    摘要: The present disclosure provides footwear with an internal metatarsal guard and a related manufacturing method. In the depicted embodiment, the metatarsal guard is internal in that it is located under the outer layer of the footwear. In the depicted embodiment, the existence of the metatarsal guard can be visually detected from the outside of the footwear being that the metatarsal guard is located in a raised area in vamp of the footwear. The footwear is constructed such that the metatarsal guard does not impinge into the foot volume of the footwear, and the metatarsal protection also is arranged and configured to maintain a high degree of flexibility in the footwear.
