Flexible cleats for flexible footwear (e.g., with natural motion sole structures) include a cleat structure that generally has the appearance of a cleat that has been separated into individual component parts by one or more flex grooves formed into the sole structure. Such structures provide additional flexibility at the areas of the cleats so as to avoid a “stiff” feeling in certain areas and/or during certain activities. The flexible cleats may be arranged around one or more intersections of flex grooves provided in a sole member, optionally in the form of an array of sole pods provided at least in a forefoot area of the sole member.
