A messaging apparatus for wearable items. The messaging apparatus may comprise a light source, at least one sensor to detect an event, and a controller to control the flashing of the light source in response to the detection of the event. The controlling of the flashing of the light source may generate at least one visible element that is visible to a viewer. Further, the light source may not be adapted in the form of the at least one visible element, but rather, the controlled flashing of the light source may be in the form of the at least one visible element.

A track and field shoe can include an upper and a sole structure. The upper includes a medial side portion, a lateral side portion, and a toe box portion. The sole structure is attached to the upper and includes a spike plate. The spike plate has an anterior portion, a posterior portion, a plurality of spikes, and a plurality of rails. The spikes extend in an inferior direction from the anterior portion of the spike plate and are configured for engaging a track surface. The rails extend in a superior direction from the anterior portion of the spike plate and extend over an exterior surface of the toe box portion of the upper, and the rails comprise longitudinal axes that extend in a superior/inferior direction.

An outer sole for a footwear including a base extending from a heel portion, through a midfoot portion, to a ball portion of the footwear, a plurality of cleats disposed on the base throughout the heel, midfoot, and ball portions of the footwear, and a plurality of interconnecting portions extending from each of the cleats and extending across a portion of the base, at least one of the interconnecting portions being connected to an adjacent cleat, where the cleats and the interconnecting portions include soft curves configured to avoid debris from accumulating on the sole.

An article of footwear, such as a shoe, includes an upper and a sole. The upper may be formed with an outer layer and a floating textile layer relative to one or more portions of the outer layer. The floating textile layer has an apparent elongation that is less than an apparent elongation of the outer layer in response to an equal tensile force applied to each of the floating textile layer and the outer layer along a same axis of orientation. The differential in apparent elongation of the outer layer and the floating textile layer may increase wearability and functionability of the upper.

An article of footwear has a sole structure with a resilient outer layer. The outer layer includes a continuous region and a discontinuous region. The continuous region and the discontinuous region have different hardnesses.
