Yes, which is fine for me for training (remarkably similar stats to your beloved adidas AdiZero Mana, by the way) yet not quite as similar to the Hyperspeed you reference. The Racer ST is more substantial, not as curved. For racing, I think I want something of a bit flatter flat, though I do anticipate giving the T7 a try. Incidentally, if you do wind up wanting to stick with the Green Silence, with a 15% discount code at Runningwarehouse.com they tend to be quite reasonable. I got my pair of GS for free and through my sponsor I can get Brooks shoes for about the cost that Double spends on his adidas outlet store shoes, so price will not be an object for the next pair.
