Definitions

  • a midsole for footwear comprising a main part extending substantially from the rear to the front of the footwear, and a damping insert positioned at the rear of the midsole, in a housing of the main part, the insert including:
  • the central portion has a thickness greater than the thickness of the intermediate portion
  • at least part of the peripheral portion has a thickness greater than the thickness of the intermediate portion
  • the main part of the midsole comprises a portion cooperating with the intermediate portion of the damping insert.
  • the insert also includes a peripheral portion intended to also damp the stresses when the user does not press his foot perpendicularly to the ground, but on the contrary obliquely.
  • the user when pressing again his foot at the end of run, may have to place it on the ground on the outer or lateral side of the shoe, in order to be able to move then in the opposite direction.
  • the user when playing badminton for example, the user, on a forward run to catch a drop shot, may have to place his foot on the ground from the back of the shoe, in order to be able to jerk rapidly forward.
  • the peripheral portion of the insert is provided to damp such motions that are peculiar to sports practice and to provide more comfort to the user in his classic and repetitive gestures related to the specific sport he is practicing.
  • the insert includes an intermediate portion disposed between the central portion and the peripheral portion, and which has a smaller thickness.
  • the peripheral portion forms in particular a hollow area between the central portion and the peripheral portion, intended to cooperate with the main part of the midsole. More specifically, the intermediate portion is intended to cooperate with a portion of the main part having a complementary shape.
  • the main part has in particular a housing in which the insert is positioned, for example from below or from beneath.
  • the housing can be a blind hole or a through housing.
  • the insert allows providing both vertical and oblique cushioning, that is to say axial, medial and/or lateral cushioning, while allowing integration with the main part of the midsole which cooperates with the insert via the intermediate portion thereof.
  • the insert is therefore not mechanically retained in the sole only by its upper and lower faces, but also by the intermediate portion which cooperates with a rear portion of the main part of the midsole.
  • the rear portion of the main part of the midsole is in particular positioned between the central portion and the peripheral portion of the insert, and therefore allows exerting holding stresses on the sides of the central and peripheral portions of the insert.
  • the rear portion of the main part ensures holding the insert in position in the midsole, and also allows partly dissociating the damping properties from the central portion and the peripheral portion of the insert.
  • the peripheral portion is exposed on the outside of the footwear.
  • part of the peripheral portion has a thickness greater than the thickness of the central portion.
  • the peripheral portion due to its positioning, generally has a smaller width than the central portion of the insert.
  • the peripheral portion is provided to have a greater thickness than the central portion, which thus allows having a peripheral portion with a greater volume providing sufficient cushioning despite its small width.
  • the peripheral portion of the insert extends on the lateral side of the footwear.
  • the midsole comprises a single lateral peripheral portion.
  • the peripheral portion extends on the rear and lateral side of the footwear, preferably continuously, and the damping insert is devoid of peripheral portion on the medial side of the footwear.
  • the midsole comprises a single rear peripheral portion and a single lateral peripheral portion, preferably continuously, that is to say a single peripheral portion extending both on the rear side and on the lateral side of the footwear.
  • Such one embodiment is more specifically intended for badminton or sports in which the user has to perform fast forward runs.
  • the insert according to the first embodiment thus includes a peripheral portion adapted to the areas where the user presses his foot on the ground during his sports practice. Particularly, the peripheral portion extends across the back and on the lateral side of the midsole, while the medial side does not include a peripheral portion of the insert. Such geometry thus promotes damping when the user presses again along the axis and toward the outside of his foot.
  • the damping insert comprises a material made of TPU, EVA or a foamed material and is preferably monobloc.
  • the peripheral portion extends, preferably only, on the lateral side of the footwear, and the damping insert is devoid of peripheral portion on the rear side and on the medial side of the footwear.
  • the midsole comprises a single lateral peripheral portion.
  • the main part being able to hold the insert via a bead cooperating with the intermediate portion, it is then possible to provide for an opening in the main part to expose the central portion, particularly the upper surface of the central portion of the insert.
  • the insert does not need to be held in the midsole by contact of the upper and lower surfaces: the groove formed by the intermediate portion between the main portion and the peripheral portion allows cooperation with a corresponding portion of the main part, which matches the shape of the intermediate portion and maintains the mechanical linking between the main part and the insert.
  • the intermediate portion and the portion of the main part which cooperates with the intermediate portion have complementary geometries.
  • the upper surface of the central portion of the insert is then no longer necessary to hold the insert in the midsole, but can on the contrary be exposed to the surface of the midsole to further improve the damping effect by avoiding thickness of the main part above the central portion of the insert.
  • the central portion extends from the lower surface of the midsole in contact with the outsole, up to the upper surface of the midsole in contact with the insole.
  • a sole for footwear comprising a midsole as described above is also proposed.
  • Figure 3 represents an exploded view of the sole illustrated in Figure 1;
  • Figure 12 represents a perspective view of the insert of the sole illustrated in Figure 10.
  • Figures 1 to 5 illustrate a first embodiment of a sole 1 for footwear according to the invention.
  • the sole 1 is for example designed for footwear intended for the practice of a sporting activity, in particular tennis.
  • the midsole 2 includes in particular a main part 6 and a damping insert 8 disposed in the rear part of the midsole 2.
  • the damping insert 8 aims at providing flexibility and cushioning to the sole 1, particularly at the level of the user's heel, while the main part 6 aims at providing some holding and comfort to the rest of the user's foot.
  • the housing 10 can be a blind hole or, as illustrated in the figures, a through hole, having a shape complementary to that of the insert 8, in particular to allow it to be held in the midsole 2.
  • the side wall 6b of the main part 6 can comprise a crenellated part, particularly on the rear part of the midsole 2, which is intended to cooperate with exposed parts of the damping insert 8, as described below.
  • the damping insert 8, or insert 8 has a lower surface 8a, side walls 8b and an upper surface 8c.
