The heel counter structure includes a sole plate provided at least at the heel region of the shoe and having a peripheral portion. The peripheral portion is upraised along the heel region of the shoe so as to enclose the lower portion of the heel portion of the foot of the wearer. The heel structure also includes a pair of heel counter portions provided on the medial and lateral sides of the heel region of the shoe so as to sandwich the heel portion of the foot sideways. The heel counter portions are coupled to the peripheral portion of the sole plate at the lower ends of the heel counter portions so that the heel counter portions can tilt inwardly and outwardly independently of the sole plate. The heel counter portions are separated from the peripheral portion of the sole plate except the lower ends of the heel counter portions.

Heel counter structure for a shoe

A sole structurefor a shoe comprises an upper sheet portiondisposed on the upper side of the sole structure, and a plurality of curved sheet portions(-) that are provided on the lower surface of the upper sheet portion, that have downwardly convexedly curved portions-, respectively, and that are disposed side by side and partially overlapped with each other in the longitudinal direction. Each of the curved sheet portions-has a first end A (A-A) and a second end B (B-B) on the opposite sides of each of the downwardly convexedly curved portions-. The first end A of the curved sheet portionis located on the front side of the sole structureand fixed to the lower surface of the upper sheet portion. The second end B of the curved sheet portionis located on the rear side of the sole structureand fixed to the external surface of the adjacent curved sheet portion

Sole structure for a shoe

A sole structurefor a shoe comprises an upper platehaving a heel region and disposed on the upper side of the structure, a first C-shaped portionand a second C-shaped portioneach having a longitudinally flat, generally C-shape with an upwardly opening portionA,A, disposed alongside in the longitudinal direction under the upper plate, and each opening end of the upwardly opening portionsA,A directly fixed to the upper plate, and a connecting portioninterposed between and connecting the first and second C-shaped portions. The C-shaped portionsare formed of downwardly convexly curved surfacesand diagonally upwardly convexly curved surfaces, respectively, which extend diagonally upwardly from the downwardly convexly curved surfacestoward the upper plate

A sole structure for an athletic shoe includes a heel region and a forefoot region, a midsole of a soft elastic material including a midsole heel portion at the heel region, and an outsole of a harder material including an outsole heel portion at the heel region and an outsole forefoot portion that extends from the outsole heel portion to the forefoot region. The midsole heel portion has wavy corrugations on a lower surface thereof and a smooth plane on an upper surface thereof. The outsole heel portion includes a corrugated wavy plate with corrugations through its thickness, which are in phase with the wavy corrugations on the lower surface of the midsole heel portion.

Sole design and structure for athletic shoe

An athletic shoe sole structure includes a midsole body that extends from a heel region to a forefoot region of a shoe, and an outsole body that is disposed under the midsole body, extends from the heel region to the forefoot region of the shoe, and is formed of a harder material than the midsole body. A heel portion of the outsole body includes a corrugation. The sole structure further includes a lower midsole disposed under the heel portion of the outsole body, an outsole heel portion attached at a lower surface of the lower midsole, and cleats provided at a lower surface of the outsole body. The sole structure having only two layers with the outsole and the midsole decreases the weight of the shoe, simplifies a manufacturing process, and reduces a manufacturing cost.

A shoe sole structure includes an outsole that extends from a heel region to a forefoot region of a shoe, and a midsole that is disposed above the outsole and extends from the heel region to a midfoot region of the shoe. A heel portion of the outsole includes a corrugated portion. A heel portion of the midsole includes a corrugated portion, which corresponds in phase to the corrugated portion of the outsole. Cleats are provided at a bottom surface of the outsole. The corrugated portion on the outsole provides running stability. The sole structure having only two layers with the outsole and the midsole decreases the weight of the shoe, simplifies a manufacturing process, and reduces a manufacturing cost.

A midsole assembly for an athletic shoe comprising a midsole and a corrugated sheet. The midsole is formed of soft elastic material. The corrugated sheet is disposed in at least a heel portion of the midsole. Either or both amplitude and wavelength of wave configuration of said corrugated sheet are made different either or both between a front end portion and back end portion, and between an medial portion and lateral portion of said heel portion.

Athletic shoe midsole design and construction

A midsole assembly for an athletic shoe includes a midsole formed of soft elastic material, and a corrugated sheet disposed in at least a heel portion of the midsole. The amplitude of the wave configuration of the corrugated sheet is larger at the medial and lateral sides of the heel portion and smaller at the central portion between the medial and lateral sides. Alternatively, the wave phase of the corrugated sheet is offset by one half of a wave pitch between the medial and lateral sides.

A midsole assembly for an athletic shoe comprises an upper midsole,and a lower midsole,formed of soft elastic material, and a corrugated sheet 4 having a heel portion,formed with a corrugation. The corrugated sheet,is interposed between the upper and lower midsoles,. Upwardly and downwardly extending walls,and,are formed at the medial and lateral sides of the corrugated sheet,. Thereby, transverse or lateral deformation of the heel portion of the midsole,can be securely prevented and running stability can be further improved.
