Definitions

  • the present invention relates to a sole and footwear comprising said sole. More specifically, it relates to a sole apt to improve walking, and to footwear comprising said sole, thus made more comfortable and performing.
  • footwear that includes particularly rigid soles that make the various stages of walking uncomfortable.
  • soles can be made of softer materials, but these give less support to the foot.
  • the purpose of the invention is to obviate the aforementioned drawbacks and others by providing a sole, and consequently a footwear comprising said sole, that act on the foot with both a supportive action and facilitating foot flexion.
  • a further purpose of the invention is to provide a sole and footwear that is cost-effective while providing comfort and high performance.
  • said sole includes a toe, a middle portion, and a back edge, so as to define a front portion between the toe and the middle portion, and a back portion between the middle portion and the back edge.
  • the sole has a contact surface with the ground.
  • a first longitudinal groove and a second longitudinal groove are made on the contact surface, which develop from the toe to the middle portion of the sole.
  • a right front portion, a middle front portion and a left front portion are identified on the contact surface of the sole in addition to the rear portion.
  • the flexibility of the front portion of the sole is improved; in particular, this flexibility is provided in the longitudinal direction.
  • the rear portion of the sole not being affected by the longitudinal grooves, ensures full heel support.
  • the first longitudinal groove and the second longitudinal groove have an arcuate profile and are arranged symmetrical to each other, thus assisting any torsional movements of the foot.
  • a front transverse groove, a middle transverse groove, and a rear transverse groove are made on the contact surface, so that in the front portion of the sole, a front part, a first middle part, a second middle part, and a rear part can be identified.
  • the front transverse groove, center transverse groove, and rear transverse groove can have a straight profile and be parallel to each other, so as to accommodate the bending motion of the sole itself.
  • the sole can flex naturally and analogously to the rolling of the foot during walking.
  • additional grooves can be made, positioned anteriorly and/or posteriorly to the three transverse grooves front, middle and rear, so as to provide more flexibility should the material used or the structure of the sole itself require it.
  • a central element having a rough surface is included in the sole, so as to improve the grip of the sole itself on the ground.
  • the center element may be arranged in the first middle part and the second middle part of the sole.
  • the center element may be substantially quadrangular in shape, so as to extend longitudinally and increase the grip surface.
  • the central element may be defined anteriorly by the front transverse groove, posteriorly by the rear transverse groove, and laterally by a right and a left groove, respectively.
  • the right groove and the left groove can be curved and symmetrical to each other along a longitudinal axis, so as to make a central element with a perimeter edge having a similar course to the edge of the sole, so as to provide more grip.
  • the central element is made of a different material from that of the remaining part of the sole, in order to obtain on the sole parts with peculiar characteristics according to their respective different functions.
  • the back portion, the right front portion, the center front portion, and the left front portion can be made of at least two different materials.
  • the central element can be crossed by the central transverse groove, so as to improve the flexibility of the central element itself.
  • fig. 1 is a schematic view from above of a sole, according to the invention.
  • 10 denotes a sole suitable for placement in a shoe to impart comfort and high performance.
  • the sole 10 is made of rubber, but may alternatively consist of other plastic or natural materials, such as leather.
  • a first longitudinal groove 12 and a second longitudinal groove 14 are made in the sole 10, particularly on the surface that contacts the ground, and these are carried substantially from just below the toe of the sole 10 to its middle part.
  • the first longitudinal groove 12 and the second longitudinal groove 14 have an arcuate profile and are arranged symmetrical to each other.
  • sole 10 it is, thus, possible to identify a single posterior portion 16 on which the heel rests, while anteriorly the sole is divided by the first longitudinal furrow 12 and the second longitudinal furrow 14 into a right anterior portion 18, a middle anterior portion 20 and a left anterior portion 22.
  • the first longitudinal groove 12 and the second longitudinal groove 14 provide some flexibility to the front portion of the sole; in particular, this flexibility is provided in the longitudinal direction.
  • the right front portion 18, the middle front portion 20, and the left front portion 22 can flex more easily than each other due to the presence of the longitudinal grooves 12, 14.
  • This flexibility in the longitudinal direction allows the foot to be able to rest more comfortably and naturally on the ground, allowing a kind of minimal rotation of the foot around a longitudinal axis of the shoe.
  • the support of the sole, and thus of the foot, on the ground can thus occur evenly from left to right or right to left, respecting the normal roll of the foot during walking.
  • the rear portion 16 of the sole being unaffected by the first longitudinal groove 12 and the second longitudinal groove 14, ensures full heel support, both when the foot is in motion and when it is resting on the ground.
  • a front transverse groove 24 In the front portion of sole 10, particularly on the surface that contacts the ground, there are, in addition, a front transverse groove 24, a middle transverse groove 26, and a rear transverse groove 28, all of which run from the right edge to the left edge of sole 10.
  • the front transverse groove 24, the middle transverse groove 26, and the rear transverse groove 28 all have a straight profile and are parallel to each other.
  • the front portion of sole 10 is thus also divided transversely by the three transverse grooves 24, 26, 28.
  • the transverse arrangement of the three transverse grooves 24, 26, 28 gives the sole 10, excellent flexibility properties even in the transverse direction.
  • first central part 34 and the second central part 35 arranged between the front transverse groove 24 and the rear transverse groove 28, are recreated right at the forefoot, specifically the part of the foot that supports the foot itself in its lifting during walking.
  • the flexion of the forefoot during walking is thus facilitated and a kind of natural pushing action is created, such that the blood circulation of the foot is improved.
  • a central element 38 is defined which is basically quadrangular in shape, being laterally circumscribed by a right groove 40 and a left groove 42.
  • central element 38 extends exactly from anterior transverse groove 24 to posterior transverse groove 28 and is crossed by central transverse groove 26 so that it is longitudinally flexible.
  • Central element 38 has a rough surface that gives the sole special grip on the ground. Notably, again, central element 38 is located precisely at the part of the foot (forefoot) that must provide adherence to the ground to give support in the lifting phase of the entire foot.
  • the central element 38 is made of a different material than the remaining part of the sole, possibly with a higher coefficient of adherence.
  • the rear portion 16 (even partially), the right front portion 18, the center front portion 20, and the left front portion 22 may be made of two or more different materials, so as to have different elastic properties depending on the functions of the different areas of the sole.
  • additional grooves can be made, positioned anteriorly and/or posteriorly to the three transverse grooves front, middle and rear, so as to provide more flexibility should the material used or the structure of the sole itself require it.
