A midsole includes an upper layer and a lower layer made of a foamed material; the upper layer is a low-hardness foamed material; the lower layer is a high-hardness foamed material; the low-hardness foamed material of the upper layer is a low-hardness, high-resilience material that has a higher specific gravity than the high-hardness foamed material, that has a low hardness that is lower than the hardness of the high-hardness foamed material, and that has a higher speed at which to recover to an original shape after being deformed than that of the high-hardness foamed material.

The invention provides a shoe (1) with a sole providing a dynamic foot arch support, the shoe comprising a rubber outsole (9) and an upper (10), the shoe further comprises a midsole (2), the midsole comprising a harder elastic material (4), a softer elastic material (5), wherein the harder elastic material has elastic hardness in a range 1.3 to 3 times higher than the softer elastic material. The shoe is distinguished in that the harder elastic material is arranged in a band (3) inside the periphery of the midsole, wherein the softer elastic material (5) is arranged in the midsole inside the band of the harder elastic material, and the shoe further comprises: a support structure (8) arranged below the softer elastic material in direction medial to lateral and positioned from vertically below to 4 cm in front of the naviculare bone center of a typical user with feet fitting the shoe size, wherein the support structure has higher elastic hardness than the harder elastic material, with a larger vertical dimension medial compared to lateral as seen with the shoe standing on a horizontal surface, providing increased support under the medial side of the foot arch compared to the lateral side of the foot arch.

A sole structure for an article of footwear having a heel region, a mid-foot region, a forefoot region, an interior region, and a peripheral region. The sole structure including a bladder having a chamber including an arcuate segment extending around the heel region, a first segment extending along the peripheral region on a medial side of the sole structure from the arcuate segment to a first terminal end in the forefoot region, and a second segment spaced apart from the first segment across a width of the sole structure and extending along the peripheral region on a lateral side of the sole structure from the arcuate segment to a second terminal end in the forefoot region. A peripheral outsole extends along the chamber and a first cushion is disposed between the first segment and the second segment and is exposed through an opening of the peripheral outsole.

A sole structure for a shoe that can secure cushioning properties and obtain a ground surface information is disclosed. The sole structure includes a first midsole having a plurality of first protrusions on a foot-sole-contact side, an outsole having a plurality of second protrusions on a ground surface side, and a second midsole disposed at a part of a region between the first midsole and the outsole and having a lower compressive rigidity than the first midsole. At least a part of the plurality of first protrusions of the first midsole is located at a position corresponding vertically to at least a part of the plurality of second protrusions of the outsole.

A method of forming a plate for an article of footwear is disclosed. The method includes applying a first strand portion to a base layer including positioning adjacent segments of the first strand portion to form a first layer on the base layer. The adjacent segments of the first strand portion having a greater density across a width of the plate between a medial side and a lateral side at a forefoot region of the plate than at a midfoot region of the plate and at a heel region of the plate. The method also includes applying at least one of heat and pressure to the first strand portion and to the base layer to conform the first strand portion and the base layer to a predetermined shape.

An athletic shoe extending between toe (1) and heel (3) and comprising upper (5) attached to outsole (7) via comfort sole (9). According to the invention, the athletic shoe comprises shell (13) make of plastic or composite material, inserted between upper (5) and comfort sole (9) and to which it is attached at heel (1).

A sole structure for an article of footwear comprises a midsole body having a proximal surface and a distal surface. Proprioceptive elements may extend in the hole in the midsole body, and translate toward the proximal surface in the holes upon a force directed along a central axis of the hole at a distal end of the proprioceptive elements. In various embodiments, the holes may angle relative to vertical from the proximal surface to the distal surface, the holes may be defined by perforations and the proprioceptive elements may be integral portions of the midsole body, or the midsole body may have a plurality of annular holes at the proximal surface, and a plurality of annular recesses in the distal surface, and a plurality of proprioceptive elements, each centered in a different annular hole of the plurality of annular holes. Methods of manufacturing articles of footwear are described.

A shoe sole member formed by a foam includes cells having a certain size and being excellent in transparency in order to provide a shoe sole member being lightweight and excellent cushioning properties while having transparency.

A sole structure includes a foam element extending from a forefoot region to a heel region. A lower surface of the foam element includes a recess formed in the forefoot region. The sole structure also includes a posterior cushioning arrangement extending along a peripheral region of the sole structure from a heel region to a mid-foot region, and an anterior cushioning arrangement disposed in the recess of the foam element. The anterior cushioning arrangement has a proximal end adjacent to the lower surface of the foam element and a distal end formed on an opposite side of the anterior cushioning arrangement than the proximal end. The anterior cushioning arrangement includes at least one medial bladder proximate to a medial side of the sole structure and at least one lateral bladder proximate to a lateral side of the sole structure.

A sole for a shoe is provided comprising at least two reinforcing members extending at least in a front half of the sole, and at least two blade members extending at least in the front half of the sole. The reinforcing members define a first layer within the sole, and the blade members define a second layer in the sole, wherein the first layer and the second layer are at least partially displaced from one another in a vertical direction.
