Recent collaborations between fashion designers and sports brands emphasize the connection between fashion and sport. A case in point is Y-3, Yohji Yamamotos partnership with athletic shoe brand Adidas. Womens Wear Daily reported in March 2011 that some companies are consulting with doctors and engineers in their efforts to make performance apparel that has "comfort, lightness, and style." Meanwhile, recent runway collections have featured adaptations of classic sports attire, such as Manolo Blahniks high-end high heels modeled on utilitarian duck boots.
