Footwear includes a footbed portion including a support region. The support region includes an upper surface-side projection portion forming region having a plurality of upper surface-side projection portions. A maximum outer dimension in a cross-section orthogonal to a projecting direction of each of the plurality of upper surface-side projection portions is not greater than 3.0 mm. A projection length of each of the plurality of upper surface-side projection portions is not less than 4.0 mm and not greater than 13.0 mm, and an arrangement density of the plurality of upper surface-side projection portions in the upper surface-side projection portion forming region is not less than 10% and not greater than 100% in terms of an area ratio. An elastic modulus of a material forming the plurality of upper surface-side projection portions is not less than 0.1 MPa and not greater than 100 MPa.

Variable-density soles for articles of footwear and methods for constructing said soles are provided herein. In one embodiment, a variable-density sole for a footwear article comprises a first layer comprising a first density coupled to a bottom surface of an upper of the article of footwear; and a second layer comprising a second density greater than the density of the first layer, wherein the first layer is physically coupled to the second layer forming an interface between the layers. In this way, comfort of the article of footwear may be increased while decreasing the weight of the article of footwear. Further, forming the variable-density sole includes directly molding the first layer to a strobel board, stitching the strobel board to an upper, and injecting the second layer to the upper with the strobel board and the first layer. In this way, the production of a footwear article is simplified.

An article of footwear has a sole structure with multiple components. The sole structure includes a midsole member, an outsole member and an exterior support member. The midsole member and the outsole member have corresponding grooves. The exterior support member provides reinforcement for the midsole member. The outsole member includes a plurality of bristle members.

A shoe insole with an upper surface covered with numerous, small elastomer nodules with outstanding non-slip, gripping properties that grip and cushion the foot, to eliminate movement or slippage of the foot inside a shoe and thereby help wearers avoid foot or toe injury when playing sports.

A shoe includes a sole, an upper, and a welt. The sole and upper define a seam. The welt overlies the seam. The sole includes flex grooves. The upper includes perforations. The welt includes flex slits.

A three-layered shoe construction having an outsole with a first section located in the arch portion and extending into the proximal side of the forefoot and hind foot areas, and a second section located in the remainder of the outsole, the first section including a plurality of horizontal grooves, the second section including a plurality of small and elongated apertures, the outsole including first and second angled grooves extending across the outsole, the outsole having a first cavity on its interior face; a dual density midsole having a first density in the forefoot area and a second density in the hind foot area, the second density being greater than the first density, the midsole having a second cavity on its proximal face; and an insole having a top face including a plurality of raised projections. The specific construction associated with the three-layered shoe enhances flexibility, cushioning, and breathability.

A sole structure includes a first support extending along a first axis transverse to a ground-engaging surface of the sole structure and having a first outer sheath including a first sheath material and a first core including a first core material. The sole structure further includes a second support extending along a second axis transverse to the ground-engaging surface of the sole structure and having a second outer sheath including a second sheath material and a second core including a second core material.
