I am not really into sneakers. For instance, the only pair of sneakers I own are a charmingly worn out pair of Jack Purcell canvas converse.. ..Not exactly an athletic shoe. However, I can say that I have a heightened sense for jewelry and accessories. Lush, luxe, sumptuous, chic. A few words that come to mind. So when Nike released their latest concept sneaker--Nike Zoom Superfly R4, ..I tuned in. Not necessarily for the streamline performance aspects of it--as it is being positioned as a sprinting shoe, just in time for the London 2012 Olympics--but, for the jewelry-emblazoned bottom machined into the neon-green leather upper. The shoe, to say the least, is quite sexy.
