Ground-engaging components for articles of footwear include: (a) an outer perimeter boundary rim that at least partially defines an outer perimeter of the ground-engaging component, wherein the outer perimeter boundary rim defines an upper-facing surface and a ground-facing surface opposite the upper-facing surface, wherein the outer perimeter boundary rim defines an open space at least at a forefoot support area of the ground-engaging component; and (b) a matrix structure extending from the outer perimeter boundary rim (e.g., the ground-facing surface and/or the upper-facing surface) and across the open space at least at the forefoot support area to define an open cellular construction with plural open cells across the open space at least at the forefoot support area, wherein a plurality (e.g., at least a majority) of the open cells have curved perimeters with no distinct corners.

A reversed arch pair of shoes for enhanced athletic performance, reduced injury, and pain reduction. The right shoe has an arch on the right side, and an extended toebox that extends forward and rightward, the toebox extending forward a distance beyond an area that supports the right big toe. The left shoe has an arch on the left side, and an extended toebox that extends forward and leftward, the toebox extending forward a distance beyond an area that supports the left big toe. The shoes can help people recovering from knee and hip replacements, and can also alleviate conditions which are exacerbated by walking or running. The shoe can also release pressure on the back by improving the wearer's posture, thereby resulting in less back pain. The shoes can help any athlete who wishes to run faster, jump higher, and accelerate more rapidly, thereby providing an advantage in any sport.

A plurality of orthotic systems are provided. One bi-layer system is constructed from a single sheet of fabric that is molded into two layers. One tri-layer system includes a base layer; a mid-layer; and an upper layer. The upper layer is joined to the mid-layer and the mid-layer is joined to the base layer. The coupling of the base layer, the mid-layer and the upper layer create a rear spring section, a mid-spring section and a front spring section in which the upper layer is suspended over the mid-layer and the heel portion is suspended on the proximal heel end of the base layer.

A sole structure for an article of footwear includes a heel region, a forefoot region, and a midfoot region disposed between the heel region and the forefoot region. The sole structure also includes a fluid-filled chamber including a first barrier layer cooperating with a second barrier layer to define a first segment extending along a medial side of the sole structure within the heel region, a second segment extending from the medial side in the forefoot region to a lateral side in the heel region and along a lateral side of the sole structure within the heel region, and a web area disposed between and connecting the first segment and the second segment. The first barrier layer being attached to the second barrier layer within the web area.

The present invention provides for a sole structure for a shoe having a bottom surface, comprising, inter alia, a forefoot sole portion, arranged towards a distal end along a longitudinal central axis of said sole structure; a rearfoot sole portion, arranged towards a proximal end along said longitudinal central axis of said sole structure; and an articulation portion, adapted to operably couple said forefoot sole portion and said rearfoot sole portion, so as to allow relative movement between said forefoot sole portion and said rearfoot sole portion matching the triplanar movement provided by the midtarsal joint in any one of the frontal, sagittal and transverse plane of the foot, during use.
