The invention relates to heeled footwear such as a shoe or boot comprising a sole assembly and a heel part. The heel part comprises an insert formed in a first material. The insert comprises a core body delimited by an upper surface, a lower bottom surface, and an outer surface connecting the upper and lower surfaces. At least a part of the outer surface is encased/enclosed in a second material different from the first material. The outer material forms an outer contour layer of the heel part, and the sole assembly comprises an outsole formed in the second material, said second material being softer than the first material. The outsole and the outer contour layer are designed to be formed in one piece providing an outer sole unit being one component.
