This article talks about the new running shoe trends that are emerging in 2013. Firstly, “minimalism” in running shoes are key, especially having light-weight running shoes. Also, proper cushioning of the shoe must be taken into account and the range of heel-toe heigh differential ranges from 0 to 8mm, and 14 to 25mm of foam and rubber between the foot and the ground. New materials (i.e. foam, plastic formulations, mesh coverings and outsole rubber) are starting to form, as well as new manufacturing techniques. This serves as an opportunity for Adidas to stay on top of the trend and to meet and satisfy consumer needs/wants.
