A footwear with a fluid which flows through integral chambers and passageways within the sole in which additional traction elements may be selectively and forcedly deployed and retracted. Valves on the footwear in combination with a control system, control the flow of the fluid allowing the user to choose between a range of traction deployment options to suit the needs of the user.

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 open space at least at a forefoot support area of the ground-engaging component, wherein the outer perimeter boundary rim is shaped such that the outer perimeter of the ground-engaging component tapers or curves inward moving from a forefoot support area to an arch support area, and wherein a narrowest dimension from a lateral side edge to a medial side edge of the outer perimeter boundary rim is located in a heel support area of the ground-engaging component; and (b) a support structure extending into or at least partially across the open space. The ground-engaging component may have a narrower width dimension in a central heel or rear heel support area than in the arch support area.

Various embodiments of a system and associated method for a micro-adjustable traction element are disclosed herein. The micro-adjustable traction element system includes an outsole for positioning along a substrate of a shoe. The outsole secures a traction element to the outsole while enabling positional micro-adjustment of the traction element along the outsole. In one embodiment of the micro-adjustable traction element system, for each traction element positioned along the outsole, the outsole includes a receiver element configured for variable positioning within a pocket of the outsole to receive the traction element.

In an anti-slipping device for a shoe sole having an anti-slipping or anti-sliding component such as nails or spikes which are not secured to the sole but are secured on support elements which can be overturned to be hidden in slots made on the sole itself, each overturning support element is hinged at its ends on cubic blocks which are anchored to the sole due to a mushroom-shaped coupling element which is molded in once piece to the cubic block itself, made of the same thermo-polyurethane material as the support elements and which is snap-fitted in its seat arranged in the sole next to the slot where the overturning support element is accommodated after the overturning, without interfering with the integrity of the sole itself and thus allowing the replacement thereof without difficulty. Also included is a mechanism for avoiding the accidental loss of the support element when walking.

The invention relates to a sole arrangement (10) for an anti-slid shoe (1). Said sole arrangement (10) comprises an upper and a lower sole member (20, 50) wherein the lower sole member (50) is vertically movable in relation to the upper sole member (20). Spike holding units (15) are arranged at the upper sole member (20) and are configured to hold spike members (8) extending in a vertical direction inside the sole arrangement (10). The sole arrangement (10) further comprises a locking system comprising spacing means (12) and a movable locking plate (30) arranged between the upper and lower sole members (20, 50), configured to control the vertical distance between the sole members (20, 50) to prevent the spike member (8) from protruding through the lower sole member (50). The spike holding unit (15) extends downwards through an opening (17) in the locking plate towards a spike opening (16) in the lower sole member (20).

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 wherein a rearmost extent of the outer perimeter boundary rim is located within one of: an arch support area or a forward heel support area of the ground-engaging component (and/or at these areas of an overall sole structure); and (b) a support structure extending from the outer perimeter boundary rim and into or at least partially across the open space.

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 open space at least at a forefoot support area of the ground-engaging component, wherein the outer perimeter boundary rim is shaped such that the outer perimeter of the ground-engaging component tapers or curves inward moving from a forefoot support area to an arch support area, and wherein a narrowest dimension from a lateral side edge to a medial side edge of the outer perimeter boundary rim is located in a heel support area of the ground-engaging component; and (b) a support structure extending into or at least partially across the open space. The ground-engaging component may have a narrower width dimension in a central heel or rear heel support area than in the arch support area.

The ground-engaging component may have a narrower width dimension in a central heel or rear heel support area than in the arch support area.

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; (b) an inner perimeter boundary rim that at least partially defines an inner perimeter of the ground-engaging component, wherein a first open space is defined between the outer perimeter boundary rim and the inner perimeter boundary rim, and wherein a second open space is defined between a lateral side portion of the inner perimeter boundary rim and a medial side portion of the inner perimeter boundary rim; and (c) a support structure extending from the outer perimeter boundary rim to the inner perimeter boundary rim and across the first open space.

A sole designed for attachment to an article of footwear, made of a hard polymer outsole connection plate affixed to a flexible polymer outsole that has a series of threaded imbed anchors housed therein for the attachment of various designs of interchangeable cleats. The cleats reside in detents formed on planar channels across the width of the outsole and extend above a series of tapered raised pads formed on the bottom face of the outsole.
