I got ya here bro. There are two different pairs. One is the regular mids and the other has A3 technology. A3 is similar to that of shoxs but a little less material and more give. The shocks run through the whole lenth of the foot. This shoe is great for the impact absorbition, way better than the traditional Nike Shox and much more cost effective. It's a little flat footed so I'd say more for post players ar people with wider feet. Reasonably priced and a great shoe if your over the Shox hype. You'd probably want to hit up Footaction for these.
