I'd have to agree with the majority of other posters here and that this is a great model by Adidas. It's actually pretty roomy for an Adidas and fit wise, falls into the sizing category of the supernova's, Adistar's, response series runners etc. Order your typical Adidas running shoe size with this model, seems pretty spot on Adidas running shoe size standard, even a bit roomier.

Extremely stable throughout the heel area due to the Powerbounce feature.  Luxurious toe box area in both width and height for Adidas. I don't usually purchase a shoe for its looks but out of the 70 pairs + of Adidas shoes I own, this model appears to get the most looks from others, if that's important to you. I personal have the black pair in this particular model. Traditional Adidas heel cup and will accommodate and hold the narrowest of heels in place. This particular model might even double well for a trail runner also considering its stability and rugged, durable heel area and well cushioned forefront.

Although this model I'm sure will accommodate many, I'd say that if you're a neutral, slightly heavier runner, heel striker and seeking a stable heel area that you would probably really dig this model.

Downside, unlike many of its counterpart upper-end Adidas class cousins this particular model rings in a tad heavier and mine in a size 12 rings the weight bell at approximately 14.1 oz. but solid stability comes with a price I reckon.  Overall, if you find this model on sale, add it to your collection, it is a unique, well thought out design, eye catching solid performer offering stable comfort and am sure will fill the bill for many of the Adidas admirer.
