If you really want to get beat up for your sneakers, these will pretty much guarantee that will happen. Yes, these "Hi-tech" shoes feature such 21st century innovations as a CD player. Yeah, that won't skip or anything as you run around. The built-in speakers look like they were jacked from a late-80s Oldsmobile, and the design of the shoes themselves is pretty old school as well.
Yeah, that means it's a concept, one that has pretty much zero chance of ever seeing the light of day. That's especially true since we've seen similar, better-thought-out versions of these stupid shoes before that never actually made it to market. Best to stick with shoes that are designed to be comfortable rather than act as an iPod replacement, no?
