When was the last time you bought sneakers?

Speaking for myself, it's been quite a while. And apparently, a lot has happened since, judging by the following sales blurb for the Air Jordan XXI:

"The Nike Air Jordan XXI has a full-grain leather upper, an advanced venting system and heat dissipation technology, Dual-depth DNA traction pattern and IPS (Independent Podular Suspension) with interchangeable cushioning technology that can be tuned for either full impact protection or maximum responsiveness."

Should you still be undeterred (unlike me), here's the info.
