The Code M system is integrated into the shoe’s heel and tongue. Its memory gives the device the ability to hold up to 10,000 songs with a 48-hours battery life. A USB port on the lateral side of the shoe allows downloading of music and re-charging of the battery. Another important element in the system is the wireless headset, which picks up music from the shoes as far away as 100 feet.The company plans to sell Code M products primarily through the company’s normal retail outlets, but Willis also intends to market the shoes through electronics retailers and catalogs where consumers are comfortable buying technology-based products. Suggested retail for Dada’s basketball line employing the Code M system will be $199.99.
