means.
    • State of the art
  • Shoes are manufactured to permanently join the instep of the shoe to the sole of the shoe. For instance, both elements may be glued or stitched. In general, insteps and soles are joined at the upper part of the sole. In this way, the shoe adapts perfectly to users' feet.
  • There are morphological differences in the feet of different users and even between the left and right foot of the same user. In these cases, a shoe that is too tight may cause injuries to users, owing to the morphological irregularities of feet. It is even worse if a user has bunions and/or calluses.
  • The state of the art describes different adaptable shoes, for instance, FR2580475 which describes a shoe with changing adjustment. None of them describes shoes appropriate for feet with bunions.
  • The state of the art describes different shoes appropriate for feet with bunions or calluses. The technical elements used in them are patches or perforations in the instep of the shoe to avoid contact of the foot with the shoe; but the state of the art does not describe shoes with soles temporarily joined to the instep.
    • Object of the invention
  • This invention provides a solution for feet with bunions and calluses.
  • The inventors created a shoe that comprises a sole with a plurality of holes located on the side of the sole and the flexibly cut piece has holes at the ends that are fixed to the sole by means of temporary fixation.
  • The means of temporary fixation allow the shoe to adapt to the irregularities of feet, by adapting the cut piece to the foot without pressure, thus creating a dead volume between the foot and the shoe. The means of adjustment on the side of the sole avoid the irregularities of the foot, bunions and calluses. If the instep and sole were joined on the upper part of the sole, it would not be possible to avoid the bunions.
  • Furthermore, the dead volumes leave room for patches or gauze to further protect the bunions.
  • In a particular mode, the means of temporary fixation are adhesive tape, velcro® tape or rods introduced through the holes of the cut piece and of the sole.
  • In the preferred mode, the means of temporary fixation are screws and, also, the holes of the flexible cut piece are elongated. The temporary fixation of the screw is done by hand. The flexible piece is provisionally joined to the sole, the piece is adapted to the shape of the foot and, finally, the permanent fixation of the flexible piece to the sole is done with a screwdriver. The adjustment of the flexible piece may be done by folding the flexible piece or by moving the cut piece along the elongated hole.
  • In another preferred mode, the screw heads are oversized. The screws facilitate the adjustment/dismounting operation.
  • Furthermore, the invention describes a kit that includes a shoe and a screwdriver.
    • Description of the drawings
  • Figures 1 and 2 show two perspectives of the shoe.
    • Detailed description
  • The term "flexible" means any material that may be folded.
  • The term "temporary fixation" means fixation without using tools, in other words, manually done.
  • The term "permanent fixation" means fixation using tools.
  • The instep of the shoe or footwear is made of a cut piece (3) manufactured in flexible material with a plurality of holes (9). The sole of the shoe (1) has a plurality of holes (5) on the side. The flexible piece (3) is joined to the sole of the shoe by means of temporary fixation means which will be later permanently fixed.
  • The means of temporary fixation are double-sided adhesive strips or velcro® tape (8). The strips are placed inside the flexible piece (3a) and on the side of the sole (3b). The temporary fixation may also be done by using screws or rods (4) introduced in the holes of the sole (5). After fitting the cut piece (3) to the side of the sole temporarily, the cut piece (3) is adjusted to the shape of the foot. The adjustment of the cut piece (3) to the foot is done by folding the cut piece. If the hole (9) has an elongated shape, the adjustment is done by moving the flexible strip (3) along the hole (9).
  • The permanent fixation of the shoe is done with screws (4) screwed with a screwdriver or another machine. The permanent fixation with screws is optimised with the use of pegs (6).
  • The adjustment of the cut piece (3) creates a dead volume avoiding contact of the shoe with the foot. Furthermore, the dead volume is appropriate for placing gauze to protect bunions.
  • The shoe does not touch the bunions and/or calluses and ensures fixation of the foot to the shoe.
  • The adjustment screws may be of any kind; in a preferred mode, screws with over-sized heads are used, in other words, the diameter of the screw head is far bigger than the screw rod. Furthermore, the screws have ornamental motifs for aesthetic purposes. Screws that are star-shaped facilitate manual adjustment.
  • The shoe may contain insoles (10), heel (2) or other ornamental motifs (E1-E2).
  • The shoe is sold in a kit that contains a screwdriver.
