I've emailed reebok couple times times and finally got a response. Thank you for asking Reebok. We are very happy to have Steve as a member of our team. He is currently wearing our VELOCITY DMX which is available in stores now. As of today I do not have any information regarding products made exclusively for Steve or any products that will be featuring his name but you can be sure that will change in the future. Thanks again for contacting Reebok. The DMXperience Damn...I thought they were already making his own brand. Oh well I'm sure he will have his own shoe after he wins ROY.
I know that he and Allen Iverson are wear the same brand of Reebok shoe. Steve will sport the outdoor series, while The Answer will wear the indoor series (or the other way around, can't remember).
Found these at Footlocker, must be a different colour worn in All Star weekend http://www.footlocker.com/catalog/stylesummary.cfm?TID=1000-21140018332121180235663&VID=brands&branch_id=60374&group_id=189874&bottom=1
