See those people walking jauntily, a bounce in their step? Well maybe it’s not so much the nice weather and might be the music they’re playing, from their shoes. Dada footwear is releasing the Code M System, basketball sneakers with a built-in MP3 player. It can hold up to 100 songs and comes with a pair of wireless headphones. Transfer songs with the USB port on their sides and blast off tunes from the speakers. Only turn off about the musical footwear might be its $200 price tag.
